The Norwesco 1500 Gallon 45 Degree Cone Bottom Tank (N-43854) is a white polyethylene tank built for full-drain chemical processing, batching, and metering. With a 1.5 specific gravity rating, it handles dense liquids that a standard 1.0-rated water tank cannot, and the steep 45-degree cone bottom evacuates solids and sediment that would otherwise settle and stratify in a flat-bottom tank. Because the cone cannot rest on a flat slab, this cone tank must sit on a stand that clears the cone for full gravity discharge - so the 112 inch height listed here is the tank alone and does not include the stand or your overhead clearance for fill and venting. The footprint is 72 x 72 inches.
Will it work for your application
This 1500 gallon cone bottom tank holds roughly 12,510 pounds when full of water at SG 1.0. At its full 1.5 SG rating it carries up to 18,765 pounds of contents, so the supporting steel or poly stand and the slab beneath it must be engineered for that loaded weight, not just the gallons. The 1.5 rating is the line that decides whether a chemical is safe to store here at the listed concentrations. The 1500 gallon figure is nominal capacity; confirm your true working volume and the required stand clearance against the technical drawing on this page, which also shows fitting locations and overall dimensions. If you are unsure how this size fits your throughput or footprint, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide.
Chemical compatibility
This tank is molded from polyethylene at a 1.5 specific gravity rating. Norwesco does not always publish whether a given cone tank is linear or cross-linked, so confirm the resin type for your specific unit (HDLPE vs XLPE) before placing it into chemical service, since that distinction can change which chemicals are appropriate. At the 1.5 SG rating, the following are compatible at the listed concentrations: Acetic Acid 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate 50% (PVC, EPDM), Calcium Chloride 40% (PVC, EPDM), DEF 32.5% (316SS, EPDM), Ferrous Sulfate 20% (PVC, EPDM), Magnesium Chloride 30% (PVC, EPDM), Sodium Carbonate 30% (PVC, EPDM), Urea Solution 50% (PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). This tank does not ship with chemical-rated fittings or gaskets - match the fitting and gasket material to your chemical exactly as listed above, and always verify against the OEM chemical-resistance chart for your specific concentration and temperature before filling. Call 866-418-1777 if you need help speccing the right fitting and gasket package.
Chemicals that need a higher-SG tank
Several common process chemicals exceed what a 1.5 SG tank should hold and require a 1.9 SG-rated tank instead. These include Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Elastomer selection shifts within this group as well: most use EPDM gaskets, but Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric require Viton, while Peracetic Acid requires Aflas - and Sulfuric steps fittings up to CPVC. Do not store any of these in this 1.5 SG tank; if your service is on this list, call 866-418-1777 for the 1.9 SG-rated equivalent. Check the full Chemical Compatibility Database before you commit, since the most common and costly mistake on cone tanks is matching the chemical to the cone geometry while overlooking the SG rating.
This tank ships LTL freight from the Norwesco plant in St. Bonifacius, Minnesota, with freight quoted live to your ZIP code. Freight class and cost are driven by the crated tank weight and the 72 x 72 inch footprint, so run your delivery address through the Freight Cost Estimator before committing, or call 866-418-1777 to talk through fittings, stand requirements, and freight.
