Product Description

1200L/s (4140m³/h) 11kW Mechanical Roots Pump, Booster Pump BSJ1200L



Description :


Roots vacuum pumps, which are also called Roots blowers, are rotary plunger-type pumps where two symmetrically shaped impellors rotate in opposite directions inside the pump housing.




  • The use of an oil-free intermediate seal, multiple sealed ways to ensure a 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.
  • The whole rotor is made of aluminum alloy which has the characteristics of fast corrosion resistance and is energy-efficient.
