Structural Features

① The impeller has a back blade or balanced hole structure to balance the axial force, and the residual axial force is absorbed by the bearing.

② The bearing is lubricated with thin oil, and the constant oil cup and visual oil window are used to control the lubricating oil level.

③ A bushing is used to protect shaft to prevent it from medium contact. This structure avoids shaft to be corrosive by medium. It can improve the service life and reliability of the shaft.

④ It is not necessary to dismantle the pipes at inlet and outlet, and the motor by the rear drag design. The entire rotor component can be pulled out from the rear for easy maintenance.
