CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the parts
of the pump that come into contact with the chem‐
ical.
– Take into account the resistance of the wetted
materials and the ProMinent Resistance List
when selecting the feed chemical - see the
ProMinent Product Catalogue or visit ProMi‐
nent.
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 con‐
nected 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 may spray out of the hydraulic com‐
ponents if they are tampered with 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.
–
Ensure that the system is at atmospheric pres‐
sure before commencing any work on hydraulic
parts of the system.
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.
