Liquid Ring Vacuum Pumps

Material Of Construction: Considering corrosive conditions of gas to be handled, construction of the vacuum pump is selected. It is available in complete cast iron, complete S.S., partial S.S. or partial bronze construction.
Vacuum: Up to 50 mm Hg. Absolute (Single Stage) and 40 mm. Absolute (Two Stage) using service liquid as water at 30°C. and higher (with water having less than 30°C)
Higher Vacuum: Higher vacuum can be obtained by using special oil or other service liquid. Also, a high vacuum can be achieved by using Liquid Ring Vacuum Pump as a backing pump in series with a mechanical booster.
Long Life and Low Maintenance Cost. : Pumps are robust in construction. Impeller with the shaft is only moving part. Impeller has no contact with the casing. Hence wear is negligible. These machines require very little maintenance and easy overhauling.
Vibration- free and Noiseless Operation: The sealant ring acts as a sound damper. Gas flow is the non-pulsation type. Hence machines are comparatively noiseless and vibration-free.
Liquid and Vapor Handling: Liquid Ring Vacuum Pumps are capable of handling large quantities of vapor. It has also the ability to handle a small amount of liquid in the suction stream without causing damage.
Handling solid particles: Continuous flushing action permits handling of certain fibrous materials
Low Starting Torque :
No Internal Lubrication
Sealing: Sealing is generally by a water-lubricated asbestos rope while mechanical seal may be used for the special application.
Circulation Of Service Liquid: As per requirement, service liquid can be circulated in the pump in open system, partially closed system or completely closed system.
Condensing Effect: When handling gas saturated with water vapor advantage can be taken off the condensing effect of the sealing ring.
As Compressor: Liquid Ring Pump can work as a compressor.
Oil-Free Gas: When the pump is used as a compressor, delivery of gas is absolutely oil free.
