Liquid ring vacuum pump
Liquid ring vacuum pump Are Available In Single- And Two-Stage Versions. In Single-Stage Versions, Compression Is Carried Out Once. In Two-Stage Versions, The Pumped Medium Is Compressed Again To Allow Higher Vacuum Levels To Be Achieved. Operation As A Compressor Is Also Possible With Some Models Of Water Ring Vacuum Pumps.
JD Vacuum Service - Liquid ring vacuum pumps
Depending On The Pumped Medium, Liquid ring vacuum pumps Can Be Operated As A Simple Continuous Flow System Or As A Partial Or Total Recirculation System.
The Operating Fluid Is Usually Water, But Other Liquids May Be Used If Required To Suit The Process Conditions.

Some Salient Features of Liquid Ring Vacuum Pumps
- Material Of Construction: Considering the corrosive conditions of the gas to be handled, the 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: A 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. The impeller with the shaft is the only moving part. The 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.
- Handling solid particles: Continuous flushing action permits the handling of certain fibrous materials
- Sealing: Sealing is generally by a water-lubricated asbestos rope while
mechanical seal may be used for special applications. - Circulation Of Service Liquid: As per requirement, service liquid can be
circulated in the pump in an 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, the delivery of gas is oil-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.
