Activity
Means
1.1 Filling with separating agent
See Chapter
1.2 EX-relevant inspections
Ohmmeter
(measurement voltage
500...1000 VDC)
− Check grounding connection between ground connection of the pump and
the frame/trolley and between the individual components of the frame/
trolley: < 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 flushing 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 off. When the
air supply is turned off, a drop in pressure must be watched for.
Check seal of following modules:
− fluid section
− mounted fittings and regulators
