3/4 inch air operated double diaphragm pump is a highly efficient compact pneumatic tool that adopts reliable pilot operated type air valve. The pneumatic dual diaphragm pump is small in size and easy to move, perfect for various usages, such as pumping a variety of toxic, flammable, volatile liquid, acids, alkalis, corrosive liquids, paint, rubber and paint binders. AODD pump also can help you clean not only sewage and residual oil from cruises or barges, but also sediment contaminants in shaft, tunnel and sewers.

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.
