Water Ring Vacuum Pump

A balanced cylindrical rotor with hollow hub with series of curved blades running freely in eccentric casing. The sufficient sealing liquid, usually water, forms a solid ring on periphery of casing due to the centrifugal force. Since rotor is rotated in eccentric casing the blade creates working spaces whose volume increases as rotor rotates from lower to upper vertex and decreases as the rotor rotates from upper to lower vertex. The uniform distribution of working spaces on rotor periphery results in continuous suction and exhaust of gases.There is only one rotating part - balanced rotor running with close clearances without any metallic contact with other parts.The Pump has cylindrical control plates having ample area for inletoutlet port fitted with close clearances to the rotor. Axial clearances are not to be maintained and so it is very easy while in maintenance. A fitter conversant with Centrifugal Pump can handle our Vacuum Pump very conveniently. Surprisingly this Pump maintenance is less than an electric motor.
