POSITIVE DISPLACEMENT: RECIPROCATING PUMP

Air-operated double-diaphragm (AODD) pumps, also known as air-operated diaphragm (AOD) pumps, are a type of positive displacement pump powered by compressed air. They are incredibly versatile, making them a dependable solution across various industries. These pumps can handle nearly any type of fluid, from water to more difficult substances like sludges, slurries, abrasives, corrosives, as well as viscous and shear-sensitive products.

Air-operated diaphragm pumps feature a straightforward design, which makes cleaning, servicing, and maintenance both easy and cost-effective. Key components such as the diaphragm, check valves, air valves, and valve seals are available in a variety of materials, ensuring compatibility with a wide range of fluid types.

Operating Principles  How AODD Pumps Work

AODD pumps operate without the need for electricity, as they are powered by compressed air. The left and right diaphragms are connected by a single shaft, allowing them to move in sync.

When compressed air moves the air valve, one diaphragm is pushed toward the outer wall of the pump, forcing liquid out through the outlet. As this diaphragm moves, it pulls the opposite diaphragm, creating a cavity that draws liquid into the other side. This cycle repeats as long as the pump is supplied with compressed air.
