1. Plastic sleeve isolates the stainless steel shaft from the fluid being pumped.
2. O-ring seals between the plastic sleeve and the impeller, and betwwn the impeller and the locknut, assure no metal contact with solution.
3. The retractable front bearing can be pulled back n parallel bars for easy seal inspection, reduced maintenance and assuring perfect alignment
4. Heavy duty, self aliging bearings widely spaced on the shaft, fo maximum stability and long seal life.
5.The relatively short, large diameter stainless steel shaft with generous radii significantly reducesmstress concentrations and avoids the potential for the impeller.
6. Camlock bearings are utilized to allow easy adjustment of the impeller.
7. Heavy sectioned static casing O-ring prevents leaks and blow outs.
8. Key driven, dynamically balanced molded impeller design with stainless steel imbedded insert ensures positive drive provides additional rigidity to impeller at higher temperatures and pressures, and prevents damage in case of reverse rotation Semi-open or closed impellers are available.
