ZRS Vacuum Booster Pump

Mechanical Booster Pumps

ZRS 250-4200 series

Rugged and corrosion resistance and an advanced shaft-seal technology with no oil contamination of the process chamber

Pumps with hydrokinetic drive

ZRS booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor to the pumping mechanism. No pressure sensors, by-pass lines or valves

Quicker pump-down times

The hydrokinetic drive allows the booster pump to be started at the same time as the backing pump as it prevents motor overload, assisting the pumping process from the start of pump-down

Automatic overload protection

The hydrokinetic drive automatically varies the rotational speed of the pump, protecting the motor from overload and preventing over-heating. This allows the pump to operate with high-pressure differentials

Cost savings

Save money on installation and operation as capital costs are reduced because you do not need valves, by-pass lines and pressure switches

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:

  • Vacuum packaging
  • Vacuum distilation
  • Space simulation

  • Drying and de-gassing
  • Thin film coating
  • Vacuum impregnation

  • Vacuum metallurgy
  • Low density wind tunnels
  • Freeze drying
