Operating principle
The Busch R5 series works on the proven principle of oil-lubricated rotary vane vacuum technology. An eccentrically mounted rotor with vanes rotates inside the pump housing, creating continuously changing working chambers. As the chamber volume increases, the process air is drawn in, then compressed and expelled through the outlet valve.
The pump oil performs important functions for lubrication, sealing and heat dissipation and contributes to reliable and efficient operation. At the same time, the oil separation ensures that oil carry-over at the pump outlet is reduced. Depending on the model and version, different designs and options are available for various industrial process requirements.
The robust construction and the proven rotary vane principle enable high operational reliability, a long service life and reliable vacuum performance. The R5 series comprises numerous sizes and versions and is therefore suitable for a wide range of industrial applications, including packaging, vacuum lifting, pneumatic conveying, food processing and general vacuum processes.
