Product Description

Army Green , 500m³/h Mechanical Booster Pump,Roots Pump BSJ150L


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 oil-free intermediat seal,multiple sealed way to ensure the hight clean vacuum environment in the rotor chamber .
  • Advanced proceesing to ensure the good geometrical symmetry of the rotors,as well as low noise and long service life.
  • The whole rotors is made of aluminium alloy which has the charateristics of fast corrosion resistance and energy-efficient.
