Customized Liquid Ring Vacuum Pump

Liquid ring vacuum pumps are dynamic positive displacement devices crucial for generating process vacuum across various industrial sectors including chemical, electrical power, environmental, food & beverage processing and packaging, marine, mining, oil & gas, pharmaceutical, pulp & paper, and textiles. These pumps employ water or other compatible liquids as sealants. Their straightforward operation, devoid of any contacting components, renders liquid ring vacuum pumps a secure and dependable option for managing contaminated and potentially hazardous gas streams. Furthermore, these pumps come in both single and dual-stage configurations and can be adapted into compressors, enhancing their versatility even further.

Accepts Carryover

Soft solids, moisture, slugs, chemicals and more will not harm the pump. These impurities will simply be washed out through the pump discharge.

Cool & Quiet Operation

The pump runs cool owing to the circulation of the sealing water inside the pump. The operation is relatively quiet – not exceeding 85 dBA.

Constant Operation For Any Vacuum Level

Pump can operate constantly and continuously at any vacuum level – from 29 in. Hg to atmospheric pressure.

Easy Maintenance & Longer Pump Life

Liquid ring vacuum pumps are robust in construction and have only one moving part, the rotor, which is mounted on a shaft supported by a set of bearings designed for a long service life of continuous operation. This benefits the user with less wear and simpler, affordable maintenance.


Liquid ring vacuum pumps are safe and reliable pumps for handling contaminated and potentially hazardous gases because they are very simple to operate and have no parts in contact with hazardous substances. Note: Disadvantages of this type of pump are the mixing of the pumped gas with the service liquid, and the high power consumption due to internal friction losses.
