Introduction

General
Dear User
Thank you for using the WinCAPS program from Grundfos. The purpose of this
program is to offer a complete tool that contains an extensive catalog of
Grundfos products and a sizing program to select the most suitable pump for
your application.
On top of that there is a comprehensive pump replacement function for heating
circulators and the possibility to produce professional quotations including
curves, drawings, quotationtexts, wiring diagrams etc. You can also export all
this in the most popular file formats including gif, bmp, txt, dxf, etc.
Last but not least the program contains the instruction and operating manuals for
nearly all pumps of Grundfos in multiple languages. Service drawings, exploded
views and partslists are available for all sewage products as well as several other
pumptypes.
The program is designed, developed and maintained especially by Grundfos in
order to make use of the wide experience of more than half a century designing
pumps and knowledge of applications. For the last 18 years Grundfos has
developed the Caps and WinCAPS software, so customers and professionals all
over the world can share and benefit from this experience.

Who should use this program?

WinCAPS has specific Generally, everybody who is involved with pumps in a professional manner will
advantages for all find this program useful, however there are certain specific groups of users that
professional users will benefit especially from this program as mentioned below.

Installers, Welldrillers, Industrial end users or Owners of
a Grundfos product

If you belong to one of these groups then you can use WinCAPS typically to
make selections from the catalog, by productnumber or by using the books on
the screen. If you do occasionally need to calculate a pump (in sizing), you will
probably only use the short standard question set. Also the replacement catalog
can be helpful when you need to replace an existing pump with a Grundfos
pump. We advice you to run the program straight from the CD in order to save
the space on the harddisk.

A Guide Using WinCAPS 7.4 Introduction • 1

Planners, Consultants, Engineers, Large installation
companies, Pump dealers and Students

If you are in one of the above groups you will probably appreciate, apart from
the catalog function, the advanced question sets in the sizing program and the
ability to make accurate energy consumption calculations based on your own
loadprofile (consumption pattern) You can also make comparisons against
existing systems and calculate savings and payback periods. Dimensional
drawings can be used as reference in new or replacement projects. It is advisable
to install WinCAPS on your harddisk or install it on a network.

Grundfos Staff and Service partners

This group uses WinCAPS as reference for all Grundfos products. Many pumps
have exploded views and partslists connected to them, which are useful when
ordering spareparts. Via E-Mail or fax, a salesman, service engineer or
wholesaler can send drawings, technical information, manuals and pumping
solutions to their customers. Regular updates of the database and the program
will always supply the latest information.
For news and updates please check.

WinCAPS is Freeware and even though Grundfos employs the highest standards
with respect to programming and testing WinCAPS, the company cannot in any
way be held responsible for damage that can be caused by the use of this, as a
result of calculations or as a result of installation on a computer.

Installing Wincaps

General
WinCAPS will run Stand Normally WinCAPS should start itself automatically when inserted in the CD
Alone from the CD ROM drive. If this does not happen please run the file quot;Setup.exequot; from the CD (In
Windows: Start/Run/Browse , select the CD ROM drive and double click on
quot;Setup.exequot;). Wincaps will start and asks whether you want to run the program
from the CD or want to install it on the harddisk.
Important: Even if you want to install the program on the harddisk, always try to
run it from the CD first. If for any reason the program will not start or function
(see ODBC installation), it will also not run after you installed it on the
harddisk. This saves you the time you would otherwise use to install it to the
harddisk.

If you want to install the program on your harddisk, the installation program
will guide you through this process. Depending on which functionalities and
files you want to install, you will need between 300 and 670 Megabytes.
WinCAPS takes from 300 up During the installation process the program allows you to select which
to 650 Mb harddiskspace, components you wish to install. We recommend installing the dimensional
depending on installed drawings, photos, service notes and quotation texts, because these are relatively
options and I/O Manuals small files. If you want to install the Installation and Operating Manuals (I&O’s)
please check the box in the left column (see illustration). The right column
illustrates the languages you may wish to include. Should you select all
languages, this will increase the size of your installation by more than 300 Mb!

Installation Dialog Box

If you run WinCAPS from the CD, you will have of course everything at your
disposal.
The program will create a program group named quot;Grundfosquot; from which you
can start the program. You can also uninstall Win CAPS from here. Now you're
ready to go……….

Problems with Installation

Acrobat Reader ®
The instruction manuals in WinCAPS are in the so called PDF format (Portable
Document File), which is the de-facto standard for electronic distribution of
manuals, and this program needs to be installed on your computer, to display
them.
If Acrobat Reader ® is not yet present on your computer, you can install it from
the WinCAPS CD ROM where there are several language versions of this
program present (AR*.exe) or download it from www.Adobe.com

ODBC Installation

The WinCAPS program uses a Microsoft Access database to store data. To
approach this data, Windows needs a so-called ODBC driver. Upon installation
WinCAPS checks whether there is already an OBDC driver installed on your
computer. If this is not the case, WinCAPS asks if you want to install the ODBC
driver that is included on the CD ROM. Also if you run WinCAPS from the CD
only, you will still need the ODBC driver installed on your harddisk. After
installation of this driver, WinCAPS should function properly.

A Guide Using WinCAPS 7.4 Installing Wincaps • 5

If WinCAPS detects during installation that an ODBC driver is already installed
on your system (which is the case with most Windows installations), the
installation procedure will continue, or if you want to run the program from CD,
the start-up procedure.
Error Messages It has appeared that in a very limited number of cases that the ODBC driver that
is already installed, conflicts with the one that is needed by WinCAPS. This
results in error messages such as quot;Can not make connection to serverquot; or
quot;Server error, Connection Errorquot;.
Even though WinCAPS uses standard Microsoft components (also the ODBC
drivers are standard components) there can be conflicts if a certain Windows
version is installed with a certain version of Microsoft Office using a certain
language. As you might know, there are multiple versions of Windows 95,
Windows 98, Windows 98 SE, Windows Millennium, Windows 2000, Windows
NT and Windows XP. On top of that they can be combined with Office 95,
Office 98, Office 2000, and Office XPwhich again can be installed in several
configurations. All these programs in their different languages can use different
ODBC drivers, which in theory should be compatible, but which in practice are
sometimes not.
Installing the ODBC driver If you want to install the Wincaps ODBC driver over your existing ODBC
from the WinCAPS CD ROM driver you can run the installation from the WinCAPS CD ROM. You start this
could lead to compatibility process by running the file quot;Setup.exequot; located in the
problems with already Wincaps/Installodbc/Disk1 directory on the CD ROM. Most probably this will
installed software have no influence on your already installed software and will allow WinCAPS
to function properly, however because of the possible combinations of already
installed software on your computer, Grundfos cannot in any way be held
responsible for the consequences that this ODBC installation will have on your
installed software.

For Windows NT and Windows 2000 users

WinCAPS makes a few entries in the Windows registry file (in future versions
this will be abandoned). If you are a user of Windows NT or Windows 2000 in a
network, it can occur that you are not allowed to update this registry, depending
on your user profile. This will also trigger the error message quot;Can not make
connection to serverquot; or quot;Server error, Connection Errorquot;.
In that case please contact your IT department or network administrator.

Network installation, guidelines for system
administrators

Small Networks
If you have a small network, or are sure that never more than a limited number
of people (up to 6 or 8 depending on the speed of your network) will work
simultaneously with WinCAPS do the following.
Copy the complete contents of the directory Wincaps and all the subdirectories
that are on the CD ROM to a directory on your network drive. Then make
shortcuts from the users computers to the file quot;Wincaps.exequot; in the Wincaps
directory on this network drive. Settings and ini files will be automatically stored

6 • Installing Wincaps A Guide Using WinCAPS 7.4

on the local users computers. The users must have rights to update the registry
file.

Client Server Installatie on Local Network.
If you have a slower network, or want to use the program with a large number of
users you should make a Client/Server installation.
Note:
Make sure that your network supports the TCP/IP protocol
You must have administrator rights in order to install the program the program
on the server
Insert the Wincaps CD ROM and make a full Wincaps installation on a server
from which you want to run Wincaps (you can call this directory for instance
quot;W:Wincaps Serverquot; where W is your network drive. This will take up around
600 Mb.
Go to the directory in which you have installed Wincaps and run the file
NetDBsetup.exe
The program will ask you to specify a path to which you want to have the
clientpart copied. Important: You cannot specify a path with a space in it. So you
might want to call it quot; W:wincapsclient quot;
Now Wincaps will put the files needed for the clientpart in this directory
(depending on the number of productranges installed this varies between 20 to
25 Mb)
A file called quot;NetDB.batquot; is also created in your Wincaps Server directory. If
you click on this file it will start running the serverpart of Wincaps. You will
now see in the bottom of your screen a button quot;WinCAPS NetDBquot; indicating
that the serverpart is running.
Go to a computer on the network that you want to run WinCAPS on, go to the W
drive and copy through the network the clientpart quot;wincapsclientquot; on the local
harddrive of this computer.
Create a shortcut on this computer to the file quot;Wincaps.exequot; in the clientpart on
the local drive.
Click on the shortcut and Wincaps will run as Client-Server Application.

Note: Also Install the Acrobat Reader on the local computers, this file is
available on the Wincaps CD.

The settings and projects are stored on the local harddrives, you can check or
change these directories in the quot;Options Menuquot;.
In order to make sure that Wincaps is always available for the network users,
include the file quot;NetDB.batquot; in the startup routine of your server, also the
performance is enhanced if this server is not used for any other heavy network
applications.

Please notice, that this NetDB server program must run all the time, when the
WinCAPS data is needed via the network. If the NetDB program is running, a
little icon titled quot;WinCAPS NetDBquot; is displayed in the task bar in the bottom of
the screen.

How to install and use WinCAPS
If a user wants to run WinCAPS on his own PC via the network, he needs to get
access to the application part just created by the NetDBSetup program. If the

A Guide Using WinCAPS 7.4 Installing Wincaps • 7

chosen destination path was located on a network drive, the user can just run the
WinCAPS.exe file on this network drive from his own PC, and the program
should be ready for usage. If there is no access to network drives, the application
files should be copied from the chosen destination path on the NetDB machine to
the users PC-harddisk. He can then run the WinCAPS.exe from the harddisk, and
the application should start.

Note:

To be able to keep the users up to date with the WinCAPS application, it might
be an advantage, to select a network drive for the application part of Win CAPS.
When a newer version of the WinCAPS CD ROM is available, uninstall the old
one on the NetDB machine, and repeat the entire process. Then the next time the
users start WinCAPS.exe, it will automatically be updated, if you chose the same
destination path for the application part as in the previous version.

Starting WinCAPS for the first
time, Setting the Options Menu

General
When you are starting WinCAPS for the first time, either from the CD ROM or
the harddisk, you can customize the program by using the quot;Optionsquot; menu. A
menu will now appear with four tabs, which are Application, Server, Company
and Units.

8 • Starting WinCAPS for the first time, Setting the Options Menu A Guide Using WinCAPS 7.4

Options Dialog Box

Setting the tabs

Application
In this tab you can control some standard program features such as:
Language: Here you set the language in which the program will operate.
Product Range: This feature controls which countries' product range will be
used. Grundfos markets its products worldwide and between countries and
continents the product range can vary. For a specific country version that is sent
out to customers, there is only 1 choice, for the versions for Grundfos internal
use, there can be more product ranges. The full international range (general)
holds around 80.000 items.
Directories: Here you can control where WinCAPS saves temporary files, the
project files and exported data.
Show Parts Numbers in Parts List: This feature is not available in all
versions and controls whether or not part numbers are shown in the partslist in
the exploded views in service drawings
Products for Service Included: Also this feature is not available in all
versions. Here the user can control if also data of pump series is displayed that
are discontinued but can still be used for service purposes.
Extended search panel in the catalog: Here you choose if you want to
have the standard or the extended search panel when you are in the catalog
mode.

Server
This tab controls the address of the server on which the WinCAPS database is
running. For a normal harddisk or CD ROM operation this is always set to local,
however the network administrator can choose to set a different IP address here
(see Client Server Installation)

A Guide Using WinCAPS 7.4 Starting WinCAPS for the first time, Setting the Options Menu • 9

Company
Here you can fill in your own companies address etc. This will be used in
quotations that you produce. The data is saved in the Windows registry file

Units
This tab defines which unit of measure are used by WinCAPS

Important: After you change any of the above settings WinCAPS will do a quick
restart. We advice you therefore not to change these settings when you are in the
middle of a sizing process or a quotation because you will loose your input.
When you are in a quotation and want to change the settings, save your work
first!

WinCAPS, a quick tour

How WinCAPS is built up
The catalog and sizing part of the program are divided in application areas.
Allocated to these areas are the Grundfos pump series. If you want to know
which series are allocated to which application, go to catalog and click on an
application book. Next will come up the books of the pump series.

Note.

In WinCAPS 7, the Grundfos dosing pumps (if present in the national product
range, see above in quot;Setting the Options menu/Application) are only available
through selection in catalog. This can also be applicable for certain other
product lines such as motors and accessoiries.

Important: Throughout the whole WinCAPS program the blue arrow
in the top right hand corner will always take you 1 step back!

The Four Program Areas

General
The four main program areas of WinCAPS consist of:
• Catalog
• Sizing
• Project
• Replacement

Following is a detailed description of these program areas and calculation
methods that are used. Some functionalities may or may not appear depending
on local settings and local product assortment (Grundfos is represented
worldwide by own subsidiaries or agents).
The design of the question sets follows a logical pattern to allow an easy
selection of your pumps.
Important: At any point in the program you can switch between these four areas.
Please remember that the settings and input that you made in a certain question
set will be saved untill the moment that you open a new question set.

16 • The Four Program Areas A Guide Using WinCAPS 7.4

The Catalog Tab

General
A very powerful feature of WinCAPS is the catalog function. Choosing catalog
with the button, a bookcase will open that contains books with the names of
applications in which you will find your pump.
If you are not certain which application holds the pump series you are looking
for, you can also choose the book that contains all products.
The range of books displayed in the bookcase varies dependent upon which
product range the user selects or which product range is defaulted in the version
of the program the user is using
The books displayed in this product set are as follows;
• Heating
• Air-Conditioning
• Pressure Boosting
• Groundwater Supply
• Domestic Water Supply
• Sewage and Wastewater

Service Drawings and Service quot;Accessoryquot; illuminate. Clicking on quot;Informationquot; will display the available
Kits Installation and Operating instructions, service information, exploded views and
parts lists. Clicking on quot;Accessoryquot; will display a list of available accessories
the pump selected.

Doubleclicking on a quot;+quot; sign in the partslistviewer will reveal a lower level for
the kit.

Important: The accessories are applicable for the whole product line that you
selected and not only the pump that is in the result grid. You have to choose the
correct accessory yourself from the accessory menu; e.g. if your pump has DN
40 connections, you need to select DN 40 flanges from the flanges database.

Double clicking on a specific product in the result grid will give you access to
the Pump Curve, Dimensional Drawing, Product Picture and Wiring Diagram on
the left side of the screen and All Data, Quotation Texts and a System summary
on the right side. All this data can be exported, printed or saved in a project.

Viewing the pump curve in the catalog area, extensive
possibilities.

Once a product has been selected from the product selection tables, in the catalog
section, a pump curve will appear on the left side of the screen in the viewer
window. This curve screen displays a few very sophisticated features.


To begin with, you may click anywhere in the curve area and the duty point (P2)
and the efficiency of the pump will be calculated dynamically. This efficiency
information is displayed in the top right hand corner of the left side viewer
screen. If you are viewing a curve of a non-speed controlled pump, the
calculated duty point is where the pipe resistance curve crosses the pump curve.

If you are viewing a performance curve of a speed controlled pump (which is
identified by a large blue area), clicking anywhere in this blue area will display
the dynamic duty point and the RPM of the pump related to this duty point.

Important: for speed-controlled pumps with E-Motors (E = integrated
frequency converter) (P1) is always displayed in the top right hand corner of the
viewer screen!

The button quot;Curve Settingsquot; activates the next important feature. Clicking this
button will show you the Curve Settings Menu with the following possibilities.
All curve settings are automatically saved untill the default values are restored
by pressing the “Default Settings “ button

Operating point.
You can choose to have no duty point displayed, the nominal (optimal) dutypoint
or a dutypoint that you can define yourself.

If there is already a static pressure in the system, you can input that here. The
pipe resistance curve will then start from that point on the Y-axis.

Impeller.

20 • The Catalog Tab A Guide Using WinCAPS 7.4

For some pumps series (e.g. the NK series long coupled end suction pumps)
there is a possibility to show a curve based on an impeller diameter of your
choice. (The desired diameter has to be within the limitation for the particular
pump, otherwise there will be no curve shown; clearing this field will restore the
default values). This is due to the fact that Grundfos can supply these pumps
with an impeller machined down to match the exact desired duty point if this is
requested.

Nominal Motor Speed
WinCAPS will allow you to fill in here a different motor speed to emulate the
effect on the pump curve of an electrical motor that has a different speed than the
fitted standard motor. WinCAPS allows an input of 5% under the original
nominal motor speed or up to the synchronous speed (2999 RPM for 2 pole
motors, 1499 RPM for 4 pole motors, 999 RPM for 6 pole motors).

Fluid.
IMPORTANT: These Here you can manually change the viscosity and density of the fluid that you are
calculations are only pumping (see the chapter quot;Working with Glycol solutionsquot;) Basically changing
applicable for “Newtonian the viscosity will influence the steepness of the curve and adjusting the density
Liquids”, check chapter will influence the power consumption. However also factors like the design of
Working with Glycol the pump, duty point, RPM and impeller size play a role in the calculation.
Solutions When the required power (P2) exceeds the fitted standard motor, the pump
curve becomes a dotted line.

Hydraulic Layout
In this part of the menu you can choose to emulate the curves of maximal six
pump working parallel or two pumps working in series. Also you can choose to
see the power curve, NPSH curve or the efficiency curve (eta). Ticking of
quot;Tolerancesquot; will display the curve tolerances according to ISO 2548 Annex B.
Important. Not all curves are available for all pumptypes and not all Grundfos
curves are according ISO 2548 Annex B, for details check your Grundfos dealer
or the Grundfos.com website.

Variable speed.
This feature allows you to alter the curve of a non-speed controlled pump into a
speed-controlled pump, thereby emu lating the effect of an external frequency
converter. If this feature is activated, the curve area will turn blue. Clicking
within the blue area will display the duty point and the corresponding RPM in
the top right corner of the curve. This serves as a reference point for the
frequency setting (Hz) of an external frequency converter. (The slip of the motor
has to be taken into account, so the setting may vary slightly). This feature is not
available for wet rotor motors or pumps with multiple curves.

Default Settings Button
This button will restore the default curve settings.

Important: The above features in the curve viewer are only available when you
selected a pump in the catalog mode. When you select a pump using the sizing
process, all settings will be preset. You can only choose whether to display the
power curve or not.


The Sizing and Selection Tab

General
The sizing tool is where Grundfos demonstrates it’s vast experience in pump
Design and application knowledge. The results are a very comprehensive, yet
easy to use program that usually produces a suitable pump for your application.
The sizing tool is divided into 7 main application area's that are subdivided into
additional sub-application areas. Depending on which product range WinCAPS
is accessing, applications and sub-applications may vary. It is possible to select
from all of the Grundfos product lines by using the quot;All Productsquot; button.
Each application comes with its own specific question set.
An important feature of these question sets is the possibility to quickly select a
pump using only basic input or by selecting the quot;Optimize Selectionquot; box, make
advanced calculations with regard to energy consumption, payback periods, load
profiles, cost of ownership etc.

Saving Question set Settings
All the input that you make in a question set, such as head, capacity, a load
profile, data on lifecyclecost calculation, etc. can be saved using the “Save as”
button. These settings can be reloaded again using the “Open” button.

The Question sets, a quick tour

Clicking on a button of an application will open up the question set. Even though
these questions are specific to the selected application, the basic design remains
the same throughout the whole program.

The basic question set is sufficient to make a quick selection. At the bottom the
basic question set there is a tick box for quot;Optimize Selectionquot;. Enabling this will
open up the tabs (sections): Advanced, Energy and Economy, these sections
control the outcome of your selection and enable energy saving calculations

22 • The Sizing and Selection Tab A Guide Using WinCAPS 7.4

Wherever you see a calculator icon, clicking this icon will open up a new screen
for selection or calculation.

Basic Input

In every question set a few items will always appear. These are questions to do
with the flow, head and electrical connection.
Very Important Function is A very important feature is the calculator button next to the quot;Search criteria
the quot;SearhCriteria for pump for pump typequot;.
typequot;

Clicking on this button will give you already a pre-selection of the available
pump types, based on the input that you gave in the previous question. This field
is also freely editable, for instance typing quot;UPEquot; as search criteria, will give
only look for the UPE pump series to fulfill the required demand; typing UPE
50 will only look in the UPE 50 etc.
If this conflicts with one of the previous set parameters in the question set, an
information message will appear why there was no selection possible.

Order of sizing results by “Evaluation Criterion”

The order of the results after pressing the sizing button, depends on the
“Evaluation Criterion” settings. By default this setting will be on Electricity
Consumption. This means that the pumpsolution that uses the least energy will
be displayed on top of the list. Of course this might not always be the cheapest
solution in price, or in lifecycle costs. Therefor it is also possible to order the
results according to these criteria.

Changing the red dots in the Performance Curve
The red dots represent the duty points. WinCAPS uses a default load profile.
You can change this by choosing quot;Optimise Selectionquot;, go to the Load Profile
section and change the load profile to quot;Full Loadquot; or your own customised
profile. This profile can be saved using the “Save As” button.

Intelligent Twin Pump Selection
When selecting a twin pump you can choose whether you want to have 1 pump
head acting as standby, or you want to have a parallel operation, which means
that the total requested capacity is divided over the two pumpheads. You select
this by using the below dropdown menu option.

A Guide Using WinCAPS 7.4 The Sizing and Selection Tab • 23

If the “Duty Standby” option is selection, WinCAPS will select twin pumps but
will show only 1 pump curve; in “Parallel Operation” mode, 2 pumpcurves will
be selected. On top of that WinCAPS will display in the load profile result on
screen, how many pumpheads are operational at a particular duty point.

The Question sets in Detail

The Heating Question set

The heating sizing area is mainly used to select pumps for heating systems or for
domestic hot water purposes.

The General Section

Flow, manual input or automatic calculation by pressing the calculator. By
answering a few simple questions, WinCAPS calculates the required flow.


Total Head - This field allows for manual input or automatic calculation by
pressing the calculator. When using this calculating program, the field quot;Longest
trackquot; is pre-filled and depends on the input from the flow calculator.
Speed Regulation list box - Upon selecting “yes” the program will select
pumps with integrated frequency converters (E-Pumps) as well as external
frequency converters. You may only select integrated or only external.
Pump Design list box - Choose between mayned rotor type (wet rotor), In-
line and end-suction (dry rotor) and long-coupled, end-suction (base plate
pumps). If you select the long coupled pumps, two more questions will appear
concerning the desired coupling type and the presence of an impeller neck ring.
For dry rotor and base plate pumps the number of motor poles may be selected.
Single or twin pump, list box.. For more details check the “Intelligent Twin
Pump Selection” section.
Electrical Connection input fields. Here you can define the available
electrical power source. Depending on local legislation, over a certain amount of
kW, a Star Delta motor start is required. WinCAPS can take this selection into
account to choose the correct pump.
Pump Connection. Choose you preferred pump connection. If you are not
sure, leave this field default (Any)
Pump Material. In order to limit the output in the result grid, you can choose
the desired material from an available list.
Max Operating Pressure. Here you can pre-define the pressure stage of the
pump.
Search criteria for pump. Important feature, check with the quot;Basic Inputquot;
section for explanation.
Evaluation Criterion. See the “Order of Sizing Results by Evaluation
Criterion” section.

The Advanced Section


Allowed Under and Oversize - This section enables the user to define in
percentages, how much variance for under or over dimensioning is allowed.
Specifically when varying up and down in a certain pump ranges. It is possible
to combine this feature with the quot;Search criteria for pumpquot; possibility i.e. type in
10% undersize, 10% oversize and search criteria quot;UPSquot;.
Number of Pumps and Reserve Flow - This section defines how many
pumps you may select to cover the total flow. If you select more than 1 pump,
you may specify the percentage of reserve flow that is being taken into account.
If you choose 100% reserve flow, WinCAPS will allocate 1 pump totally as
reserve, i.e. if you specify 3 pumps with 100% reserve, the total flow will be
divided into 2 pumps.
Pumped Liquid – This section allows you to define the pumped medium. If
you select glycol, you may input manual figures for viscosity and density or
click on the calculator button and have it calculated automatically, depending on
the type of glycol. Check the section quot;Working with Glycolquot; for more details.
Minimum and Maximum Liquid temperature - The input in these fields
not only includes or excludes certain pump ranges; it also determines the choice
of seal. If glycol is selected with a minimum liquid temperature under 0° C,
WinCAPS automatically searches for a pump with the correct seal. (This
function depends on local availability of pump types with the correct seal).
Minimum Inlet Pressure - WinCAPS checks the minimum inlet pressure,
combined with the vapor pressure of the liquid at the maximum liquid
temperature and the flow specified, is still within the NPSH limits. Depending
on the pump type, if the inlet pressure is too low, combined with a certain liquid
temperature and flow, there is danger of cavitation. WinCAPS will exclude
pump types with NPSH values that are not within this range. This may cause wet
rotors to be excluded from certain selections.
Maximum Flow Velocity - Input here may limit the choice of pumps. In
certain systems this velocity may not be exceeded, WinCAPS will exclude
pumps with too small a pressure flange or thread connections.

The Load Profile Section

Load Profile. An important feature of WinCAPS is the ability to provide an
accurate calculation of energy consumption, based on a given load profile.
WinCAPS lets you select between different load profiles (the default is a heating
pump profile). You can also define your own custom load profile or choose quot;
Full Loadquot; if the pump is always operating on a fixed duty point. This profile
can be saved using the “Save As” button
Control Mode. When selecting a load profile, you can define whether the duty
points are according a proportional curve (pipe characteristic) or on a constant
pressure line (both modes can be emulated in the E-Pumps of Grundfos).
Proportional setting gives the highest energy savings. The propotional pipe curve
can be according to a linear increase, or according to a measured point
somewhere in the line from which the propotional curve will then be calculated
as a square function in order to compensate for the friction losses.
Below are the examples of these operation modes, notice the different energy
consumptions in the load profiles.


Control Mode Constant Pressure

Control Mode Proportional Pressure Calculated (Linear)


Control Mode Proportional Measured, Setpoint at measure point 50%

Control Mode Proportional Measured, Setpoint at measure point 30%

When selecting quot;Full Loadquot; in the load profile, these options are not active.
Reduced Night Time Duty. Ticking of this box will emu late the nighttime
saving mode (duty point nr 5). This is not an option in all countries and therefor
this box might not appear.


Set point Reduction by remote control. Influence on set point of a clock
program or outdoor temperature control. Weighed mean value over time.
Heating season. Here you can define the length of the heating season, which
is used in the calculation of the energy consumption.

The Life Cycle Costs Section

This section is the source of input for your Payback period and Cost of
Ownership calculations. All calculations and input is based according to the
standards of Europump and the United States Hydraulic Institute. More
information on these calculations can be found on the Internetsites:
www.europump.org
www.hydraulicinstitute.com
Recommended literature on this subject is the publication Pump Life Cycle
Costs, published by and available from these two organisations.

All input fields in the question set are supplied with mouse-over pop up fields
which makes the application self-explanatory

Comparison With. This sophisticated feature allows you compare the pump
you select to an existing system or an alternative quotation.
If you tick on this box, a new tab will be opened called “LCC Comparison”
You can choose from a list of existing manufacturers and pumptypes by clicking
on the calculator buttons or fill in a P1 yourself, also by using the calculator
functionality


Based on input in the economy section you can make extensive energy saving and
payback time calculations

And sophisticated Life Cycle Cost calculations based on alternative solutions

For a detailed description of the calculation method please refer to the menu
option: Help/Manuals in Print Format/Life Cycle Cost


The Air-Conditioning Question Set

This question set is the same as the heating question set. However there is a
difference in the selection of pump ranges for this application.

The Pressure Boosting System Question set

Grundfos is the world leader in the field of pre-fabricated booster systems.
Selecting booster systems for potable water purposes depends heavily on local
legislation; WinCAPS offers a comprehensive tool for sizing and selecting these
systems.
This question set is designed to allow selection of pre-fabricated booster
installation sets (Turnkey Booster Sets) or design a custom system, using a
single pump or multiple pumps in parallel.

The General Section

Dimensioning Flow - This is the flow of all pumps combined.
Discharge Pressure - This is the pressure measured at the discharge of the
pump. Additionally, it is possible to calculate this pressure by pressing the
calculator button, taking into account a minimal discharge pressure at the highest
point (i.e. 36 psi) and the geodetic height and friction losses. (WinCAPS will
recalculate input in feet to psi)
Installation Type/Inlet Pressure/Suction Lift – Select the installation type
you want to design. If you select quot;Inlet Pressurequot;, which is normal if the
installation is connected to the water mains, you may specify the minimal and
maximum water pressure. WinCAPS verifies that the maximum water pressure
plus the discharge pressure, against a closed valve of the installation, does not
exceed the maximal allowed pressure for the total installation. If you select
suction operation, you must specify the suction lift, which is considered when
calculating the total head of the installation.
Speed Regulation – This is where you select various speed controls.
Electrical Specification Fields - Same as in the other applications.
Number of pumps – Select how many pumps you want in the installation.
The flow will be divided between the pump s. If you want reserve capacity, you
will need to select from the advanced section with quot;Optimize Selectionquot;. Select
quot;Dimensions according to standard-Anyquot; and fill in quot;100%quot; in the quot;Reserve
Flowquot; field.

The Advanced Section

Allowed Undersize - Indicate if you accept a flow that is a few percent under
the duty point. This avoids over dimensioning and leads to more economical
solutions.
On/Off Band - This is the bandwidth range that determines when the
installation will switch on and off to avoid constant starting and stopping of the
installation.


Maximum Operating Pressure – This field allows for defining the
maximum operating pressure of your installation.
Intelligent choice of tanks with your installation
(the availability of this function depends on local settings)
If a booster installation is non-speed controlled (On/Off control), there is always
a tank required on the discharge side to ensure a smooth flow to the users and to
limit the number of starts and stops per hour.
WinCAPS automatically calculates the size of tank required for your installation
and it allows for an existing tank, if it’s already installed. Two fields enable this
feature: quot;Existing Tank in Discharge Pipequot; and quot;Tank required on the
Di scharge Sidequot;.
The calculation goes as follows:
• If neither of these fields is completed, WinCAPS will calculate the
correct installation. You will see a checkmark in the quot;Systemquot;
column of the product selection table indicating that an additional
item has been selected. WinCAPS automatically includes a tank,
depending on the flow. This tank is sufficient for speed-controlled
installations, however for non-speed controlled installations
(On/Off) this tank may be too small.
• If you double click on one of the selected installations, located on
the right side of the screen, the text viewer appears with the sizing
results. If the tank is too small, a note will appear, indicating that
the switching sequence is too high and to verify the required tank
size.
• If this occurs, return to the advanced input section and complete the
field quot;Tank Required on Discharge Sidequot; with a volume that is
adequate. WinCAPS will verify the size and select the required
tank from the database, or if the tank is too small WinCAPS will
display an error message. The automatic tank selection feature
may be disabled by entering quot;Nquot; in the Tank Required field.
• If there is already a tank installed, you just type in the size of this
tank in the field quot;Existing Tank in Discharge Pipequot;. WinCAPS
will verify that the size of the tank is adequate. If this is not the
case WinCAPS will come up with an error message.

Important: WinCAPS does not add the volumes in the two fields quot;Existing Tank
in Discharge Pipequot; and quot;Tank Required on the Discharge Sidequot;. If you want to
re-use your old tank, simply determine the size of the total required tank using
the quot;Tank Requiredquot; field and divide the result between your old and a new tank.

Dimensions According to Standard – You may select between several
standards that apply booster sets produced in your area. If you select, quot;DIN
1988quot;, already rules such as reserve flow, maximum number of starts per hour,
flow velocity etc. are taken into account. If you select quot;Anyquot; manual input is
required. The pre-selection of Standards may vary by country or region.

The Load Profile Section

Here you can select the Load Profile of the installation. (See the Heating
Question set)


The Life Cycle Costs Section

Please refer to the description of the Life Cycle Costs Section in the Heating
Question set. The only difference is that there is no list of possible replacement
installations. If you want to compare energy saving against an existing
installation, you need to fill in the number of kWh per year used by the old
installation.

Important: If you choose to assemble your own booster set using the sub-
application quot;Single or Multipump Systems quot; you will of course get drawings and
specifications of the single pump and WinCAPS will suggest a suitable control
unit to let these pumps function together. Also in the quot;Advancedquot; section you
can select pump types and flange sizes.

The Groundwater Question Set

The groundwater question set has changed extensively compared to previous
versions. The catalog will allow you to select from a very broad range of
Grundfos submersible pumps. The question set is constructed in such a way that
professionals will find an easy correlation between their real-world situations
and the program. This is demonstrated through a series of graphics with
hotspots. When the optimized selection is selected, input may be done through
the hotspots on the graphics.

The General Section
The User may make a quick selection based on a limited number of parameters.
Dimensioning Flow - Requested flow for the pump
Dimensioning Head - The required head for the pump
Frequency/Phase/Voltage – This section allows for the electrical
specifications for the requested pump to be entered. The phase is defaulted to
quot;Anyquot; allowing for a wide selection. Should you choose 1 or 3 in this field, and
then under Voltage, only the voltages applicable are displayed.
Starting Method 3 Phase - WinCAPS allows the User to define what starting
method they wish to use with the pump. You may select between five starting
methods:
• Direct On Line - The pump is directly connected to the junction
box. Check your local legislation for the highest allowable start-up
current.
• Star Delta - The pump will start using a Star Delta switch to reduce
starting current. This requires a pump with a Star Delta motor,
which WinCAPS selects automatically
• Soft Start - The pump will start using a Soft Start module reducing
the starting current. The selected pump is DOL
• Autotransformer - The pump will start using an autotransformer to
reduce the starting current. The selected pump is DOL.


• Frequency Converter - The pump is connected to a frequency
converter and speed controller. WinCAPS will draw a curve for
variable speed. The selected pump is DOL.

Pump Connection Type - A pre-selection may be made if the pump should
have a Grundfos flange or thread. The sizes may be specified, but it is advised
to keep this on quot;Anyquot; allowing for a successful selection. Only when pumps
have two thread sizes (SP 46 and SP 60/Rp 3quot; or Rp 4quot;) is this feature useful.

Preselect Pump Type - This field allows Pre -Selection of a pump type that is
displayed at the bottom of the screen. You may select from the drop down list or
use manual input. Example, typing in quot;SP” displays all SP pumps and when SP
60 is entered, WinCAPS will try to find an SP 60 pump that matches the input
criteria. If this field isn’t completed, WinCAPS will select all available
groundwater pump lines, beginning with the lowest energy consumption. This
parameter may be changed to quot;Pricequot; in the quot;Profitabilityquot; section by checking
optimized selection box.

Optimized Selection in Groundwater
When optimized selection is chosen, you can dimension the pump, chosing from
9 different installation modes. Input can be given through the hotspots on the
drawing or by filling in the fields on the Tabs

This schematic drawing represents the quot;Well Installation with open Tankquot; installation
mode.

Installation/Head Section: Depending on which installation is selected,
the fields on this tab will change. Following are the descriptions of the fields:


Static Water Level: This is the depth in the well to the water level in rest
(pump is off); If there is no entry in the dynamic waterlevel flow, Wincaps will
use this field for the calculation of the head.
Dynamic Water Level: If a dynamic waterlevel is know from a test report
using a certain Test Flow, this level should be filled in here.
Test Flow: This is the flow of the pump which is used to measure the dynamic
water level and used in the test report of the well. From this the specific capacity
and drawdown of the well can be calculated.
Pump Setting: Here you specify how deep the pump is in the well.
Static Lift Above the Ground: This is the vertical distance between the
wellhead and the point, where the discharge pressure is measured.
Discharge Pressure: The required pressure in the line
Riser pipe and Discharge pipe Friction Losses: These can be calculated
using the calculator tool and will be added to the total head.
Tank Required on Discharge Side: Here you can define the tank size you
have available or want to install on the discharge side. WinCAPS will calculate
if the content is sufficient, taking into account that the maximum switching
sequence is not exceeded. (See Booster installations)
Discharge Pressure in the Tank. The required pressure in the tank.
On/Off Band: This is the bandwidth in which the pump will switch on and off
to avoid constant starting and stopping of the pump.

The Capacity Section
This section allows you to specify which capacity (dimensioning flow) the pump
should have that you wish to install. This is different from the test flow used to
measure the properties of the well. You may manually input your capacity per
day, per year or per hour. If you choose capacity per hour, you may define a
load profile (the default is Full Load). Additionally, you may define how many
hours per day the pump works on high/medium or low energy tariff.
Required Minimum Flow to Guarantee Cooling – If you require a
minimum flow, enter that figure here. WinCAPS will verify the selected pump
guarantees this parameter. If the minimum flow is outside the curve of the
optimal selected pump, WinCAPS will select the next best choice that meets the
dimensioning flow and the minimum flow requirements. If no pump may be
found an error message is displayed.
The Inputs Section
This section enables the User to specify or calculate additional items such as the
diameter of the drop cable, borehole diameter and advanced motor selection.
The Advanced Drop Cable Calculation Section
WinCAPS contains a sophisticated tool to calculate the required diameter of
your electrical drop cable. This calculation depends on the voltage of the pump,
length of the cable (input field quot;Cable length: Motor to Starter Box”), the
allowed voltage drop (input field quot;Voltage drop in the cable maximumquot;) and
the selected pump. In order for this calculation to work, you must complete the
field quot;Voltage 3ph/1phquot; in the General Section. You may either access this
calculation through a hotspot or on the quot;Inputsquot; section.
