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 in continuous operation
is ensured by recirculating oil lubrication and state-of-the-art precision manufacturing.
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 RA 0160 – 0302 D are driven by
a directly flange-mounted standard electric motor, with an efficiency class of IE3.
