WARNING

¥For all metering pumps for metering inflammable media applies: Starting up and emptying only supervised by a competent person.

IMPORTANT

Observe the safety notes provided in Section 1.

4.1Start-up

All general guidelines in the accompanying ”General operating instructions ProMinent® motordriven metering pumps and hydraulic accessories” apply.

Diaphragm pumps with mechanically actuated diaphragm: no additional measures necessary, however, version with diaphragm rupture indicator, version Ex“i”*, must be used on principle.

For all metering pumps for metering inflammable media applies: starting up and emptying only supervised by a competent person.

Inflammable media may only be lifted with stainless steel liquid ends. - For exceptional cases, where this is not possible, also PTFE with carbon may be used, our versions TT_ are made of conductive plastics. In this case, special attention must be paid by the user due to the lower mechanical stability.

4.2Maintenance

WARNING

¥EX-pump only: Wear parts (diaphragms, bearings etc.) of metering pumps used in potentially explosive atmospheres must be replaced after having completed 90% of their nominal product life.

¥The lubricant supply must be regularly checked for lubricated pumps, for instance by checking the fill level, visual inspection for leakages etc.

¥EX-pump only: check that the pressure relief valve downstream from the pump is functioning correctly!

The pressure relief valve must prevent the gearbox from being overloaded and overheating in explosion-threatened workplaces!

¥The proper general function, in particular of the drive, must be safeguarded by regular inspections (leakages, noises, temperatures, possible discoloration due to excess temperatures....).

¥Use original spare parts should exchange become necessary!

¥EX-pump only: When cleaning plastic parts, attention must be paid to not generating any electrostatic charge by rubbing excessively. - see danger sign.

¥EX-pump only: metering pumps and their peripheral equipment must be serviced by specially trained or authorised personnel!

IMPORTANT

After loosening the liquid end screws (e.g. to change the valves or diaphragm), the screws must be retightened clockwise to the specified tightening torque.

What requires maintenance?

•Secure fit of liquid end screws.

•Secure fit of metering lines (intake and delivery sides).

•Secure fit of head valve and intake valve.

•Leakage hole at end disc for moisture (indicates possible diaphragm failure).

•Operate pump continuously for a short period of time in order to check whether it delivers correctly.
