Caution!
Escaping pumped media can cause
burns to hands and arms.
Depressurise the pump casing.
Only then should you drain the pump.
Disassembly of the filter strainer (002):
1. Detach the star handles (004) to fasten
the filter cover (003).
2. Lift the filter cover (003) with both hands.
3. Remove the filter strainer (002) from the
filter casing (001) by turning it slightly.
Important!
Check the proper seat of the filter strainer during installation!
The handle of the filter strainer (002) generates the neces-
sary prestress through the mounting of the filter cover (003).
Installation of the filter strainer (002):
1. Insert the filter strainer (002) with floor
towards the front in the filter casing(001).
2. Push the filter cover (003) onto the filter
casing (001) with both hands.
3. Tighten the star handles (004) crosswise
by hand.
Caution!
Dry running the pump will destroy the
mechanical seal!
Before starting the pump, fill it and the
supply pipe with the pumped medium.
Then, de-aerate.
Danger!
The rotating impeller can cut or crush
people's hands and arms.
Observe section 3.5 “Shut-off proce-
dures”.
Danger!
Impermissible heating of the three-
phase motor can create a potentially
fatal explosive atmosphere.
It is imperative that the motor is kept
clean. This will ensure adequate ae-
ration.
7.6
Cleaning the filter strainer
The filter area of the filter strainer (002) must be generously
dimensioned. This makes long cleaning intervals possible,
even in case of strong soiling.
The soiling of the filter strainer (002) lowers the pressure
value. This can be recognised if the displayed value:
- is lower than the starting value (in case of a digital pressure
sensor)
- no longer corresponds with the locking indicator (in the
case of the pressure-and-vacuum gauge),
Clean the filter strainer (002) according to the degree of
contamination.
Important!
Before removing the filter strainer (002), close the pressure-
side and suction-side shut-off valves.
