Double Stage Water Ring Vacuum Pump

Sealing water forms a ring which circulates concentrically within the axis of the casing. Process Gases drawn in through the Suction Port get trapped in the Impeller Cells, are compressed & travels to the second stage where they get compressed further and are discharged through the Exhaust port. The sealing water which forms the liquid ring is supplied at a pressure equal to the Discharge Pressure of the pump, which allows the pump to automatically make up the amount of liquid which is discharged through the Exhaust Port, therefore removing the Heat of Compression from the Pump.
