3.6 Pump head position

If you remove the pump head before installing the pump in the

pipes, pay special attention when fitting the pump head to the

pump housing:

1. Visually check that the floating ring in the sealing system is

centred. See figures 11 and 12.

2. Gently lower the pump head with rotor shaft and impeller into

the pump housing.

3. Make sure that the contact face of the pump housing and that

of the pump head are in contact before you tighten the clamp.

Observe the position of the clamp before you

tighten it. Incorrect position of the clamp will cause

leakage from the pump and damage the hydraulic

parts in the pump head. See fig. 13.
