4.1 Cleaning
4.2 Demounting the pumphead
1. Isolate the drive from the electrical supply.
Close any shut-off valves in the suction and
discharge lines and disconnect these lines.
Refer to the manual of the pump.
2. Loosen the fasteners (A) of the coupling guard
and remove the coupling guard (B).
Warning
When cleaning the pump do not use a
high-pressure spraying pistol. This might
damage the seal and the bearing.
To demount the bare shaft hub the pump
must be separated from the drive. This can
be done in two ways: demounting the
pumphead from the support set or
demounting the drive from the support set.
