Edwards EH-4200 Booster Pump

Refurbished Edwards EH-4200 Booster Pump

The Edwards EH54200 Booster Pump features twin Roots lobes driven by a hydrokinetic drive mechanism that allows the pump to slip at high pressures to avoid stalling and provide pumping assistance from nearly atmospheric pressure. Unlike, the smaller EH250 and EH500, the EH4200 requires water cooling to the gear oil reservoir in order to remove heat. Like all blowers, it requires a suitable backing pump such as an Edwards GV600 or Stokes 412.

Note: Other motor voltages available upon request.
