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!
Warning of feed chemical spraying around
Pumps which are not fully installed hydraulically can eject
feed chemicals from the outlet openings of the discharge
valves as soon as they are connected to the mains.
– The pump must first be hydraulically installed and then
electrically.
– In the event that you have failed to do so, press the
[STOP/START]
button or press the emergency-stop
switch.
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!
Danger from rupturing hydraulic components
Peak loads during the dosing stroke can cause the maximum
permissible operating pressure of the system and pump to
be exceeded.
– The discharge lines are to be properly designed.
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.
