WARNING!
Risk of fingers being crushed
Under unfavourable conditions, the stroke axle or dis‐
placement body can cause crushing of the fingers.
– Disconnect the pump from the mains power supply
and ensure that it cannot be switched on again by
unauthorised persons.
WARNING!
Risk of injury from the fan impeller
The fan impeller beneath motor's fan cowling can cause
severe injuries while it is turning.
– The pump must only be connected to the mains
voltage with the fan cowling closed.
WARNING!
Hot oil and hot components
The hydraulic oil and the hydraulic end may become
very hot when the pump is exposed to heavy loading.
– Allow the pump to cool before starting work.
CAUTION!
Never adjust the pressure relief valve.
Unsuitable spare parts for the valves may lead to prob‐
lems for the pumps.
Only use new components that are especially
–
adapted to fit your valve (both in terms of shape and
chemical resistance).
– Use the correct spare parts kits. If in doubt, refer to
the exploded views and ordering information on our
website www.prominent.com.

Clean the discharge and suction valves only one after
another as they cannot be differentiated using the arrow
markings.
For orientation: Should you have a dismantled liquid end
in front of you, the suction valve is on the side of the dia‐
phragm rupture sensor.
