ROOTS PUMP BSJ70L/150L/300L
Features:
· The use of oil-free intermediate seal, multiple sealed way to ensure the high clean vacuum environment in the rotor chamber.
· Advanced processing to ensure the good geometrical symmetry of the rotors, as well as low noise and long service life.
· Special shaft seal is used to achieve the long stable running without oil leakage.
· Direct-drive, aluminal pump body, compact structure, light weight, and small volume.
· The BSJ-L series is made of all-aluminum alloy, heat sink, corrosion resistance, and efficient energy saving. The BSJ-LC series is made of cast iron.
The uniqueliquid coupling method enables the pump to start directly under the atmosphere, which greatly reduces the time of puming.
