air operated diaphragm pump

The QBK diaphragm air pump has eight common specifications with diameters of: 10mm (3/8"), 015mm (1/2"), 025mm (1"), 040mm (1/2"), 50mm (2"), 65mm (2 1/2"), 80mm (3"), 100mm (4"). It comes in three materials: aluminum alloy, cast iron, stainless steel. Diaphragm pumps are equipped with different diaphragm materials including nitrile rubber, chloroprene rubber, fluorine rubber, and polytetrafluoroethylene, to meet the needs of different users according to different liquid media. Since its inception, this pump has been adopted by many units in petroleum, chemical, electronic, ceramic, and textile systems, placed in various special occasions to pump various media that conventional pumps cannot handle, and has achieved satisfactory results.

Diaphragm Air Pump is a new type of conveying machinery that can transport various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. In the painting and ceramic industries, Diaphragm Air Pump have already taken a leading position, while in other industries such as environmental protection, wastewater treatment, construction, sewage discharge, and fine chemicals, they are expanding their market share and have an irreplaceable position that other pumps cannot fulfill.
