White colour, 500m³/h Mechanical Booster Pump, Roots Pump BSJ150L
Description :
Roots vacuum pumps, also known as 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 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.
- A special shaft seal is used to achieve long, stable running without oil leakage.
- The BSJ-L series is made of all-aluminum alloy, a heat sink, corrosion-resistant, 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.

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 the inlet port must be 5~30℃. When the temperature is too low, keep it in an environment that is not prone to condensation.
