Graco Husky Explanation Cross Section. This constitutes one complete pumping cycle. 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.

Operation Principles of AODD Pump | All 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. This page was last edited on 21 Novemberat The diaphragms are working as separation wall between the air and the liquid.

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 an electric motor.

A diaphragm pump also known as a Membrane pump is a positive displacement pump that uses a combination of the reciprocating action of a rubberthermoplastic or teflon akdd and suitable valves on either side of the diaphragm check valvebutterfly valves, flap valves, or any other form of shut-off valves to pump a fluid.


The suction ball valve is being pushed away off its seat.

The working principle of a Verderair double diaphragm pump

Unsourced material may be challenged and removed. 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.

This diaphragm causes a press stroke moving liquid out of the pump. In pump chamber number one the opposite occurs. They do not leak, offer little friction, and can be constructed for low pressure sensitivity.

This action is similar to that of the cylinder in an internal combustion engine. An air operated double diaphragm pump has two diaphragms. Doing so, diaphragm number one is pulled toward the center block.

The compressed air pushes diaphragm number two away from the center block. This is all backed by the lowest cost of ownership in the industry. Air operated double diaphragm pumps are able to benefit from variable flow or pressures just by adjusting the air supply.

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.

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]. This allows them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean.

DM-2 Diaphragm Monitor System. 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.


The air valve directs the compressed air to the back of diaphragm number one. The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models. Our philosophy is quite simple.

Head 70 M Max. What is a High Pressure Pump? AODD pumps, or air operated diaphragm pumps, are positive displacement pumps driven by compressed air rather than an electric motor.

What is a Filter Regulator? It is common for smaller sized AODs to be portable. Head 8 bar Max. When the pressurized diaphragm number one has reached the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number adod by the air valve.

Retrieved from ” https: Please help improve this article by adding citations to reliable sources. 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.

Acting pumpd 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.
