Compact vacuum pump offers greater energy saving potential

20 August 2023

A new rotary vane vacuum pump from Busch – the R5 RA 0520 A – is said to increase energy savings by up to 25%, thanks to an optimised compression ratio, pump stage dimensions, and oil discharge path.

The pump features a compact and hygienic design, reduced heat emissions, and enables faster and easier maintenance. The optional ECOTORQUE variable speed drive (VSD) provides up to 50% additional energy savings and a 20% increase in pumping speed. It allows pumping speeds to be adapted to the exact requirements of any process. As a result, additional energy savings of up to 50% and a 20% increase in pumping speed can be achieved.

Compared to the previous generation, the R5 RA 0520 A also has a 20% smaller footprint, is 25% lower in height, and the absence of external piping improves leak tightness.
