Air Operated Diaphragm Pumps

Air Operated Diaphragm Pumps

One of the most popular types of pumps found in use in chemical and beverage processing and production. Trebles stock a huge range of this type of positive-displacement pump. These diaphragm pumps can also be used for biotechnology and pharmaceutical purposes.

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. Across the range there are models designed to cope with a variety of applications including paint, adhesives, oils, ceramics or hazardous chemicals – suited to different applications and environments.

Due to the long life and serviceability of these pumps, Trebles also keeps extensive spares and accessories in stock.
