Roots Vacuum Pump

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.

• The BSJ-L series are made of all-aluminum alloy, heat sink, corrosion resistance, and eficient energy saving. The BSJ-LC series are made of cast iron.The unique liquid coupling method enables the pump to start directly under the atmosphere, which greatly reduces the time of pumping.

• Compact structure, light weight, and small volume.
