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.
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.
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.
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.
