Edwards Vacuum EH Mechanical Booster Pump EH500T3

The EH500T3 mechanical booster pump has been certified for use in Ex II 2G c IIB T3 classified areas. The temperature classification of the mechanical booster pump is based on the outlet pressure of the pump being maintained below the critical backing pressure of 10 mbar (1 x 103 Pa) at zero flow. The EH mechanical booster pump, based on the simple Roots principle, remains the favourite pump for applications where high pumping speeds are required for 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.
