．Well-constructed, low noise during operation, can be high temperature and pressure operated
．Can select mechanical seal during high pressure operation

．Mechanical seal coupled with oil pressure system, using hydraulic lubricant and cycle cooling, long durable than general mechanical seal.

．Also offers oil pressure drive

Advantages of oil pressure drive:

．Total flame-proof reactor tank

．Low-noise operation
．The bigger the viscosity change is, the more it protects the machinery and mixer equipment during reaction.

．Can oil pressure automatic as overload, it protects the machinery and mixer equipment during reaction.

．Stepless adjustment, the rotation speed is adjustable and readable on control-panel.
