2500 Gallon 30 Degree Cone Bottom Tank with Poly Stand

The Norwesco 2500 Gallon 30 Degree Cone Bottom Tank with Poly Stand (SKU N-40672) is a closed-top polyethylene tank built for full-drain chemical batching and process work.It holds 2,500 gallons in a white poly tank that stands 116" tall on a 99"-diameter footprint, drains through a 30-degree cone to a 2" outlet, and fills through a 16" lid.The tank ships empty at 889 lb, carries a 1.5 specific gravity rating, an FDA-approved resin, and a 120 F / 48 C maximum service temperature.If you have been searching "2500 gallon cone bottom" or a Norwesco degree-cone stand tank, this is the closed-top version that empties itself and lets your product settle to the point.

Does this tank work for your job?

The 30-degree cone routes solids and liquid to the center 2" outlet so you get near-complete drainage without a manual sump — useful for settling, dosing, and mix-and-drop batching.Size the load before you buy: 2,500 gallons of plain water weighs 20,850 lb, and at the tank's full 1.5 SG rating the maximum rated contents weight is 31,275 lb sitting on that 99"-diameter poly stand.Confirm your slab or pad can carry the loaded weight and that the 116" overall height clears your fill point and roofline.The 16" lid sets your top-fill and access opening, and the 2" outlet sets your plumbing and pump sizing.Run your working volume and turnover through the Tank Sizing Calculator and the Tank Sizing Guide before finalizing fittings, and see the technical drawing on this page for the cone, outlet, and stand geometry.

Chemical compatibility

This is a polyethylene tank rated to 1.5 specific gravity.Our records tentatively show linear polyethylene (HDLPE), but this is unconfirmed — we will verify HDLPE vs XLPE with you before chemical service, since crosslinked and linear polyethylene resist different chemicals.Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; verify your exact chemical, concentration, temperature, and the fitting and gasket materials before committing.Within the 1.5 SG rating this tank suits Acetic Acid (60%) with PP or PVC fittings and EPDM gaskets, Aluminum Sulfate (50%), Calcium Chloride (40%), Ferrous Sulfate (20%), Magnesium Chloride (30%), and Sodium Carbonate (30%) — all on PVC fittings with EPDM gaskets — plus Ozonated Water up to 10 PPM (PVC/EPDM).For DEF at 32.5% use 316SS fittings with EPDM gaskets, and Urea Solution (50%) runs on PP/PVC with EPDM; both only need a 1.5 SG rating, which this tank exceeds.

The mistake to avoid: specific gravity

The most expensive error on a cone-bottom chemical tank is under-rating specific gravity.This tank is a 1.5 SG unit, so heavier chemicals need a higher-SG tank — do not put them in this one.Sulfuric Acid (98%) needs CPVC fittings with Viton, Hydrochloric Acid (37%), Ferric Chloride (50%), Sodium Hypochlorite (<16.5%), Hydrogen Peroxide (50%), and Phosphoric Acid (85%) all run PVC with Viton, Peracetic Acid (30%) specifically calls for 316SS fittings with Aflas, and Ethylene Glycol (100%) and Potassium Hydroxide round out the list — all requiring a 1.5 SG tank.Match the gasket to the chemical, not just the fitting.If your product is on this heavier list, call 866-418-1777 and we will spec the correct higher-SG cone-bottom unit for you.Full details are in our Chemical Compatibility Database, and the 2500 Gallon Cone Bottom Buyer's Guide walks through the sizing and fitting decisions in order.
