8/6E-AH Slurry pump expeller EAM028A05

Tobee® EAM028A05 expeller is comply with 8/6E-AH & 8/6E-AHR Slurry Pumps, It is combined with the expeller ring to form the dynamic seal of the slurry pump. It is one of the three types of shaft seals of the slurry pump.

And the expeller can not only play a role in sealing, but also play a role in reducing the axial force. If the expeller is installed, the direction of the pressure differential force acting on the expeller by the liquid is opposite to the pressure differential force acting on the impeller, so that part of the axial force can be offset and the bearing life will be prolonged. The standard material of the expeller of the slurry pump is generally cast iron or ductile iron, and it can also be made of A05 as the wetted part material according to customer requirements. In recent years, most customers prefer A05 high-chrome alloy material when purchasing.

When the expeller of the slurry pump is working, the main shaft of the slurry pump rotates together, and the liquid in the expeller will also rotate together. The rotating liquid will generate an outward centrifugal force, which on the one hand resists the flow to the mechanical seal. Liquid reduces the pressure at the mechanical seal. On the other hand, it prevents the solid particles in the medium from entering the friction pair of the mechanical seal, reducing the wear of the mechanical seal grinding block and prolonging its service life.
