EH Mechanical

Booster Pumps

The EH mechanical booster pumps feature the unique hydrokinetic drive, providing an efficient power transmission with benefits in economy, performance and compactness, while making them extremely robust.

250 - 4.200 m³/h

Larger displacement that equivalent competitor models, faster pump-down times

From Atmospheric pressure

Thanks to the unique hydrokinetic drive, can operate in the full pressure range from atmosphere to ultimate

Simple Installation

No need for pressure switches, bypass lines or variable frequency drives.

Reliable

Automatic overload protection and reliable shaft seal design

Atex & Fomblin versions

PFPE and fully compliant ATEX versions available

Pump-down times cut by up to 50%

Our patented hydrokinetic drive allows the booster to operate from atmospheric pressure. The total evacuation time can be reduced by as much as 50% as the booster can assist in pump down from the very beginning, saving you valuable process time. The HK drive allows for the pump to automatically slow down at higher pressures preventing the pump from over-heating.

Robust operation even for harsh duties

Our proven shaft seal design helps protect the pumping mechanism and gearbox from cross-contamination with even your harshest applications. EH booster pumps are not damaged by sudden increases of inlet pressure helping you to avoid unscheduled breakdowns and improve overall process performance.

Automatic overload protection

The varying rotational speed of the pump protects the motor from overload and over-heating for longer-life operation. The built-in hydrokinetic drive automatically allows the pump to operate with high-pressure differentials, making this a highly flexible workhorse.

Simplicity with reduced installation costs

With an EH booster pump, you do not need by-pass lines, pressure switches or inverters reducing the overall installation costs. With a reliable and robust hydrokinetic drive, you get the advantage of a simple and easy installation with minimal maintenance.
