DBY electric diaphragm pump

DBY series of electric diaphragm pump as a new-type pump, enjoying expanded service life of diaphragm since the break-through of diaphragmatic material, becomes more widely used in petrifaction, ceramic, metallurgy and other industries to replace part of centrifugal pump and screw pump. DBY applies to the low tension situation that the discharge pressure is below 3kgf/cm2.
