your best partner for vacuum


The EVR-series are robust Vacuum Roots Booster Pumps

These Roots pumps are excelent tools to boost up your pumping speed and the reach a much better ultimate vacuum. These EVR-series Roots pump are useally combined with the pre-vacuum pumps of the following series: EV-series, EVD-series. The pumps can be supplied with an optional bypass system and valve, this bypass system allows the Roots pump to be started already at atmosphere at the same time as the pre-vacuum pump. The pump has a magnetic drive, this magnetic drive eliminates allows the pump to run without a shaft seal, so it reduces downtime and service costs. Due to the lower ultimate vacuum the pump is oftenly used in applications like:

  • Vacuum packaging
  • Vacuum metallurgy
  • Thin film coating
  • Spae simulation
  • Freeze drying
  • Vacuum impregnation
  • Low density wind tunnels
  • Vacuum distillation
  • Drying and de-gassing
