Main Functions

Rotates to agitate service liquid and form an annular liquid ring. Periodic volume change of the liquid ring realizes gas suction, compression and exhaust for vacuum pumping. Transmits drive power, builds negative pressure through media agitation and sustains pump suction performance. Partially balances hydraulic loads and reduces unit vibration.

Structural Form & General Materials

Gray cast iron for standard conditions; stainless steel for corrosive media. Blade-integral casting construction; key connection for torque transmission with the pump shaft.
