5" Air Operated Double Diaphragm Pump, 275 GPM

The body structure material of industrial heavy duty air operated double diaphragm pump is made from stainless steel that has long time service. The AODD pump driven by compressed air, can suck a variety of toxic, flammable, volatile liquid, acids, alkalis, corrosive liquids, paint, rubber and paint binders. It is no need for irrigation and suction lift is up to 7m, which is a perfect air tool for pumping the medium containing impurities.

Features

• Air operated double diaphragm pump adopts pilot operated type air valve to eliminate the air tool downtime and extend its service life. All the parts can be replaced when the liquid chamber is not opened.
• Designed with multiport, the pneumatic dual diaphragm pump can be installed easily.
• It structures with non-porous embedded diaphragm to improve the usage rate of diaphragm and make it more compact.
• Air powered diaphragm pump can be used as a movable-type material transfer pump because it has such advantages as small in size, easy moving, no need base, small occupied area and easy installation.
• It can be externally connected to electromagnetic valve for remote control. And the reversing valve requires no lubrication.
