Oil-lubricated R 5 rotary vane vacuum pumps are the industry standard due to their robustness and operational reliability. Over 2.5 million of these vacuum pumps are used worldwide everyday in tough industrial applications.
Rotary vane technology has been continuously developed and optimized by Busch over decades, with the emphasis on operational reliability and economic efficiency. R 5 rotary vane vacuum pumps are known throughout the industry for their modern and energy-efficient vacuum generation – whether being used intermittently or around the clock, you can rely on the R 5.
These compact vacuum pumps own their robustness to proven rotary vane technology with recirculating oil lubrication. This guarantees a constant high vacuum level that can handle the toughest operating conditions. When fitted with a gas-ballast valve (optional), vapors can be pumped without condensing.
