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.
