ROTARY VANE VACUUM PUMPS,TWO-STAGE, RZ9

Vacuubrand rotary vane pumps encompass one and two stage pumps with throughputs from 2 to 9 m³/h.
Typical rotary vane pump applications include, use as a backing pump for turbomolecular pumps but also serve in diverse chemical laboratory applications.
Features and important characteristics: high water vapour tolerance, vacuum tight pumping mechanism when switched off, high performance gas ballast mechanisms. These increase the overall performance potential of these pumps, the service life of mechanical parts, increase oil-change intervals and reduce maintenance overheads.
