FDA & 3A Diaphragm Pump Food Grade Standard

Food / Chemical Positive Displacement Pump Corrosion Resistant

Positive Displacement Pump Application and Advantage:

Pneumatic diaphragm pumps are operated with compressed air . diaphragm pumps is suitable for pumping fluids with particles, and various liquids, which are highly viscous, volatile, corrosive or toxic, as well as colloids. The pump body is made of aluminum alloys, cast iron or stainless steel. The diaphragm is made of high quality rubber such as Nitrile rubber, chloronorgutta rubber, fluoroine rubber. The diaphragm pumps are widely used in the petroleum chemical, electronic, ceramic, food and textile industries.
