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.
CAUTION!
Warning of feed chemical spraying around
The metering pump can generate a multiple of its rated pres‐

blocked.
– Correctly install a relief valve in the discharge line down‐
stream of the metering pump.
CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the wetted parts of
the pump.
– Take into account the resistance of the wetted materials
when selecting the feed chemical - see the ProMinent
Product Catalogue or visit our homepage.
CAUTION!
Danger of injury to personnel and material damage
The use of untested third party components can result in
injury to personnel and material damage.
– Only fit parts to metering pumps that have been tested
and recommended by ProMinent.
