10 Maintenance
WARNING!
EX pumps in areas at risk from explosion
–
Ensure correct operation in general, particularly of the
power end and bearing, by regular monitoring (for leaks,
noises, temperatures, smell ...).
– Do not allow the pump to become hot due to a lack of oil.
Regularly check lubricated metering pumps for the exis‐
tence of lubricant, for example by checking the liquid
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).
– Use genuine spare parts for replacement.
– 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!
Fire hazard with flammable media
Only with combustible media: These may start to burn when
combined with oxygen.
–
During filling and draining of the liquid end, an expert
must ensure that feed chemical does not come into con‐
tact with oxygen.
WARNING!
It is mandatory that you read the safety information and
specifications in the "Storage, Transport and Unpacking"
chapter prior to shipping the pump.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components 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 unauthor‐
ised persons.
– Depressurise the system before commencing any work
on hydraulic parts.
