The PolyChem VGRP pump is a fiberglass, vertical immersion, open impeller type pump designed for corrosive wet pit applications in waste handling and chemical transfer. The PolyChem VGRP is available in seven sizes, with single-piece columns in 3 ft to 18 ft lengths.
- Applications:
Water Treatment, Shipping, Volatile Organic Compounds, Waste Processing, Acid Transfer, Auxiliary (chemical), Auxiliary Services (power), Bleach Chemical (pulp and paper), Caustic and Chlor-alkali, Chemical and Liquor (pulp and paper), Coatings (pulp and paper), Cooling Water (metals), Leaching Acid, Plating, Galvanizing and Other Coatings, Polymers, Renewable Fuel Production, Solvents - Industries:
Water Resources, Chemical Processing, General Industries, Pulp and Paper, Power Generation, Primary Metals, Mining
Engineered Polymer Composite Construction offers cost-effective corrosion-resistance and is lightweight, non-galling, non-sparking, and non-conductive.
Unitized Case with Integrally Molded Flanges at the suction and discharge nozzles are fully gusseted to ensure structural soundness under extremes of applied nozzle loads.
Externally Adjustable, Semi-Open Impeller is inherently balanced and provides consistently high efficiencies while minimizing maintenance.
Shaft/Bearing System operates well below the first critical speed, resulting in 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 but generously sized and thick in cross-section for strength and rigidity.
