Impeller Blades

Impeller blades are blades that are integral to an impeller (a rotor used to increase the pressure and flow of a fluid). An impeller is a rotating component of a centrifugal (uncentered) pump which works by transferring energy from the fan motor to the fluid that is being pumped by the accelerating blades.

What are impellers?

Impellers are usually short cylinders with an open inlet (called an eye) to accept incoming fluid.

Uses for impellers

Medical devices

Impeller blades are used in ventricle assist devices (devices used for assisting cardiac circulation) which augment or fully replace cardiac function.

Air pumps

Air pumps use impeller blades to help move air through a system, for example within blast furnaces, ventilation systems, and superchargers for internal combustion engines.

Features of impeller blades

Impeller blades are typically made out of cast stainless steel material. In many cases they have five propellers which allows them to have maximum rotation effect to transfer energy efficiently.
