Operation Principles of AODD Pump | All Pumps

Center port diaphragm pumps have the suction side and discharge side orientated towards the front or back centered between the two ends of the pump. Pjmps from ” https: From Wikipedia, the free encyclopedia. Webarchive template wayback links Articles needing additional references from November All articles needing additional references. Consent I agree to receive information from verderair.

If you are unable add find the product that you are looking for then please contact us via sales castlepumps. Acting as a separation membrane between the compressed air and liquid, the elastomeric diaphragm applies pressure to the liquid column, while also balancing the load in order to remove mechanical stress from the diaphragm.

Diaphragm pump

The diaphragms are working as separation wall between the air and the liquid. When the pressurised sodd, Diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised air to the backside of Diaphragm B. The compressed air pushes diaphragm number two away from the center block.

Live Support Distributor Login Graco Husky Explanation Cross Section. Unmatched in quality, durability and availability, there’s no question as to why more and more industries are coming to Yamada for their pumping aovd.


You may unsubscribe from these services at any time. The pressurised air forces Diaphragm B away pmups the center while pulling Diaphragm A toward the center via the common shaft. DM-2 Diaphragm Monitor System. With the right material consideration, diaphragms can seal over a wide range of pressures and temperatures without needing lubrication or maintenance.

In pump chamber number one the opposite occurs. Want to discuss your requirements? They do not leak, offer little friction, and can be constructed for low pressure sensitivity.

This diaphragm causes a press stroke moving liquid out of the pump. Diaphragm B is now on its discharge stroke, which forces the inlet valve ball in Chamber B onto its seat due to the hydraulic forces developed in Chamber B and the manifold of the pump.

Doing so, diaphragm number one is pulled toward the center block. Air operated double diaphragm pumps are able to benefit from variable flow or pressures just by adjusting the air supply.

Unsourced material may be challenged and removed. Talk to us today: It is common for smaller sized AODs to be portable. Refine aocd results by: Head 8 bar Max. The suction ball valve is being pushed away off its seat.

This allows them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean. Upon completion of the stroke the air valve leads the air again to the back of aaodd number one and restarts the cycle as described above. The air valve directs the compressed air to the back of diaphragm number one. Food and beverages Pharmaceutical Mining and construction Printing, paint and ink Waste water Petrochemical AODD pumps are self-priming and therefore have good suction capabilities, as well as being able to dry run without doing any damage to the pump making them aoodd for batch operations in industry.


Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry.

When aoed pressurized diaphragm number one has aodd the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve.

The air valve is located In the center section of the diaphragm pump. Our philosophy is quite simple. Don’t fill this field! Also known as air-operated double diaphragm pumps, they are used for endless applications in mining, industrial and general plant service. Head 70 M Max. Views Read Edit View history. We only store your data to communicate with you regarding our services.

The pump may take several cycles to completely prime depending on the conditions of the application. Castle Pumps are fully accredited to enable you to buy aodr confidence. An air operated double diaphragm pump has two diaphragms. Air Valve Technology Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability.
