When the chamber pressure later increases from decreased volume the diaphragm moving downthe fluid previously drawn in is forced out. 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.

Head 8 bar Max. Webarchive template wayback links Articles needing additional references from November All articles needing additional references.

AODD Pumps

From Wikipedia, the free encyclopedia. The suction ball valve is being pushed away off its seat. Air operated double diaphragm pumps are able to benefit from variable flow or pressures just by adjusting the air supply.

Castle Pumps are fully accredited to enable you to buy with confidence. We only store your data to communicate with you regarding our services.

The diaphragms are working as separation wall between the air and the liquid. The air valve directs the compressed air to the back of diaphragm number one. By using this site, you agree to the Terms of Use and Privacy Policy.

This article needs additional citations for verification. Yamada remains dedicated to the continuous development of the most complete line of air operated diaphragm pumps available today. When the pressurised diaphragm, Diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised zodd to the backside of Diaphragm B.


Terms of Use Privacy Policy Sitemap. 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]. November Learn how and when to remove this template message.

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

What is an Air Valve? The air behind diaphragm number two is being pushed out to the atmosphere.

AODD Pumps Air operated diaphragm pumps for all fluid types AODD pumps, or air operated diaphragm pumps, are positive displacement pumps driven by compressed air rather than punps electric motor. 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.

Call Us sales castlepumps. DM-2 Diaphragm Monitor System. The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models. 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. These diaphragms are connected by a shaft in the center section. 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.

The working principle of a Verderair double diaphragm pump. The pressurised air forces Diaphragm B away from the center while pulling Diaphragm A toward the center via the common shaft. This constitutes one complete pumping cycle. This diaphragm causes a press stroke moving liquid out of the pump. This allows the fluid to flow along the ball valve into the liquid chamber.


Please help improve this article by adding citations to reliable sources. The air valve is located In the center section of the diaphragm pump.

AODD Pumps & Air Operated Diaphragm Pumps | Castle Pumps

They do not leak, offer little friction, and can be constructed for low pressure sensitivity. Head 70 M Max. As the compressed air moves Diaphragm A away from the center of the pump into its discharge stroke, the pressure created within Chamber A pushes out the liquid through its discharge valve. We welcome the opportunity to earn your business.

Operation Principles of AODD Pump

The pump may take several cycles to completely prime depending on the conditions of the application. Split Manifold By utilizing one pump, Yamada Split Manifold Diaphragm Pump offers a design in which the inlet and outlet ports can be configured to multiple combinations; ideal for pumping or combining two similar specific gravity fluids. These same hydraulic forces lift the discharge valve ball off its seat in Chamber B, while the opposite discharge valve ball in Chamber A is forced onto its seat, forcing fluid to flow through the pump discharge.

The compressed air pushes diaphragm number two away from the center block. What is a Filter Regulator? This is all backed by the lowest cost of ownership in the industry. Doing so, diaphragm number one is pulled toward the center block. In pump chamber number two the discharge ball valve is pushed off its seat.
