WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be used: it may
escape from the hydraulic components when
working on the pump, material failure or incorrect
handling of the pump.
– Take appropriate protective measures before
working on the pump (e.g. safety glasses,
safety gloves, ...). Adhere to the material safety
data sheet for the feed chemical.
– Drain and flush the liquid end before working
on the pump.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic com‐
ponents if they are manipulated or opened due to
pressure in the liquid end and adjacent parts of the
system.
– Disconnect the pump from the mains power
supply and ensure that it cannot be switched
on again by unauthorised persons.
– Depressurise the system before commencing
any work on hydraulic parts.

multi-layer diaphragm.
– Do not "inspect" the insert discs.
