Paddle Blades

A paddle blade is the most basic impeller type but is still commonly used. A paddle bladed impeller is also a radial bladed impeller but does not have a shroud or backplate

Paddle bladed efficiency is also the lowest of the range reaching efficiencies in the low 60%.

The reason they are used so often is because they are so versatile and are the best type of blade for extreme dirt/material conditions or when the material passing thro them is sticky. Pressure capabilities are good but a paddle blade is seldom used for high volumes.
