WARNING!
EX pump in area at risk from explosion
–
Ensure correct operation in general, particularly of the
power end and bearings, by regular monitoring (for
leaks, noises, temperatures, smell ...).
–
Do not allow the pump to heat up because of lack of oil.
With lubricated metering pumps, regularly check the
presence of lubricant, for example by checking the fill
level, visual leak control etc. If oil is leaking, examine the
leakage point immediately and eliminate the cause.
–
Check the correct operation of the relief valve down‐
stream of the pump. In premises at risk from explosion,
the relief valve should prevent the gear from becoming
overloaded and becoming hot.
–
When cleaning plastic components, ensure that no elec‐
trostatic charges are generated by excessive friction. -
see warning label.
–
Replace wear parts, such as bearings, as soon as unac‐
ceptable wear is detected. (The nominal service life
cannot be calculated with lubricated bearings).
–
Only use genuine spare parts as replacements.
–
Only perform tests and repairs in compliance with DIN
EN IEC 60079-17 and only permit "experienced per‐
sonnel who have the requisite knowledge" to perform the
work.
–
These measures constitute the minimum protective
measurements stipulated by ProMinent. It is the duty of
the operator to eliminate any other dangers identified by
appropriate measures.
WARNING!
It is mandatory that you read the safety information and
specifications in the "Storage, Transport and Unpacking"
chapter prior to shipping the pump.
WARNING!
Warning of dangerous or unknown feed chemical
Should a dangerous or unknown feed chemical be used: It
may escape from the hydraulic components when working
on the pump.
–
Take appropriate protective measures before working on
the pump (e.g. safety glasses, safety gloves, ...).
Observe the safety data sheet for the feed chemical.
–
Drain and flush the liquid end before working on the
pump.
WARNING!
Risk of fingers being crushed
Under unfavourable conditions, the stroke axle or displace‐
ment body can cause crushing of the fingers.
–
Disconnect the pump from the mains power supply and
ensure that it cannot be switched on again by unauthor‐
ised persons.
