316 Lost Wax Investment Stainless Steel Casting Impeller Casting

We have a professional melting mold casting technology team to provide a complete impeller and valve casting solution. Provide customized products and OEM services to save you cost and create value. The service life of our stainless steel impeller can be guaranteed and it is not easy to damage. Even after using it for a period of time, it can still maintain stability to prevent rust. In addition, stainless steel castings can customize different specifications and sizes according to different uses. These cast stainless steel impellers are not only widely used in pumps, but also in certain industrial equipment. Due to stainless steel casting, the strength of the leaf wheels is always higher than other materials.

There are mainly the following three types of impeller casting:

Closed impeller: consisting of blade and front cover. Closing the impeller is more efficient and more difficult to manufacture. It is most commonly used in centrifugal pumps. It is suitable for cleaning liquid with small viscosity without particles without particles

Semi -open leaf wheel: Generally, there are two structures: one is the front half of the leaf wheel, which consists of the rear cover and blade. The impeller of this structure is relatively low. In order to improve efficiency, a adjustable gap sealing ring is needed. The efficiency is basically the same as that of the closed impeller, and the leaves have a sealing function of the posterior blade or auxiliary impeller in addition to the transmitting liquid. The semi -open leaf wheel is suitable for transporting liquid containing suspended solids, fibers. In recent years, the impeller of the semi -switch in the centrifugal pump has gradually increased the oil refining and chemical industry, and it is used to transport clean water and similar liquids.

Open leaf wheels: only with blade and blade reinforcement, and the impeller without front and rear cover. The number of open leaves is 2-5. The leaf wheels of the pump are inefficient and less applied. It is mainly used to transport high viscosity and slurry liquid.
