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.
