Stainless Steel Closed Impeller Casting
Closed impellers have a back and front wall around the vanes or the Blades, to increase strength. Closed Impeller are used primarily in larger Centrifugal pumps. we use Low pressure investment casting to develop the impeller.
Semi-Closed impellers have a back wall that adds strength to the impeller. Semi-closed impellers are usually used with liquids or products that have solids. Reduced efficiency is a common problem with semi-closed impellers, but the ability to pass solids is an important trade-off.
According to the structure, it can be divided into binary impeller and ternary impeller, and ternary impeller is divided into open ternary impeller or closed ternary impeller.
According to the purpose, it can be divided into compressor impeller, water pump impeller (nuclear pump), power generation impeller.
According to the material, it can be divided into: KMN, FV520B, Q345E, TC4, 06Cr13Ni5Mo, etc.
Manufacturing capacity:
