Pump Impeller Structure

The structure of a pump impeller typically includes blades, an impeller body, and bearings. The blades are the key component of the impeller; their shape, number, and arrangement directly affect pump performance. Generally, blade shapes can be divided into straight blades and curved blades. Straight blades are mainly used in pumps with low flow rates and high heads, while curved blades are suitable for high flow rates and low heads. The number of blades is generally between three and six; different numbers affect the pump's flow rate and head characteristics.
