Edwards EH Mechanical Booster Pumps

Models: EH250, EH500, EH1200, EH2600, EH4200 | Manufacturer: Edwards

The Edwards EH Booster Pump range offers high-speed mechanical boosting for demanding vacuum applications, with five models available, ranging from EH250 to EH4200. The EH series utilizes hydrokinetic drive technology and operates at atmospheric pressure. This allows for rapid pump-down without the need for pressure switches, bypass lines, or variable frequency drives. The range is available with different cooling and oil configurations to suit application requirements.
