Liquid Ring Vacuum Pumps

The portfolio includes small, medium, and large units for various loads and process conditions. Solutions are available as standalone units or as part of complete vacuum systems for industrial applications.

Key Advantages
The liquid ring principle is inherently resistant to moisture, condensate, and mechanical impurities – the operating liquid continuously flushes the compression chamber and removes unwanted contaminants.

• Circulation of the sealing liquid also ensures lower operating temperatures and quieter operation.
• The design with a minimal number of moving parts contributes to simple maintenance and long service life.
• The pumps can operate stably across the entire operating vacuum range without interruption or complex control.

Specific Solution Options
NASH also offers two-stage liquid ring vacuum pumps for achieving deeper vacuum levels. The system can be combined with other vacuum technologies to optimize performance and energy efficiency according to specific application requirements.
