Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The in-
stallation and operation should also be in
accordance with local regulations and ac-
cepted codes of good practice.
1. Type designation
See pump nameplate.
The key below indicates the meaning of the letters
and figures of the type designation, e.g. GP 14-75-3.

2. Applications
The GRUNDFOS pool pump, type GP, is a horizontal
close-coupled centrifugal pump with self-priming
properties.
The main application of the GP pump is to circulate
water in swimming pools and it is usually installed
before the pool filter. The pump is designed for
pumping pool water being disinfected by chlorine.
The GP pump incorporates a removable filter basket
to filter out leaves and other solids.
