The R 5 PB 0004/0008 C belong to the Busch product family of proven R 5 rotary vane vacuum pumps. They have been designed as close-coupled vacuum pumps being thus very compact and perfect for installation in confined spaces. You will find more information on advantages, technology, accessories and spare parts, applications as well as a complete product overview on our R 5 PB series type page.
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 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 PB 0004/0008 C are driven by a directly coupled electric motor.
