R5

Oil-lubricated rotary vane vacuum pumps

r5_rd_0360_a

With the invention of the R5 oil-lubricated rotary vane vacuum pump, Dr Karl Busch has revolutionized food packaging. And today, we are the market leader in vacuum packaging.

However, the R5 is not limited to this application but represents the industry standard for a wide range of applications. Every day, over 3 million R5 vacuum pumps are in operation around the globe.

In the course of over 50 years, we have continuously developed and optimized rotary vane technology. Always with a strong focus on energy efficiency.

Throughout the industry, the R5 is known for its robustness and reliability. You can always rely on the R5 – whether used intermittently or around the clock.

A wide range of sizes, design options and accessories ensures that the R5 is the perfect match for many processes.

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

Operating principle

R5 rotary vane technology is synonymous with a robust and functional construction. In a cylindrical housing, a rotor with three vanes is mounted eccentrically. Due to centrifugal force, these vanes slide out and form chambers between themselves and the housing.

The pumped medium is trapped inside these three chambers. During further rotation, their volume is constantly reduced. Thereby, the pumped medium is compressed and transported to the outlet.

R5 vacuum pumps operate with recirculating oil lubrication. A downstream oil separator segregates sealing oil and pumped medium for efficient reuse of oil.

A non-return valve prevents the pumped medium from flowing back into the process after the vacuum pump is switched off.

With its impressive track record, our R5 vacuum pump has clocked an astounding 200,000+ hours of service with minimal maintenance since it was put into operation in 1988.
Remarkably reliable even under the strain of running two shifts a day (or more sometimes) for 14.5 hours - 4,422 annually for 34 years!

This resilient machine truly is the workhorse we can always count on.
