Industrial Process Pumps

Air Operated Double Diaphragm (AODD)

Looking for a reliable, low-maintenance solution for fluid transfer? Spray Direct proudly supplies a comprehensive range of Air Operated Double Diaphragm (AODD) Pumps from industry leader Graco, designed for demanding industrial applications.

What is an AODD Pump?

An Air Operated Double Diaphragm Pump is a positive displacement pump powered by compressed air rather than an electric motor. It features two pump chambers, each with its own inlet and outlet check valves and diaphragm. The diaphragms are linked by a shaft, enabling simultaneous movement-hence the term double diaphragm.

As compressed air alternates between chambers, fluid is drawn in and pushed out in a continuous cycle. This rapid process ensures consistent flow and reduces outlet pulsation, making AODD pumps ideal for a wide range of industrial uses.
