GINKAI offers diaphragm pumps for transferring liquids through the repeated movement of a flexible diaphragm. As the diaphragm moves, it creates suction on one side of the pump chamber and pressure on the other. Each diaphragm movement draws liquid into the pump chamber and then pushes it out in a controlled cycle. As the liquid stays separated from the parts that drive the pump, the flow transfer process is cleaner and less prone to leakage.

Our diaphragm pumps include air-operated models powered by compressed air and electric models driven by an electric motor. We also provide plastic diaphragm pumps and metallic diaphragm pumps to suit different fluids and working conditions. These pumps can handle corrosive liquids, particle-containing fluids, high-viscosity media, volatile liquids, flammable fluids, and toxic liquids, with applications in chemical and petroleum processing, water treatment, food and beverage, mining, metallurgy, pharmaceuticals, biotechnology, coatings, and printing.
