3.4.3 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 figs 13 and 14.
2. Gently lower the pump head with the 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.
See fig. 15.

Check 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. 15.
