The Norwesco Polyethylene Stand for the 300 and 500 Gallon Norwesco Cone Bottom Tanks (MPN N-40574) is a vertical cone-bottom mixing vessel sized for batch chemistry, agricultural spray formulation, and aquaculture operations where residual liquid in a flat-bottom tank would cause carry-over contamination.
Design
- One-piece rotomolded shell — no welded seam at the cone-to-cylinder transition
- Integrated steel support stand sized to the tank — no field fabrication, no separate cradle to weld
- Conical bottom geometry ensures complete batch evacuation through the centered drain outlet
- Stand cross-bracing rated for the tank's full-load weight (water at 8.34 lb/gal × capacity for water service)
- Top manway sized for installation of overhead agitator, mixer, or sample-port assembly
Installation
The integrated steel stand sets directly on a level concrete pad with anchor-bolt mounting through the stand foot-plates. Confirm the pad bearing capacity meets the filled-tank load: at 500 gallons of water service, the filled assembly weighs approximately 4,170 lb (multiply by chemical SG for chemical service). Install a bottom-outlet shutoff valve before commissioning batch service. Plumb the drain to a containment sump or process catch.
Common applications
- Dairy clean-in-place (CIP) sanitizer staging and recovery
- Wastewater pH-adjustment and chemical-precipitation reaction holding
- Metal-finishing rinse-water collection and chemistry-recovery staging
- Industrial slurry handling where complete drain prevents sediment accumulation
- Pharmaceutical and nutraceutical batch-formulation and ingredient-staging service
- Process chemistry batch mixing in coatings, adhesives, and resin formulation
Compatibility & compliance
Tank shell meets ASTM D1998 for atmospheric polyethylene service. Steel stand finish (galvanized or powder-coat) is selected for outdoor or indoor environment — specify when ordering. Not rated for pressurized service, vacuum service, or chemical service beyond the OEM compatibility chart for the tank-shell resin.
