  • Dual oil level monotoring systems; “Bullseye Sight Glass” and clear “Trico® Optimatic” constant level oiler.
  • Two heavy duty, back-to-back mounted, 7300 series, angular contact bearings, providing an industry leading L10 life in excess of 100,000 hours.
  • Largest shaft diameter (D) and shortest impeller overhang (L), resulting in the lowest “Shaft Flexibility Factor (L3/D4)” in the industry.
  • Flinger type lubrication system creates a constant oil mist cascading over the radial & thrust bearings, resulting in cooler running bearings than other manufacturers flooded lubricated bearings.
