The main features

  • RVS liquid ring vacuum pump series is able to pump gases and vapours

  • Nearly isothermal compression of gases

  • No lubricant in contact with pumped gas

  • The service liquid can be separated from the gas in a liquid separator and can be recirculated either partially or entirely, after a proper cooling.

  • Safe operation and minimum maintenance

  • Reduced noise and vibration


KRVS units cover pump sizes from RVS 7 to RVS 60.
