NB, NBG, NK, NKG77. Further product documentationWebCAPS
WebCAPS is a Web-based Computer Aided Product Selection program available on www.grundfos.com.WebCAPS contains detailed information on more than 220,000 Grundfos products in more than 30 languages.Information in WebCAPS is divided into six sections: Catalogue Literature Service Sizing Replacement CAD drawings.
Catalogue
Based on fields of application and pump types, this section contains the following: technical data curves (QH, Eta, P1, P2, etc.) which can be adapted to the
density and viscosity of the pumped liquid and show the number of pumps in operation
product photos dimensional drawings wiring diagrams quotation texts, etc.
Literature
This section contains all the latest documents of a given pump, such as data booklets installation and operating instructions service documentation, such as Service kit catalogue and
Service kit instructions quick guides product brochures.
Service
This section contains an easy-to-use interactive service catalogue. Here you can find and identify service parts of both existing and discontinued Grundfos pumps.Furthermore, the section contains service videos showing you how to replace service parts.

Fig. 1 WinCAPS DVD
WinCAPS is a Windows-based Computer Aided Product Selection program containing detailed information on more than 220,000 Grundfos products in more than 30 languages.The program contains the same features and functions as WebCAPS, but is an ideal solution if no internet connection is available.WinCAPS is available on DVD and updated once a year.
Sizing
This section is based on different fields of application and installation examples and gives easy step-by-step instructions in how to size a product: Select the most suitable and efficient pump for your
installation. Carry out advanced calculations based on energy,
consumption, payback periods, load profiles, life cycle costs, etc.
Analyse your selected pump via the built-in life cycle cost tool. Determine the flow velocity in wastewater applications, etc.
Replacement
In this section you find a guide to selecting and comparing replacement data of an installed pump in order to replace the pump with a more efficient Grundfos pump. The section contains replacement data of a wide range of pumps produced by other manufacturers than Grundfos.
Based on an easy step-by-step guide, you can compare Grundfos pumps with the one you have installed on your site. When you have specified the installed pump, the guide will suggest a number of Grundfos pumps which can improve both comfort and efficiency.
CAD drawings
In this section, it is possible to download 2-dimensional (2D) and 3-dimensional (3D) CAD drawings of most Grundfos pumps.
These formats are available in WebCAPS:
2-dimensional drawings: .dxf, wireframe drawings .dwg, wireframe drawings.
3-dimensional drawings: .dwg, wireframe drawings (without surfaces) .stp, solid drawings (with surfaces) .eprt, E-drawings.
