Refurbished Edwards EH-250 Booster Pump
The Edwards EH250 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.
