    Technical Data

    • Engineered Polymer Composite Construction offers cost-effective corrosion-resistance, is lightweight, non-galling, non-sparking, and non-conductive.
    • Unitized Case with Integrally Molded Flanges at the suction and discharge nozzles, fully gusseted for structural soundness.
    • Externally Adjustable, Semi-Open Impeller provides consistently high efficiencies and minimizes maintenance.
    • Shaft/Bearing System operates below the first critical speed for less shaft whip and longer bearing life.
    • Bearings can be lubricated by external flush or self-lubricated by the pump fluid.
    • Single-Piece Column is lightweight, filament-wound, reinforced fiberglass composite for strength and rigidity.

    Advantages

    • Lightweight and corrosion-resistant due to engineered polymer composite construction.
    • High efficiency and minimal maintenance with externally adjustable impeller.
    • Long bearing life with low shaft whip and flexible lubrication options.
    • Robust construction with unitized case and reinforced single-piece column.
