An impeller blade is a component of an impeller, which is a rotating device designed to transfer energy from a motor to a fluid (liquid or gas), increasing its pressure and flow rate.

Functions:Convert rotational energy into fluid motion.

Increase pressure and velocity of the fluid.

Guide the fluid in a specific direction (axial, radial, or mixed).

Types of Impeller Blades:Open – No shroud; easy to clean, less efficient.

Semi-open – Partially covered; balances efficiency and cleaning.

Closed – Fully shrouded; most efficient, harder to clean.

Design Considerations:Blade angle and curvature – Controls flow direction and velocity.

Number of blades – Affects flow smoothness and efficiency.

Material – Depends on fluid type (corrosive, abrasive, etc.), e.g., stainless steel, bronze, plastic.

Thickness and strength – Must withstand centrifugal forces and pressure.
