Cornell Pump sees thousands of impellers machined and balanced in the factory every year. Some are considerably bigger than others, though. This solids handling impeller is pictured next to a bronze impeller often used in our agricultural pumps for size comparison. It started out as 28″ in diameter (before trimming) and 19 1/4″ tall. Also notice the 12″/ 30cm ruler in front of the impeller for reference.
Cornell makes impellers that can handle more than a 10″/ 26cm solid, with flows over 38,000 GPM/ 8600 m3/h. Many of our brochures list types of impellers available, and all of our data sheets show impeller materials and trims available. You can find most of our brochures here on the Cornell Website.
