10 Decommissioning and disposal

Decommissioning

WARNING

• EX-pump only: metering pumps and their periphery must be maintained or

decommissioned by qualified or authorised personnel!

• For all metering pumps for metering inflammable media applies: Starting up and

emptying only supervised by a competent person.

• When decommissioning the pump, ensure that all dirt and chemicals are cleaned from

the housing and particularly the liquid end.

• Always take suitable precautions when using hazardous chemicals!

• Ensure that the equipment is de-pressurised!

왘 Disconnect the pump from the mains.

왘 Empty the liquid end by placing the pump on its head and allowing the chemical to drain

out.

왘 Rinse the liquid end with a suitable material, thoroughly rinse the liquid end after use with

hazardous materials!

If decommissioning is only temporary, maintain the correct storage conditions:

Storage temperature: -10 to +50 °C

Air humidity: < 92 % relative humidity

Disposal

WARNING

Spring under tension!

Take particular care when disassembling the pump as the return spring (Item 5, Chapter 2.2)

is under considerable mechanical tension!

IMPORTANT

Observe your locally applicable regulations (particularly with regard to electronic scrap and

gear oil)!
