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.
- Volumes up to 27 m³/sec
- Static pressure to 4 kpa
- Temperatures up to 430˚C
- Flat Radial Blades handle dirty air and materials without build-up
- Stable performance from shut-off to wide open; operates without pulsation over a range of duties.
- Rugged, continuously welded heavy steel plate construction
A choice of wheels to meet specific application needs
- WF – wheel handles fibrous materials.
- LS – wheel is for viscous material that would build up on other wheels.
