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. As an ISO certified company, our engineering intellect and manufacturing processes are second to none. The internal mechanisms of a double diaphragm pump can vary subtly between brands, however there is a common working principle applicable to all models.

Graco Husky Explanation Air Valve. Doing so, diaphragm number one is pulled toward the center block. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry. 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. This constitutes one complete pumping cycle. This page was last edited on 21 Novemberat 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.

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. We welcome the opportunity to earn your business.

Air Valve Technology Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability.

AOD pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air. An elastomeric diaphragm can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods.

Call Us sales castlepumps. The pressurised air forces Diaphragm B away from the center while pulling Diaphragm A toward the center via the common shaft. This way, diaphragm number one moves away from the center section. We only store your data to communicate with you regarding our services.

When the chamber pressure later increases from decreased volume the diaphragm moving downthe fluid previously drawn in is forced out. The working principle of a Verderair double diaphragm pump. 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. The air operated diaphragm pump design makes it suitable for use in a wide range of industries: The air valve directs the compressed air to the back of diaphragm number one.

Atmospheric pressure pushes the liquid aovd the suction side. AODD pumps, or air operated diaphragm pumps, are positive displacement pumps driven by compressed air rather than an electric motor. 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].

The air valve is located In the center section of the diaphragm pump. Views Read Edit View history. The pump may take several cycles to completely prime depending on pummps conditions of the application.

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. The air behind diaphragm number two is being pushed out to the atmosphere. This allows the fluid to flow along the ball valve into the liquid chamber.

Double Diaphragm Pump Supplier | Yamada Pump

The diaphragms are working as separation wall between the air and the liquid. Double Diaphragm Pumps Yamada Manufacturers air-powered double diaphragm aodd pumps. Compared to other compressors, these pumps are quiet, cheap and, most importantly, have no moving parts in the airstream. Apdd 8 bar Max. Terms of Use Privacy Policy Sitemap.

Select All Clear All. 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.

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 pumls in industry.
