4.2.7
Taking up of contaminated fluid
residues
Always wear protective clothing
when starting the pump.
Starting work
1. Connect and tighten the pulsation
damper.
2. Connect suction and pressure hoses
DN 50 for chemical applications or
pressure hose C 52-15 (do not use
corrugated stainless steel hoses).
3. Connect the flat suction box to the end of
the suction hose.
4. Connect a discharge elbow without
shut-off device to the end of the pressure
hose, min. DN 50.
5. Connect an earth strap to discharge
electro-static charging.
6. Connect and switch on the electric motor
(speed stage I).
7. Watch the pressure gauge.
4.2.8 Taking up of thin fluid films
Start the pump only when
wearing your personal protective
outfit.
Starting work
1. Connect and tighten the pulsation
damper.
2. Connect a flexible plastic hose DN 32 to
the suction port and acid resistant hoses
DN 50 or pressure hose C 52-15 to the
pressure port.
(
Do not use corrugated stainless
steel hoses
.)
3. Connect the residue pick-up to the end
of the suction hose.

electro-static charging.
6. Connect and switch on the electric
motor (speed stage II).
7. Watch the pressure gauge.
Note:
The pump primes immediately without
being filled. With this residue pick-up even
thinnest fluid films can be taken up, similar
to a vacuum cleaner, and pumped into a
transport drum for waste disposal, without
intermediate storage.
End of work
1. Switch off the electric motor.
2. Thoroughly flush residue pick-up, hoses
and pump with water adding a suitable
cleansing agent.
3. Disconnect the hoses.
4. Lay the pump on its side with the
pressure side down.

empty the pump completely.
