    1. DuraGlide™ Bearing System (blue areas in cutaway illustration) incorporates several components working together to eliminate seasonal freeze-up.
    2. Powerful motor provides years of trouble-free operation.
    3. One-piece, high-nickel stainless steel stator can isolates the stator from system fluid and maintains precision bearing alignment for longer bearing life.
    4. Carbon bearings, diamondlike ceramic shaft and generous clearances are more resistant to lime, chloride and oxide build-up.
    5. Face plate and rotor sleeve feature corrosion resistant stainless steel construction for longer life.
    6. Self-cleaning particle shield protects the shaft and bearings from system start-up debris.
    7. Stabilized, heat resistant, non-ferrous impeller, its closed design improves operating efficiency.
