be documented by the repair personnel.
Activity Means
1.1 Filling with separating agent
See Chapter 8.2.3.1.
1.2 EX-relevant inspections
Ohmmeter
(measurement voltage
500...1000 VDC)
− Check grounding connection between ground connection of the pump and
the frame/transport cart and between the individual components of the
frame/transport cart: < 1MΩ
− Check conductivity between piston and grounding connection: < 1MΩ
These inspections are - relevant!
1.3 Testing for leaks
Air motor:
Test medium;
compressed air
Leak spray
Fluid section:
Test medium; suitable
Flushing agent
− Connect the air motor to the air supply 7 bar. To perform a leak test on the
device, the product pressure with the ushing agent is slowly increased in
increments until the maximum pressure indicated on the type plate is reached.
Close pump outlet. In each position (forward stroke and reverse stroke), let
sit for 0.5-1 minutes and listen for audible blowing o. When the air supply is
turned o, a drop in pressure must be watched for.
Check seal of following modules:
− uid section
− mounted ttings and regulators
1.4 General inspections
Torque wrench
Visual check
− Check tightening torque of various screws.
See Chapter 14.
− Check all ttings.
− Empty device in a controlled manner (Chapter 8.2.4) and depressurize
(Chapter 7.4).
− Check function of frame or transport trolley.
