Description

Air powered double diaphragm pump is a high efficient pneumatic device that can be used for water purifier with BioFloc technology. This 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

Pneumatic dual diaphragm pump can transport high temperature media up to 130 ℃.
Adopt pilot operated type air valve to eliminate the AODD pump downtime and extend its life span.
It is designed with multiport to help you install it easily.
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 an electromagnetic valve for remote control. And the reversing valve requires no lubrication.

Applications

Tips: What is an air operated double diaphragm pump?

Air operated double diaphragm pump is given mane as pneumatic membrane pump that is a kind of positive displacement pump. AODD pump is also a kind of new conveyor, driven by compressed air, which can pump up a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. They are made of four kinds of body materials, no-metallic (polypropylene), cast steel, aluminum alloy and stainless steel. According to different liquid media, the AOD pumps use different diaphragm materials to meet different users’ needs. It can be placed in various special occasions used to pump a variety of conventional pumps that can’t pump suction medium.
