Water Ring Vacuum Pump with Cast Iron or Stainless Steel Construction
1. Water Ring Vacuum Pump Introduction
2BV series vacuum pump has small volume, compact structure, directly connected motor, while installation, put it in horizontal plane, no need chassis.
2BV series vacuum pump works basing on water ring principle, that is, impeller is installed eccentrically inside of pump body, after the pump start up, working liquid forms liquid ring(which is concentric with pump body ) inside of pump body, impeller passes motor power to liquid ring. Liquid ring pulse periodically between the impeller vanes, while in pulsation, gas is suctioned in through disk suction inlet and discharged from disk exhaust vent.

3.Water Ring Vacuum Pump Advantage
1. The direct-coupled design is easy installation and can save space.
2. The pump has the cavitation protection port opens(or connects with the separator) in the case of ensure maximum suction effect to eliminate the noise of cavitation and protect the pump.
3. 2BV whole series are all use the aluminum bronze impeller with high strength and raise its corrosion resistance and durability. If the liquid flows parts adopt stainess steel, the pump can work in the more hard condition.
