PRINCIPLE OF PUMP OPERATION This ball valve type diaphragm pump is powered by compressed air and is a 2:1 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.
TROUBLE SHOOTING GUIDE NOTE :- Check all solutions before dismantling the pump. PROBLEM Pump will not start CAUSE Air valve assembly malfunction/Siezure Obstructed fluid line.
