Air driven pneumatic diaphragm pump is a new transport machinery , is currently one of the most innovative pump . Using compressed gas as a safety power source for a variety of corrosive liquid , large particle size liquid , high viscosity liquid, volatile, flammable, poisonous liquid can be pumped optical exhaustion . BSK has 4 series pumps: standard pumps, high pressure pumps, powder pumps, FDA&3A pumps. The different wet parts can be used for different applications. With the advanced air distribution system and stable working performance, BSK pumps are famous in chemical, ceramic, oil&gas, food&pharmacy, mining, water treatment, lithium battery production, building construction etc.
For FDA and 3A series “BSK” pumps, we have 1’’, 1 1/2’’, 2’’, 2 1/2’’, 3’’ and 4’’, the liquid parts are made of #316 stainless steel, we use Ra0.8 mechanical polishing on the surface of the inner and outer surface of the wet parts, which ensures our pumps have good performance and under CIP and good self-draining, there will be no residue in our pumps. Fully guaranteeing the safety of food transportation.
