PB series vacuum pumps 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.

Robustness and reliability of operation are the outstanding qualities of R 5 rotary vane vacuum pumps. These are just some of the reasons why proven Busch rotary vane technology has long established itself as the industry standard. Over 3 million R 5 rotary vane vacuum pumps are in operation worldwide in industry every day.

Rotary vane technology has been continuously developed and optimized by Busch in the course of over 50 years, always with a strong focus on economy and reliability of operation. High efficiency is the benefit of this continual development.

R 5 rotary vane vacuum pumps are characterized by high pumping speeds even in low pressure ranges and therefore rapid evacuation times. They feature highly durable Busch fibre-reinforced epoxy resin vanes as standard, ensuring optimum performance together with long service life. The specially designed exhaust filters provide excellent oil separation.

PB series R 5 rotary vane vacuum pumps are extremely compact due to their integrated motor and transmission, making them the ideal choice for fixed installations.

Maintenance can easily be carried out by the operator. Apart from changing oil and filters at regular service intervals, no further maintenance is required.

R 5 rotary vane vacuum pumps stand for advanced, energy-efficient vacuum generation in a wide variety of applications in industry throughout the world. You can always rely on the R 5 – whether us

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 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.
