Diaphragm Pumps also known as Air Operated Double Diaphragm Pump (AODD), are a type of reciprocating positive displacement pump in which liquid is pumped by a reciprocating diaphragm, which is driven by a solenoid, a mechanical drive, or a fluid drive. Other versions are air operated Pump has inlet and outlet check valves. Diaphragm Pumps have good dry running characteristics; they can be up to 97% efficient. Diaphragm Pumps can handle highly viscous liquids.

Features

Diaphragm Pumps contain a reciprocating diaphragm and inlet and outlet check valves.

Applications

Diaphragm Pumps have many applications in general plant service where the liquid being pumped has high solids content or high viscosity.

Recommended Media

Diaphragm Pumps pump water and relatively thin liquids (won’t pump thicker oils). Normally not used for liquids containing solids. Available in alloys for corrosive services.

Advantages

Diaphragm Pumps handle a wide range of liquids, including liquids containing solids. Pump is seal-less, and can run dry without damaging the pump.
