The Norwesco 750 Gallon 45 Degree Cone Bottom Tank (SKU N-41495) is a 750-gallon white polyethylene cone bottom tank built for chemical dosing, batching, and full-drain handling where you cannot afford product sitting in the bottom of the vessel. The steep 45-degree cone discharges completely, so suspension chemicals, slurries, and settling solutions clear out instead of caking. This Norwesco cone tank stands 105 inches tall on a 52-inch by 52-inch footprint and carries a 1.5 specific gravity rating, which is the single most important number to check before you put a chemical in it.
Will it work for your application?
This is a cone bottom tank that requires a separate stand or structural support to hold the cone off the ground, so plan your installation around the 52.0 x 52.0 inch base. Filled with water the contents weigh 6,255 pounds; at the full 1.5 SG rating the tank is built to carry up to 9,382 pounds of contents, which is exactly the 6,255 lb water weight multiplied by 1.5. Use those weights when you size your stand, pad, and anchoring. If you are still deciding on capacity or how this fits your process, the Tank Sizing Calculator and Tank Sizing Guide will help you confirm the right cone tank for the job.
Chemical compatibility
This Norwesco tank is molded from polyethylene rated to 1.5 specific gravity. Our resin record shows HDLPE but is flagged for confirmation, so confirm whether your tank is HDLPE or XLPE before committing it to chemical service, since cross-linked and high-density linear resins do not behave identically with every chemical; call 866-418-1777 to confirm the resin grade for your unit. All compatibility below is drawn from our chemical-resistance data and is concentration and temperature specific, so verify your exact conditions before ordering. At the 1.5 SG rating, this tank suits the chemicals below at the noted concentrations, with the matching fitting and gasket materials:
| Chemical | Conc. | Fitting | Gasket |
|---|---|---|---|
| Acetic Acid | 60% | PP/PVC | EPDM |
| Aluminum Sulfate | 50% | PVC | EPDM |
| Calcium Chloride | 40% | PVC | EPDM |
| DEF (diesel exhaust fluid) | 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 |
| Ozonated Water | up to 10 PPM | PVC | EPDM |
DEF and urea storage are common uses here, both running EPDM gaskets with 316 stainless or PP/PVC fittings. Several chemicals are NOT suited to this 1.5 SG tank and require a higher 1.9 SG-rated cone bottom tank instead: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid (Viton), Hydrofluoric Acid (Viton), Hydrofluosilicic Acid (Viton), Hydrogen Peroxide (Viton), Peracetic Acid (316SS, Aflas), Phosphoric Acid (Viton), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (Viton), Sodium Thiosulfate, Sulfuric Acid (CPVC, Viton), and Zinc Orthophosphate. If your process involves any of these, order the 1.9 SG version of this cone bottom tank rather than this 1.5 SG unit, and call 866-418-1777 and we will point you to the right specific-gravity rating. Full details for every chemical are in our Chemical Compatibility Database.
The mistake to avoid
The most common error on a 750-gallon cone tank is matching the specific gravity of your chemical against the 1.5 rating of the tank instead of against water. A chemical heavier than 1.5 SG, such as sulfuric acid or ferric chloride and the others listed above, will overstress the wall even though the tank looks more than big enough by volume. Check the technical drawing on this page for fitting locations and confirm your gasket and fitting materials, EPDM, Viton, or PP/316SS depending on the chemical, before you plumb it.
