Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps are used in different industrial areas to create process vacuum. In this equipment, a compression chamber seal is created by the rotation of a water-filled pump body and an eccentrically placed impeller. Usually, the sealant is made of water or another suitable liquid. These liquid ring vacuum pumps are a safe and reliable choice to manage dirty and critical gas/vapor services since it has contactless components and is easy to use.

A wide range of highly efficient Liquid Ring Vacuum Pumps by Pompetravaini and Gardner Denver Nash are available at PumpAir Solutions. They are the most well-known brands in the industry because of their innovative engineering and designs for a variety of vacuum pumps. These liquid ring vacuum pumps are ideal for a wide array of industrial applications because of their unparalleled efficiency and premium quality.

Working Principle Of Liquid Ring Vacuum Pumps

The liquid sealant and impeller are the two components of a liquid ring vacuum pump that are most important for producing a vacuum. Water is the most often used liquid sealant. The vacuum pump’s impeller is situated between two port plates at an angle to the casing’s centreline. The centrifugal force produced by the impeller’s circular movement makes the gas become trapped in small areas. The liquid takes the form of a ring and leaves a vacuum area. Hence, because of the eccentric positioning of the impeller, the space becomes large and the process gas is drawn in through the suction slot.

As the impeller continues to rotate, the spaces decrease in size and the gas is compressed. Then the exhausted gas and residual water are separated and discharged through the discharge slot. The constant flow of cooler seal liquid replaces the older seal liquid and the process continues.

Special Features Of Liquid Ring Vacuum Pumps

• Easy Maintenance – The only moving component in liquid ring vacuum pumps is the rotor. As a result, there is less wear and easy and affordable maintenance is possible. 
• Longer Pump Life – Since there is less wear and tear, the pump can perform constantly, hence providing a long service life. 
• Continuous Operation – The pump can run continuously at any vacuum level without affecting performance.
• Accepts Carryover – The pump remains harmless from solids, moisture, slugs, chemicals, etc. as these are discharged through the discharge hole.
• Cool and quiet operation – The pump runs cool because it receives a constant flow of sealing water. It does not create a lot of noise either.
• Environment-friendly – Our Liquid Ring Vacuum Pumps do not pollute the environment or release oil into the plant rooms or sewers in any way, as these pumps do not need an oil change, condensers, etc.

Vapor Condensation of  Liquid Ring Vacuum Pumps May Produce a Capacity Bonus

When moist air or gas mixes with condensable vapors that enter the liquid ring vacuum pumps, the seal liquid, which is generally at a considerably lower temperature, cools them down. They therefore cool and combine with the seal liquid. These vapors now occupy less area compared to when they were a gas stream. This reduction in the volume yields a capacity bonus.
