ZRS series – Designed to boost your production
The ZRS mechanical booster pumps, based on the simple roots principle, are ideal 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.
These pumps have a high quality, oil-free pumping mechanism and offer a quiet, vibration free operation, Rugged and corrosion resistance and an advanced shaft-seal technology with no oil contamination of the process chamber.
The ZRS Mechanical Booster pump is ideally suited for:
