hero title image

The design of the Marine style mixing impeller has its roots in the marine propulsion industry, and is also commonly used in the mixing industry. It is the most-effective axial pumping impeller at higher mixing speeds, and is often used with direct drive mixers operating at 900-1800RPM. Fusion’s Marine props are investment- CAST 316 stainless steel, and are bored to accommodate common shaft diameters.
