BOC Edwards EH-1200 Blower Vacuum Booster Pump - Rebuilt
For sale is a BOC Edwards EH-1200 Blower (Booster) Vacuum Pump, which are unique in utilizing a hydrokinetic fluid coupling to connect the electric motor shaft to the lobe rotor. The EH mechanical booster pump, based on the simple Roots principle, remain the favorite pump for applications where high pumping speeds are required in the pressures in the region of 0.01 to 10 mbar. This pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure. Operating at relatively low pressures, the mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable.
The priced listed above is for a BOC Edwards EH-1200 Rebuilt Blower (Boosters) Vacuum Pump only. We also sell mechanical and blower vacuum pump systems. Please call (505) 872-0037 for more information.
