Impellerityypit, also known as impeller types, refers to the various designs and configurations of impellers used in centrifugal pumps and other fluid handling equipment. Impellers are rotating components that transfer energy to a fluid, causing it to move. The design of an impeller significantly influences the performance characteristics of a pump, including flow rate, head, efficiency, and NPSH (Net Positive Suction Head) requirements.

There are several types of impeller designs, each suited to different applications and fluid properties. Open impellers have no shrouds or casing, allowing for high flow rates but lower head. Semi-open impellers have shrouds on one side, providing a balance between flow rate and head. Closed impellers have shrouds on both sides, offering high head but lower flow rates. Backward-curved impellers are designed for high flow rates and low head, while radial impellers are used for high head and low flow rates. Mixed-flow impellers combine features of both backward-curved and radial impellers, providing a balance between flow rate and head.

The choice of impeller type depends on the specific requirements of the application, including the desired flow rate, head, efficiency, and NPSH. Engineers and designers must consider these factors when selecting an impeller type to ensure optimal performance and reliability of the fluid handling system.
