Air Operated Diaphragm Pumps

 

Diaphragm pumps use a very simple valve system to move the diaphragm shaft from side to side, which is attached to two flexible diaphragms. These diaphragms are available in a variety of material, including Neoprene, Nitrile, EPDM, Santoprene™, Hytrel & Viton Rubber. PTFE diaphragms are also available for highly corrosive/aggressive applications. The four ball valves, located in each corner of the pump, are free-floating and operated by pressure differences in the pumped liquid. When large suspended solids are required to be pumped, flap valves are also commonly used.

Air operated diaphragm pumps offer a reliable operation with the ability to pump a wide variety of products, operating on liquids with a viscosity similar to water up to a thick, highly viscose liquid at around 30,000 cPs.

They are extensively used within the Chemical, pharmaceutical, ink, paint, food & beverage industries, to name a few, and come in various body materials are available in cast iron, aluminum, stainless steel, Acetal, Polyethylene, polypropylene & solid PTFE.

We offer a number of pump certifications for diaphragm pumps, these certifications are Atex, FDA, 3A, and EHEDG rated. An Atex rating can be offered within certain pump ranges and will be suitable for use within a potentially explosive environment.

FDA approved pumps are a sanitary version for environments such as food production and the cosmetic industry. 3A rated pumps offer a higher sanitation level (than FDA Approved pumps), and are suitable for use within the pharmaceutical and the dairy industry.
