Description
The Hale F17 impeller key is a specific type of key used to secure an impeller onto a shaft. Impellers are the rotating components in centrifugal pumps that create the centrifugal force to move fluids. The keyway is a slot machined into the shaft, and the impeller key is a small wedge-shaped piece of metal that fits into the keyway. The impeller is then pressed onto the shaft, and the key prevents the impeller from slipping or rotating on the shaft.
