Maintenance

CAUTION

Ensure that the pump cannot be operated accidentally. Never operate the pump if covers or other parts of the 
pump are disassembled. Never operate a defective or damaged pump.

Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed 

by the pumping system. The pump might be contaminated with the process chemicals that have been pumped during 

operation. Ensure that the pump is decontaminated before maintenance and take adequate precautions to protect 

people from the effects of dangerous substances if contamination has occurred.

WARNING

Wear appropriate safety-clothing when you come in contact with contaminated components.

WARNING

For cleaning or removing deposits of the valves and diaphragms, use a suitable solvent. The use of 
any solvents must be used in accordance with your local health and safety regulations.
