Product Description

White , 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 intermediate seal, multiple sealed way to ensure the high 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.
  • Special shaft seal is used to achieve the long stable running without oil leakage.
  • 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 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.

Motor Power kW(hp) 2.2(3.0)
Inlet -- VG80
Outlet -- VF80
Cooling Method Water cooled
Oil Need L 1.6
Ambient Temp. 5~40
Weight -- BSO-46


Note: The value of 'Ultimate Pressure' in this sheet is measured by the Pirani gauge when the Baosi special pump oil is used, and the value should be 4x10-3 if the Mcleod gauge is used.

         The cooling water temperature of inlet port must be 5~30℃ When the temperature is too low, keep it in an environment that is not easy to condense.
