Technical Specifications

Rotary vane technology is synonymous with a robust, functional construction. R 5 rotary vane vacuum pumps are characterized by an optimum design and perfectly synchronized components and materials. The constantly high vacuum level is ensured by effective and state-of-the-art precision manufacturing. The R 5 RC 0021 C features an oil return line for continuous operation.


A sophisticated oil separator ensures efficient use of oil. When fitted with a gas-ballast valve (optional), even large quantities of vapour can be extracted. A non-return valve in the inlet flange prevents the pumped medium from flowing back into the vacuum process after the vacuum pump is switched off. The R 5 RB/RC 0021 C is driven by a directly flange-mounted standard electric motor.
