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 favorite pumps for applications where high pumping speeds over 3000m³/h are required in the pressure region of 0.01 to 50mbar. 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 reliables.
PERFORMANCE
Faster pump down time due to unique hydrokinetic drive. Larger displacement than equivalent competitor models.
SIMPLICITY
Continuous operation at all pressures. Simple installation with no need for pressure switches, bypass lines or variable frequency drives.
RELIABILITY
Automatic overload protection and reliable shaft seal design.
ROBUST OPERATION
Up to date technology – continued investment in design and technology improvements.
NO OIL SEAL RESERVOIR
No need to monitor and top up an external oil reservoir to protect the pump and ensure Atex compliance.
ATEX & FOMBLIN
Wide range of options available for every application.
