Pump & Machinery Co supplies high quality metal, plastic and sanitary Air Operated Double Diaphragm pumps for a wide variety of industries and applications.

These reliable pumps have many innovative features and are self-priming and can run dry without damage.  They can handle viscous, shear sensitive and abrasive products and solids in suspension.

Because they are air driven, AODD pumps can be used in locations where there are no electrical points or where electric motors are not desirable.  The flow rate can easily be increased or decreased by merely adjusting the air supply.
