R 5 Oil-Lubricated Rotary Vane Vacuum Pumps

Ultimate pressure: 0.05 - 20 hPa (mbar)

Nominal pumping speed 50 Hz: 3 - 1600 m³/h

Nominal pumping speed 60 Hz: 4.8 - 1800 m³/h

The robustness and operational reliability of oil-lubricated R 5 rotary vane vacuum pumps have long made them the industry standard. Every day over 3 million R 5 vacuum pumps worldwide provide dependable service under the harshest industrial conditions.

Safe and cost-effective

Rotary vane technology has been continuously developed and optimised by Busch over the decades, with the emphasis on operational reliability and efficiency. R 5 rotary vane vacuum pumps are known throughout the industry for their modern and energy-efficient vacuum generation, in a wide range of applications. Whether for intermittent or continuous use, you can rely on the R 5.


These compact R 5 vacuum pumps owe their robustness to proven rotary vane technology with recirculating oil lubrication. This guarantees a consistently high vacuum level which can cope with the toughest operating conditions. When fitted with a gas-ballast valve (optional), vapours can be pumped without condensation.


R 5 – proven and reliable. Over 3 million pumps in operation worldwide.
