FINDER DEX Liquid Ring Vacuum Pumps

FINDER DEX Liquid Ring Vacuum Pumps: robustness and high vacuum levels for industrial processes

The FINDER DEX liquid ring vacuum pumps are single-stage pumps for high vacuum levels, specifically designed for industrial applications requiring reliable, quiet operation and excellent resistance to wet or vapor-laden gases.

Thanks to their variable compression ratiosystem, they achieve high vacuum levels while maintaining excellent operational stability. Their design is characterized by isothermal compression, the absence of internal lubrication, and low maintenance, as the impeller is the only moving part.

The FINDER DEX range is highly valued for its versatility and ability to handle most gases and vapors, even when liquid carryover occurs.

Special material configurations and ATEX are available to meet the requirements of the most demanding industrial environments.
