12 Curve conditions C, CN Curve conditions The guidelines below apply to the curves on the following pages: Tolerances according to ISO 996, Annex A. The bold curves state the recommended performance range. The thin curves are only intended as a guide. The curves must not be used as guarantee curves. All curves are based on measurements at: 1 x 22 V, 6 z 3 x 38 V, 6 z. When the motor is running at the lowest or highest rated voltage, the pump performance will usually vary by ±1.5 3 feet at a given duty point. Specific minimum performance requirements necessitate individual measurements. The measurements have been made with airless water at a temperature of 7 F (~2 C). The curves apply to a kinematic viscosity of υ = 1 mm²/s (1 cst) 12

13 Curve conditions C, CN ow to read the curve charts Curves Q: P 2 : Eff: Pump performance at actual speed. Pump input, i.e. pump without motor. Total efficiency, i.e. pump with motor, is shown in the curve charts as Eff. NPS: Average values for all variants shown in chart 1. When sizing, make a safety allowance of at least 2 feet.

25 1 Further product documentation C, CN Sizing This section is based on different fields of application and installation examples, and gives easy stepbystep instructions in how to 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 builtin 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 stepbystep 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 2dimensional (2D) and 3 dimensional (3D) CAD drawings of most Grundfos pumps. These formats are available in WebCAPS: 2dimensional drawings:.dxf, wireframe drawings.dwg, wireframe drawings. 3dimensional drawings:.dwg, wireframe drawings (without surfaces).stp, solid drawings (with surfaces).eprt, Edrawings. WinCAPS Fig. 9 WinCAPS CDROM WinCAPS is a Windowsbased Computer Aided Product Selection program containing detailed information on more than 185, Grundfos products in more than 22 languages.
