BSJ70L 165CFM (280m³/h) 50Hz 0.75kW 2Poles Mechanical Booster Pump,Roots 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.

Characteristics:

• 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 :

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.
