Classification:
1. Closed impeller: consists of blades and front and rear cover plates. The closed impeller is more efficient and difficult to manufacture. It is most used in centrifugal pumps. It is suitable for conveying clean water, solution and other clean liquids with low viscosity without particles.
2. Semi-open impeller: Generally, there are two structures. One is the front semi-open type, which is composed of a rear cover and blades. The efficiency of the impeller of this structure is low. In order to improve the efficiency, it needs to be equipped with an adjustable gap seal ring. The rear half-open type is composed of a front cover and blades. Because the same sealing ring as the closed-type water pump impeller can be applied? The efficiency is basically the same as that of the closed-type impeller. In addition to transporting liquid, the blades also have: back blades or auxiliary impellers Sealing function. The semi-open impeller is suitable for conveying liquids containing suspended solids such as solid particles and fibers. The semi-open impeller is less difficult to manufacture, lower in cost, and highly adaptable. In recent years, it has been increasingly used in centrifugal pumps for refining and chemical industries, and is used to transport clear water and liquids similar to clear water.
3. Open impeller: an impeller with only blades and blade stiffeners, without front and rear cover plates. The number of open impeller blades is less than 2-5. The pump impeller is low in efficiency and has fewer applications. It is mainly used to transport liquids with higher viscosity and slurry liquids.
