EH pumps with hydrokinetic drive

EH booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor to the pumping mechanism. The hydrokinetic drive offers the following advantages:

  • Pump down times cut by up to 50%
  • Reduced capital and operating costs
  • No pressure sensors, by-pass lines or valves
  • Can operate continuously at all pressures when used with a backing pump


EH booster pumps have universal voltage, air-cooled motors and are available with effective pumping speeds (at 50 Hz) of up to 3100 m3h-1. The pump bodies of the EH1200, EH2600 and EH4200 pumps are water-cooled.

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 (at atmospheric pressure) as it prevents motor overload. The EH booster pump therefore assists the pumping process from the start of pump-down. In comparison pumping systems with conventional, direct drive mechanical booster pumps (where the booster pump is switched on when the chamber pressure has been reduced to, typically, less than 10 mbar), the total evacuation time can be reduced by as much as 50%. 

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. Consequently, EH booster pumps are not damaged by sudden increases of inlet pressure and even by the entry of solid debris into the pump.

Important cost savings

When you use EH 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. Operation costs are reduced because EH booster pumps have smaller motors than direct drive pumps and, when operating at full speed, they use only a fraction of the rated power.
