Mechanical Booster Pumps

ZRS series

The ZRS mechanical booster pumps feature a unique hydrokinetic drive which provides efficient power transmission with benefits in economy, performance and compactness. These booster pumps are suitable for use with high differential pressures which allow the booster pump to be started at the same time as the backing pump, reducing total pump down times.

Pumps with hydrokinetic drive

ZRS booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor to the pumping mechanism. The hydrokinetic drive offers the advantages as pump down times cut by up to 50%. No pressure sensors, by-pass lines or valves. Reduced capital and operating costs.

Pump-down times cut by up to 50%

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

Automatic overload protection

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

Important cost savings

When you use ZRS mechanical booster pumps, you save money on installation and operation. Your capital costs are reduced as you do not need valves, by-pass lines and pressure switches, and you can use a smaller backing pump than with conventional drive booster pumps.

Boost your production

The ZRS mechanical booster pumps, based on the simple roots principle, remains the favourite 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.
