1. Introduction

IntroductionThis data booklet describes an extension of the NB, NBG, NK, NKG product range and thus of the complete end-suction performance range. The new pumps are designed according to EN 733 or ISO 2858. Information not specified in this data booklet can be found in the NB, NBE, NK, NKE data booklet, product no 96695638, and the NBG, NBGE, NGK, NKGE data booklet, product no 96695640.

The NB/NK 125-400 and the NBG/NKG 150-125-400 performance curves in this data booklet are updated with regard to efficiency and NPSH.

The NB/NK 150-315.1 and the NBG/NKG 200-150-315.1 are new pump models featuring improved duty points.

The pumps can be seen as a supplement to the existing NB/NK 150-315 and NBG/NKG 200-150-315 as all installation dimensions are same.

7. Further product documentation

WebCAPSWebCAPS 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.

WinCAPS

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.
