Air Operated Diaphragm Pumps

Diaphragm pumps use a straightforward valve system to oscillate the diaphragm shaft laterally, connected to two flexible diaphragms composed of materials like Neoprene, Nitrile, EPDM, Santoprene, Hytrel, Viton Rubber, and PTFE for corrosive applications. Positioned in each corner of the pump, four free-floating ball valves respond to pressure variations in the pumped liquid, while flap valves are often utilized for pumping large suspended solids.

Air-operated diaphragm pumps ensure reliable operation across a spectrum of products, accommodating liquids with viscosities similar to water or highly viscous fluids up to approximately 30,000 cPs. Widely utilised in industries such as chemical, pharmaceutical, ink, paint, and food and beverage, these pumps are constructed from diverse materials like Cast Iron, Aluminium, Stainless Steel, Acetal, Polyethylene, Polypropylene, and PTFE.

Our diaphragm pumps come with various certifications, including Atex, FDA, 3A, and EHEDG ratings.
