Trouble Shooting Guide & Technical Data TROUBLE SHOOTING GUIDE NOTE :- Check all solutions before dismantling the pump. PROBLEM Pump will not start CAUSE SOLUTION Air valve assembly malfunction/Seizure Obstructed fluid line. Obstructed diaphragm chamber. Diaphragm failure causing fluid & excessive air to be expelled through the exhaust. Diaphragm seal failure. Air valve system malfunction. Air connected to exhaust. Erratic flow Check carrier for freedom of movement. Clean, oil & replace.
PRINCIPLE OF PUMP OPERATION This ball valve type diaphragm pump is powered by compressed air and is a 1:1 ratio design. The inner side of one diaphragm chamber is alternately pressurised while simultaneously exhausting the other inner chamber. This causes the diaphragms, which are connected by a common shaft secured by plates to the centres of the diaphragms, to move in a reciprocating action.

Exhaust Safety when pumping hazardous liquids WARNING! In the event of diaphragm rupture, pumped material may enter the air end of the pump, and be discharged into the atmosphere. If pumping a product which is hazardous or toxic, the air exhaust must be piped to an appropriate area for safe disposition. Flooded Suction Installation Submerged Installation Suction Lift Installation Exhaust Safety :When a diaphragm fails during operation, pumped liquid can enter and contaminate the air side of the pump.
