The Edwards EH 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.

EH2600 Mechanical booster pump
The EH mechanical booster pumps feature the unique hydrokinetic drive, providing an efficient power transmission with benefits in economy, performance and compactness. The hydrokinetic drive provides pump down times cut by 50%, when compared with direct drive pumps, no bypass lines or pressure switches required, universal voltage motors, reduced capital and operating costs, air cooled motors – with water cooled options, and quiet, minimum vibration.
The EH mechanical booster pumps, based on the simple Roots principle, remain the favourite pumps for applications where high pumping speeds over 3000 m3h‑1/1776 ft3min-1 are required in the pressure region of 0.01 to 50 mbar/0.0075 to 37.5 Torr. These 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.
Technology
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:
