The Suction Cycle of an Air Operated Diaphragm Pump:

Step 1: Suction
One diaphragm creates a suction action when being pulled back from the housing

Step 2: Discharge
The other diaphragm simultaneously transmits the air pressure to the liquid in the housing, pushing it towards the discharge port.

During each cycle the air pressure on the back of the discharging diaphragm is equal to the head pressure on the liquid side. Air operated diaphragm pumps can therefore be operated against a closed discharge valve with no adverse affect to the life of the diaphragms.

Trebles stock a large number of air operated diaphragm pumps, with our core range coming from the leading supplier of Tapflo.
