Overview

Air driven dual diaphragm pump with high efficiency and high pressure, is powered by compressed air to pump a variety of toxic, flammable, volatile liquid, high viscosity fluids, acids, alkalis, corrosive liquids and paint.

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 of Air Operated Double Diaphragm Pump

Tips: How to maintain an air operated double diaphragm pump?

Air operated double diaphragm pump is no need for any lubricant before and during you use it. But after you disassemble the pneumatic dual diaphragm pump or when you reassemble it, it is better to fill some proper grease between pitman shaft and pitman shaft sleeve. When you install the diaphragm clamp, you also can coat a layer of grease for sealing easily.
If you need to install the air valve and guide valve, it is better to fill a small amount of grease for better lubrication.
Before you install the AODD pump, you need to clean all the inside parts, check whether all the sealing parts are well sealed.
Air valve cover gaskets and air valve chamber gaskets have two sides that can’t be installed reversely. The upper guide valve should be confirmed in place before tightening bolts, otherwise it will damage the thimble. Four bolts on the guide valve should be balanced and not over tight, otherwise the shell valve will be damaged.
