Maintenance
WARNING
Metering pumps and their peripheral devices may only be
serviced by trained personnel and authorised persons!
PLEASE NOTE:
Service intervals: every three months, shorter intervals under
heavy load (e.g. continuous operation)!
The maintenance of the gamma metering pump is limited to checking
• the liquid end screws (tightness)
• the discharge lines (tightness)
• the discharge and suction valves (tightness)
• the leakage bore at the intermediate disk (dampness can indicate a
diaphragm rupture)
• that the pump is feeding correctly - for this purpose briefly operate the
pump in priming operation (simultaneously pressing the
key).

Trouble shooting/eliminating errors
14.1
Errors you can eliminate yourself
PLEASE NOTE:
In order to be able to eliminate small errors at any time we
recommend that you always have a set of spare parts - consisting
of diaphragms, valves, balls, seals and fuses!
You can find the order nos. for this in our product catalogue under
"Spare parts kit for gamma/4"!
WARNING:
For maintenance and repair work always rinse out the liquid
end first if dangerous or unknown media are used!
WARNING:
When metering dangerous or unknown fluids protective
clothing must be worn when working on the liquid end
(glasses, gloves)!
WARNING:
Always relieve the discharge line of pressure first before
working on the pump!
Always empty and rinse the liquid end!
Observe the safety data sheets of the metering fluid!
