WARNING
Pumps used for radioactive materials cannot be returned to ProMinent after use! They will
not be accepted by ProMinent!
Repairs: These should only be carried out by qualified personnel (in accordance with Safety
section):
• Cleaning the valve
• Changing the diaphragm
WARNING
• Always take suitable precautions when using hazardous chemicals!
• Ensure equipment is de-pressurised.
NOTE
Take the exploded drawings annexed to the help.
Cleaning the discharge valve (PP, NP) for types 1000, 1005, 1605, 1601, 1602
NOTE
• Discharge and suction valves are different! Dismantle one after the other to avoid
confusion.
• Only use new parts, which fit your valve (in shape and chemical resistance)!
• The pump must be reset after replacing a valve.
• Insert an Allen key or similar into the smaller hole of the pressure connector and push
out the valve inserts.
Cleaning the suction valve (PP, NP) for types 1000, 1005, 1605, 1601, 1602
A suction valve is designed almost similar to a pressure valve.
Take care however that:
• both valve inserts are actually identical,
• an additional spacer is found under the valve inserts,
• in the liquid end a shaped seal 1 is used instead of an O-ring,
• the flow direction of the suction connection is reversed as for the pressure connector.
Cleaning the discharge valve (PP, PC, NP) for types 0708, 1008, 0220, 0420, 0413, 0713, 0232

A suction valve is designed almost similar to a pressure valve. Please ensure, however, that:
• the shaped seal is placed in the suction connector,
• only the O-ring is inserted into the liquid end and not the shaped seal,
• the flow direction for the suction connector is reversed as for the pressure connector.
