Busch R5 RA vacuum pumps
The rotary vane pump that runs in practically every vacuum and packaging machine. Supplied new, with parts and service from one place.
Why customers choose the R5
The R5 is a single-stage, oil-lubricated rotary vane pump. It reaches an ultimate vacuum of 0.1 mbar and is built to run continuously, including at high ambient temperatures. That is why it sits inside traysealers, vacuum machines and thermoformers of practically every make.
We are a dealer for the R5 RA range. That means new pumps, the parts that go with them, and someone who knows your machine when something goes wrong.

How a rotary vane pump works
Inside the housing turns a rotor that sits off-centre. Vanes in slots in that rotor are pushed outwards by the rotation and run against the wall. That creates chambers which grow on the inlet side and shrink on the outlet side: air is drawn in, compressed and pushed out.
The oil lubricates, cools and seals. On the outlet side that oil is separated out of the air in filters and fed back, so the pump runs on a closed oil circuit.
