Mechanical Booster Pumps

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. 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.

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.

Pumps with hydrokinetic drive
ZRS booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor tothe 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.
