EH 250,500,1200,2600,4200  Vacuum Punp

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 the following features:

-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 operation costs
-Aircooled motors - with water cooled options
-Quiet, minimum vibration

  The EH mechanical booster pumps, based on the simple Roots principle, remain the favorite 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 pumps must always be backed by another pump which can deliver against a high pressure differential to atmospheric pressure.
Operation 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.
