Mechanical Booster pumps

ZRS 250-4200

Based on the simple Roots principle, our mechanical booster pumps remain the favorite pumps 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.

Features you can rely on:

Pumping speed ZRS: 375-4985 m³/h

• Suitable for applications where high pumping speeds are required in the pressure region of 0.01 to 50 mbar/0.0075 to 37.5 Torr
• The ZRS pumps have a high quality, oil-free pumping mechanism
• The design of the shaft seals is optimized to ensure that no lubricants can migrate into the pumping mechanism
• The dynamically balanced rotors and precision ground gears contribute to the smooth, quiet operation of the pumps

The DRB Roots booster pump is air-cooled and with integrated bypass and offers peace of mind in food packaging applications.
