The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models. Head 70 M Max. This is all backed by the lowest cost of ownership in the industry. If you are unable to find the product that you are phmps for then please contact us via sales castlepumps.

Figure 1 The air valve directs pressurised air to the backside of Diaphragm A, pushing it away from the center of the pump. We only store your data to communicate with you regarding our services. Yamada remains dedicated to the continuous development of the most complete line of air operated diaphragm pumps available today.
With the right material consideration, diaphragms can seal over a wide range of pressures and temperatures without needing lubrication or maintenance.
Castle Pumps are fully accredited to enable you to buy with confidence.
Operation Principles of AODD Pump
Atmospheric pressure pushes the liquid to the suction side. Acting as a separation membrane between the compressed air add liquid, the elastomeric diaphragm applies pressure to the liquid column, while also balancing the load in order to remove mechanical stress from the diaphragm.
As an ISO certified company, our engineering intellect and manufacturing processes pups second to none. Also known as air-operated double diaphragm pumps, they are used for endless applications in mining, pmps and general plant service.
DM-2 Diaphragm Monitor System. Views Read Edit View history. When the pressurised diaphragm, Diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised air to the backside of Diaphragm B. This allows them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean. The air valve is located In the center section of the diaphragm pump. These diaphragms are connected by a shaft in the center section.

Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry. November Learn how and when to remove this template message.
In pump chamber number one the opposite occurs. Graco Husky Explanation Cross Section. When the chamber pressure later increases from decreased volume the diaphragm moving downthe fluid previously drawn in is forced out.
Diaphragm pump – Wikipedia
AOD pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air. Our philosophy is quite simple. What is a High Pressure Pump? As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. An air operated double diaphragm pump has two diaphragms. When the volume of a chamber of either type of pump sodd increased the diaphragm moving upthe pressure decreases, pumsp fluid is drawn into the chamber .
From Wikipedia, the free encyclopedia. This allows the fluid to flow along the ball valve into the liquid chamber. 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.
They do not leak, offer little friction, and can be constructed for low pressure sensitivity. Compared to other compressors, these pumps are quiet, cheap and, most importantly, have no moving parts in the airstream.
