Description

In response to the over whelming demand received from the market, PROMIVAC has come forth with a Double Stage version of their vastly patronized Water-ring type Vacuum Pump. Each and every pump of this new series very successfully and effectively takes care of its respective job and hence as usual is held in similar high esteem the 'PROMIVAC' logo has already earned. PROMIVAC Double Stage Water-ring Vacuum Pumps are of Positive Displacement Type wherein the Impeller is mounted Eccentrically to the axis of the Pump Casing. 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.
