Description

160CFM (280m³/h) 50Hz/60Hz 0.75kW 2Poles Mechanical Booster Pump,Roots Pump BSJ70L

Description :

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

Characteristics:

  • The use of an oil-free intermediate seal, multiple sealed ways to ensure a hight 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 rotors are made of aluminium alloy, which has the characteristics of fast corrosion resistance and energy-efficient.

Note:

*1 The value changes depending on the performance of the fore pump. The above data is obtained when the pump is used in combination with a standard fore pump.

*2 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.

Applications

  • Semiconductor Fabrication
  • LED & Display Manufacturing
  • Vacuum Heat Treatment
  • Physical Vapor Deposition (PVD)
  • Vacuum Distillation & Drying
  • Food Preservation & Processing
  • Vacuum Packaging
  • Scientific Research

Typical System Configurations

  • Roots + Rotary Vane Pump
    Commonly used in general industrial applications (e.g., packaging, heat treatment) to achieve medium vacuum (10⁻¹–10³ Pa).
  • Roots + Screw Pump
    Preferred for dry processes (e.g., semiconductor etching) to avoid oil contamination, with screw pumps serving as the backing stage.
  • Roots + Turbomolecular Pump
    Used in UHV systems (10⁻⁶ Pa or lower) for research and aerospace, where roots pumps pre-evacuate chambers before turbopumps take over.
