1. Features
The rotor and rotor are used to keep the same position between rotor and rotor because of the opposite friction between rotor and rotor

The support adopts reliable anti clearance structure, and the rotating parts make detailed dynamic balance;

therefore, the operation is stable, the noise is low, and the use is more reliable;

 it can run for a long time under high pressure difference;

the imported oil seal is used in the dynamic sealing part to control the runout of the shaft seal within 0.02mm;

 therefore, the shaft seal is reliable.
