It can transmit high-viscosity media, corrosive liquids and hazardous chemicals. The flow regulator can adjust the stroke length or motor frequency. 5. The diaphragm is pressed multi-layer composite structure, the first layer of super-toughness Teflon acid film, the second layer of EPDM rubber elasticity, the third layer 3.0mmSUS304 supporting core, the fourth layer is made of reinforced nylon fiber supplement, the fifth layer using complete package EPDM flexible rubber shoe, which can effectively raise liter diaphragm pot life. Widely used in petrochemical, chemical, power, metallurgy, mining, shipbuilding, light industry, agriculture, national defense and other industries.
