Click：Principle of Roots Vacuum Pump

The motor of this pump series is upgraded to a permanentmagnet variable-frequency water-cooled vacuum motor, whichinherits all functions of the original pump while deliveringenhanced advantages:

1、Dynamic seals are eliminated to completely eradicate oil leakage risks. The motor and vacuum pump form a fully enclosed chamber, realizing zero leakage of the pump unit;

2、Supports variable frequency regulation, enabling precise control in accordance with on-site operating load;

3、High efficiency and energy saving, complying with China' s Class 1 energy efficiency standard;

4、Significantly reduced outline dimensions, greatly saving installation space;

5、Adopts variable-frequency starting(inverter required), ensuring stable and reliable operation。
