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!
̈ Disconnect the pump from the mains.
̈ Empty the liquid end by placing the pump on its head and allowing the chemical to drain
out.
̈ 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
