Product Description

BSJ1200LC Hydrodynamic coupling 2590 m³/h 7.5kW Roots Vacuum Pump, Mechanical Booster Vacuum Pump



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.



​Technical Parameter :


Model Units BSJ600LC
Pumping Rate 50 Hz m³h-1 / Lmin-1 2590/43175

Max Inlet Pressure 50Hz Pa 8.0x103
60Hz Pa 6.7x103


Ultimate Vacuum


Pa/ mbar




Motor Power kW(hp) 7.5 (10.0)
Inlet -- ISO160
Outlet -- ISO100
Cooling Method Water-cooled
Lubricating oil specification   BSO-46
Gear Cover L 3.5
Hydraulic L 6.5
Shaft seal reservoir L 1.5
Ambient Temp. 5~35

Note: The value of 'Ultimate Pressure' in this sheet is measured by 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.
