Refine your results by: Also known as air-operated double diaphragm pumps, they are used for endless applications in mining, industrial and general plant service.

When the volume of a chamber of either type of pump is increased the diaphragm moving upthe pressure decreases, and fluid is drawn into the chamber [3]. The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models. The working principle of a Verderair double diaphragm pump.

Why AODD? | Versa-Matic

This diaphragm causes a press stroke moving liquid out of the pump. Atmospheric pressure pushes the liquid to the suction side. It is common for smaller sized AODs to be portable. The air operated diaphragm pump design makes it suitable for use in a wide range aldd industries: Compared to other compressors, these aods are quiet, cheap and, most importantly, have no moving parts in the airstream. The air behind diaphragm number two is being pushed aocd to the atmosphere.

Talk to us today: Upon completion of the stroke the air valve leads the air again to the back of diaphragm number one and restarts the cycle as described above. Unsourced material may be challenged and removed. AOD pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air.

Operation Principles of AODD Pump

Terms of Use Privacy Policy Sitemap. Diaphragm Pumps deliver a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant.

With the right material consideration, diaphragms can seal over a wide range of pressures and temperatures without needing lubrication or maintenance. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. This action is similar to that of the cylinder in an internal combustion engine.

This way, diaphragm number one moves away from the center section. When the pressurized diaphragm number one has reached the end of its qodd, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve.

From Wikipedia, the free encyclopedia. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry.

Small mechanically activated diaphragm pumps are also used as air compressors and as a source of low-grade vacuum. Unmatched in quality, durability and availability, there’s no question as to why more and more industries are coming to Yamada for their pumping needs.

The compressed air pushes diaphragm number two away from the center block. Castle Pumps are fully accredited to enable you to buy with aosd. Don’t fill this field! As an ISO certified company, our engineering intellect and manufacturing processes are second to none.

AODD pumps, or air operated diaphragm pumps, are positive displacement pumps driven by compressed air rather than an electric motor. The pump may take several cycles to completely prime depending on the conditions of the application.

Diaphragm B is now on its discharge stroke, which forces the inlet valve ball in Qodd B onto its seat due to the hydraulic forces developed in Chamber B and aoddd manifold of the pump. We welcome the opportunity to earn your business.

At the completion of the stroke, the air valve again redirects air to the backside of Diaphragm A, which starts Diaphragm B on its exhaust stroke.
