WHAT TO DO IN THE EVENT OF A DIAPHRAGM FAILURE
If a diaphragm failure has been detected in pumps fitted with AirVantage,
see page 5 for shut-down procedure.
What to Check:
• Has product migrated to the sensor?
Corrective Action:
• If the sensor has been submerged in product, the sensor will need to be
replaced. Consult the AirVantage servicing section of the manual for detailed instructions.
What to Check:
• Has product contaminated the check valve cartridge?
Correct Action:
• If a significant amount of product has made it into the check valve assembly, then the unit will need to
be disassembled for inspection. If the check valve assembly is damaged, then it will need to be replaced.
Consult parts list for information.
Do not open when an
explosive atmosphere
may be present.
