EH MECHANICAL BOOSTER PUMPS

Product catalog summary

Overview
The EH Mechanical Booster Pumps by Edwards are designed to enhance productivity with their unique hydrokinetic drive, allowing operation from atmospheric pressure for fast pump down times. These pumps are easy to install, requiring no pressure switches, bypass lines, or variable frequency drives. They are reliable, featuring automatic overload protection and a robust shaft seal design, and are widely used in industrial and chemical markets.

Specifications
The EH pumps are available in sizes ranging from 250 to 4200 m³/h displacement. Key specifications include:

Displacement at 50 Hz: 310 to 4140 m³/h
Displacement at 60 Hz: 375 to 4985 m³/h
Inlet connections: ISO63 to ISO250
Pressure differential: 0-180 mbar at 50 Hz, 0-150 mbar at 60 Hz
Weight: 69 to 481 kg
Motor power: 2.2 to 11.0 kW
Oil capacity varies by component
Water cooling required for larger models

Applications
These pumps are suitable for a variety of applications including semiconductor processing, vacuum distillation, vacuum packaging, steel degassing, thin film coating, vacuum metallurgy, low density wind tunnels, space simulation, vacuum impregnation, oil drying and degassing, pharmaceutical freeze drying, and CO2 lasers.
