Sealant Liquid Operation

Liquid ring vacuum pumps operate using a sealant liquid, typically water or another compatible liquid, to create a seal between the impeller and the pump casing.

Robust Construction

These pumps are built with sturdy materials, such as cast iron or stainless steel, to withstand the rigors of industrial environments and ensure long-term durability.

Ability to Handle Wet and Contaminated Gases

Liquid ring vacuum pumps can handle gases with moisture, condensable vapors, or particulates without the risk of damage to the pump internals.

Cooling Effect

The liquid ring serves as a coolant for the pump, dissipating heat generated during compression and helping to maintain the pump’s temperature within safe operating limits.

Low Noise and Vibration

These pumps operate quietly and with minimal vibration compared to other types of vacuum pumps, making them suitable for noise-sensitive environments.


Liquid ring vacuum pumps are versatile devices capable of handling a wide range of gas volumes and pressures. They can be configured in single or multistage arrangements to achieve different vacuum levels.
