Proven technology, proven design –
decide for the best solution
The R5 PB 0004/0008 C belong to the Busch product family of proven R5 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 R5 PB series type page.
Series Type Page R5 PB Rotary vane technology is synonymous with a robust, functional construction. R5 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 R5 PB 0004/0008 C are driven by a directly coupled electric motor.
