Tobee® Expeller C028HS1A05 is for the 4/3C Hi-seal slurry pump, It is also one of the important parts of the slurry pump, and be combined with the decompression cover to form the dynamic seal of the slurry pump. It is one of the three types of shaft seals of the slurry pump. Below we will briefly introduce the expeller of the slurry pump:
The standard material of the expeller of the slurry pump is generally gray iron or ductile iron, and it can also be made of A05 and A05A as the flow-through part material according to customer requirements. In recent years, most customers prefer AO5 high-chromium wear-resistant alloy material when purchasing.
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 power seal composed of the expeller and the decompression cover is cheap and easy to maintain
But the expeller sealing system also has disadvantages
1. Part of the energy is consumed on the expeller, generally about 3%
2. The expeller seal generally needs to cooperate with the parking seal, but the service life of the parking seal is relatively short
