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 2.5 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 optimized by Busch for 50 years, with a constant focus on both economy and reliability of operation.

High efficiency and energy-efficient drive units have resulted from this development. These vacuum pumps are fitted standard with heavy-duty carbon fiber composite vanes. 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 ensure optimum oil separation of even the smallest oil particles from the exhaust air.

This series is perfectly suited for continuous operation in low operating vacuum ranges such as in vacuum packaging. The compact construction enables the R 5 rotary vane vacuum pumps to easily fit into existing machines.

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

The R 5 series includes many more models than described here. Specialized types of R 5 are available for certain applications such as pumping oxygen.
