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.
