Propeller Styles
3-Blade MP Style
The 3-blade MP style propeller is a multi-purpose propeller designed for mixing, blending, agitating and liquid movement of all kinds. The propeller incorporates a modified semi-elliptical design, which was developed from years of experience and research, and is considered the standard by which propellers are judged. The MP style is available in "full" blade tip for open liquid applications or a "clipped" tip design for improved efficiency in a duct. The MP style is offered standard in a 3-blade design (both super and square pitch) but also available in a 4-blade design for some sizes.
2-Blade Weedless
The 2-blade weedless propeller is commonly used on aeration and mixing equipment employed in water and wastewater treatment applications. The weedless propeller was designed by Quality Castings to be utilized in applications where solids and other stringy material may be encountered. The non-fouling design eliminates material build-up on the propeller, mitigating equipment failure. The weedless propeller is available in a "full" blade tip design for open liquid applications, or a "clipped" blade design for improved efficiency in a duct.

4-Blade Kaplan Style
The 4-blade Kaplan style propeller was designed for moving liquid in a duct. The propeller is commonly utilized by low head pumps and mixers positioned in a duct.
