Edwards EH-500 Booster Pump

Refurbished Edwards EH-500 Booster Pump

The Edwards EH500 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. Like all blowers, it requires a suitable backing pump such as an Edwards E2M40 and E2M80.

Note: Other motor voltages available upon request.
