Liquid Ring Vacuum Pumps Dealers in Kolkata

PRINCIPLE OF OPERATION : Liquid ring vacuum pumps are of the postive displacement type . Service liquid is regulated and due to the eccentrically mounted impeller, the service liquid is thrown towards the periphery of the stator thus forming a sealant ring .Process is trapped in this space between the impeller blades, compressed and expelled in a continuous suction exhaust cycle.           MATERIAL OF CONSTRUCTION: Stainless steel 316/304 impeller and shaft grinded all over. Tolerances is standard .All other contact parts in graded cast iron.     AS PER REQUIREMENT: Material of construction to be used as per customer requirement.   OUTSTANDING FEATURES: - Silent and considerable vibration free running. - Needs no silencer. - Mechanical Seals balanced on computerised machine. - Maximum vacuum using water as a sealant at 30°c and at sea level conditions.Dual stage model will be 720mm Hg vacuum - Negligible maintenance and easy overhauling procedures. - Modification for use as compressor possible.   PERFORMANCE CHARACTERISTICS DOUBLE STAGE Liquid ring Vacuum pumps   Liquid ring vacuum pumps for higher speed on request. * Capacity of Two stage pumps are for dry air and service liquid (water) at30°c sea level conditions. * We recommend to use two stage vacuum pumps for applications upto 24" Hp vacuum. * Service liquid flows are approximate,exact quantity will be determined by actual installations. * Any change in the interest of technical development are reserved.           PRRFORMENCE OF TWO STAGE VACUUM PUMP
