EVR-125
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 will be supplied with 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
