ZRS 250-4200

ZRS, Vacuum booster pump

The ZRS mechanical booster pumps, based on the simple roots principle, remains the favorite pump for applications where high pumping speeds are required for pressures in the region of 0.01 to 50 mbar.
This pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure. Operating at relatively low pressures, the mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable.
