Robustness and reliability of operation
are the outstanding properties of the R 5 rotary vane vacuum pumps. These are some of the reasons why proven Busch technology has long been established as the industry standard. Over two million R 5 vacuum pumps are in use worldwide in industrial day to day business.

Operationally reliable and cost-effective
The rotary vane technology has been continuously developed and optimised by Busch for 50 years, with constant focus on both economy and reliability of operation. High efficiency and energy-efficient drive units are the positive results of this development. These vacuum pumps are fitted with heavy-duty carbon fibre composite vanes as standard. These Busch vanes have been developed for tough operation of R 5 vacuum pumps and are manufactured exclusively at our own plant. The highly efficient oil separators are also a special development, as they guarantee optimum oil separation of even the smallest oil particles from the exhaust.

Service-friendly
Maintenance can easily be carried out by the operator. Apart from the change of oil and filters at regular service intervals, no further maintenance is neccessary.

R 5 rotary vane vacuum pumps are known throughout the industry for modern and energy-efficient vacuum generation suitable for all manner of applications – whether used intermittently or round the clock, you can rely on the R 5.

The R 5 series includes many more models than described here. Specialised types of R 5 are available for certain applications such as pumping of very wet gases and vapours, or discharging of oxygen or explosive gases.
