The 2500 Gallon 30 Degree Plastic Cone Bottom Tank from Snyder Industries holds 2,500 gallons in a white, 1.5 specific-gravity polyethylene body standing 125 inches tall on a 90 x 90 inch footprint. The 30-degree cone discharges thick or settling contents fully, which is why operators reach for this size when batching, mixing, or storing process chemicals that water-tank-rated poly cannot carry. Snyder rates the wall for liquids up to 1.5 specific gravity, and the supporting structure (stand sold separately) must be matched to the full load before you fill it.
Will it work for your application?
Plan around real loaded weight, not just gallons. Filled with water this tank carries about 20,850 lb; at the full 1.5 SG rating it reaches roughly 31,275 lb of contents. Those numbers drive your cone stand, pad, and anchoring — size them to the heavier figure if you are running a dense chemical. The tank body itself stands 125 inches tall before any stand is added, so compute total installed height (cone outlet below, manway above) against your building clearance. The technical drawing on this page shows the molded fitting layout: a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for inspection, cleanout, and gauging. That 18-inch fitting is vented, which matters for off-gassing chemical service such as DEF or sodium hypochlorite. Confirm those fitting locations and the 90-inch footprint against your existing piping and clearance before ordering, since a cone-bottom tank lives elevated on a stand. The Tank Sizing Calculator and Tank Sizing Guide help you reconcile capacity, footprint, and weight, and our 2500 Gallon 30 Degree Cone Bottom Tank buyer's guide walks through cone-angle tradeoffs against the 15-degree version.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. The resin is recorded as HDLPE but listed with a question mark, so confirm whether your unit is HDLPE or XLPE with us at 866-418-1777 before committing it to chemical service — crosslinked and linear poly resist different chemistries. Against the OEM chemical-resistance chart, and only at the concentrations and temperatures it specifies, this 1.5 SG tank is rated for 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). Match the fitting and gasket material to the chemical, since the right poly body paired with the wrong elastomer is the most common cone-tank mistake. Always verify your specific concentration and temperature on the OEM chart and our Chemical Compatibility Database before filling.
Chemicals that need a higher-SG tank
Several common process chemicals are too dense or aggressive for this 1.5 SG model and require a 1.9 specific-gravity tank instead — buying up front saves a return. Those 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. Gasket choice matters as much as the tank rating: hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, sulfuric acid, hydrogen peroxide, and sodium hypochlorite all call for Viton rather than EPDM (sulfuric also wants a CPVC fitting), while peracetic acid needs a 316SS fitting with an Aflas gasket. Call 866-418-1777 and we will spec the correct higher-rated tank and elastomer set.
This cone bottom tank ships LTL freight from Snyder's plant in Lincoln, NE, quoted live to your ZIP — get your number from the Freight Cost Estimator or call 866-418-1777. Because it ships from a single Nebraska plant, your freight cost depends heavily on distance, so run the estimate before you finalize. Questions on cone angle, fittings, or chemical service?
