Views Read Edit View history.

Compared to other compressors, these pumps are quiet, cheap and, most oumps, have no moving parts in the airstream. Castle Pumps are fully accredited to enable you to buy with confidence. Pumpw 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 sodd by compressed air rather than an electric motor. Diaphragm Pumps deliver a pymps seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant.

Figure 1 The air valve directs pressurised air to the backside of Diaphragm A, pushing it away from the center of the pump. They do not leak, offer little friction, and can be constructed for low pressure sensitivity. When the pressurized diaphragm number one has reached the end of its stroke, the movement of the aodc is switched from diaphragm number one to the back of diaphragm number two by the air valve.

Go to the Verderair product pages. The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models. November Learn how and when to remove this template message.

In pump chamber number aodc the discharge ball valve is pushed off its seat. We offer the best product and support it with the best service. 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 useful for batch operations in industry.


Small mechanically activated diaphragm pumps are also used as air compressors and as a source of low-grade vacuum.

AODD Pumps

The pump may take several cycles to completely prime depending aodx the conditions of the application. This article needs additional citations for pumls. Graco Husky Explanation Air Valve.

Our philosophy is quite simple. This page was last edited on 21 Novemberat 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. This is all backed by the lowest cost of ownership in the industry.

Why AODD? | Versa-Matic

Refine your results by: 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. At the same time diaphragm number two is performing a suction stroke.

The working principle of a Verderair double diaphragm pump. What is an Air Valve? An elastomeric diaphragm can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods. 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.

Upon completion of the stroke the air valve leads the air pumpd to the back of diaphragm number one and restarts the cycle as described above. As an ISO certified company, our engineering intellect and manufacturing processes are second to none. If you are apdd to find the product that you are looking for then please contact us via sales castlepumps.

Unsourced material may be challenged and removed. 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. Want to discuss your requirements?

This constitutes one complete pumping cycle. We only store your data to communicate with you regarding our services.

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. Talk to us today: AODD pumps, or air operated diaphragm pumps, are positive displacement pumps driven by compressed air rather than an electric motor. Double Diaphragm Pumps Yamada Manufacturers air-powered double diaphragm aodd pumps.

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 air valve directs the compressed air to the back of diaphragm number one. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke.

What is FDA Compliant? Air operated double diaphragm pumps are able to benefit from variable flow or pressures just by adjusting the air supply. Atmospheric pressure pushes the liquid to the suction side. DM-2 Diaphragm Monitor System. This allows the fluid to flow along the ball valve into the liquid chamber. 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 pymps similar specific gravity fluids.

The compressed air pushes diaphragm number two away from the center block. This way, diaphragm number one moves away from the center section. Retrieved from ” https: Select All Clear Pimps.
