Double Stage Water Ring Vacuum Pump

(Double Stage)

SHENOVAC Water-ring Vacuum Compressor(Liquid Ring) Pumps are of rotating positive dis-placement Pumps. These pumps are not only usedas Vacuum Pumps but can also be used asCompressors too. The Pump compresses gas byrotating a vaned impeller which is mountedeccentrically to the axis of the Pump casing.Sealing water forms a moving cylindrical ringagainst the inside of the casing. This creates aseries of seals between the impeller vanes andliquid ring.

Gases drawn into the Pump through an inlet portget trapped in the impeller cells, are com- pressedand goes to the second stage where they getcompressed again, due to reduced volume causedby the rotation of the impeller, are dischargedthrough exhaust port. Further, the process willallow the pump to automatically invent thequantity of liquid that will be discharged throughexhaust port thereby removing the heat ofcompression from the Pump.

The Main Casing and almost all the components ofthe Pumps are made from Cast Iron except theshaft and impeller. However, to meet specificapplications, we can offer the Pumps & theircomponents with special materials like SS-304/SS-316 on request. SHENOVAC Water-ring VacuumCompressor (Liquid Ring) Pumps are available inDouble Stage. The Double stage pumps are muchbetter choice if we handle solvents at highervacuum level at 720 mmHg subject to provision ofthe sealant water level is below 30 deg C &pressure at the site is 760mm Hg.
