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 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.
The R 5 vacuum pumps are distinguished by high pumping speed even in low pressure ranges and therefore quick evacuation times. Durable rotor vanes guarantee long uptimes and the specifically designed exhaust air filters enable an excellent oil separation.
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 necessary.
R 5 rotary vane vacuum pumps are known throughout the industry for modern and energy-efficient vacuum generation suitable for all kinds of applications – whether being used intermittently or around 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.
The rotary vane technology enables a technically simple structure of the vacuum pumps. The consistently high vacuum level in continuous operation is guaranteed through circulating oil lubrication, perfectly coordinated materials and state-of-the-art and precise manufacturing. The oil separator, fitted as standard, ensures clean and oil-free exhaust thanks to its sophisticated extractor system with integrated oil return. When fitted with a gas ballast valve (optional), even large amounts of vapour can be processed. A non-return valve in the inlet flange prevents air from flowing back into the vacuum chamber when the vacuum pump is switched off. The pump is driven by a directly flange-mounted standard motor, efficiency class IE2.
