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.
