The Enduraplas 1100 Gallon White Cone Bottom Tank is built for full-drain chemical batching, mixing, and dosing where you need every drop to evacuate the bottom outlet. This is a true cone bottom tank from Enduraplas, molded in natural white polyethylene with a 1.9 specific gravity rating, standing 103 inches tall on a 60 x 60 inch footprint. The natural white translucence lets you eyeball your liquid level through the wall, and the 1.9 SG rating is the headline spec: it means this vessel is engineered to hold dense chemicals far heavier than water, which is exactly what separates a chem-service cone tank from a plain water tank.
Will it work for your job
At 1,100 gallons, this tank holds 9,174 pounds when filled with water. Because it carries a 1.9 SG rating, its maximum rated contents weight climbs to 17,431 pounds, so a stand and anchoring system rated for that loaded weight is mandatory. A cone bottom tank cannot stand on its own; it requires a matching cone bottom stand sized to the 60-inch diameter. Here is the practical read on that 1.9 rating: every chemical on the compatibility list below, including 98% sulfuric acid and 50% ferric chloride, falls under that density ceiling, so the tank's SG rating is not the limiting factor for any chemical it can hold. Before you order steel, walk through our Cone Bottom Tank Stand Compatibility Matrix for Norwesco, Snyder, and Enduraplas, and confirm your volume against the Tank Sizing Calculator and Tank Sizing Guide. See the technical drawing on this page for the dimensioned cone geometry and fitting locations, and because eyeballing level through the wall is unreliable at 103 inches of height, plan a gauge using our Tank Level Gauge Selection guide.
Chemical compatibility
This is a polyethylene tank with a 1.9 SG rating. Our resin classification for this model is recorded as HDLPE pending final confirmation, so before chemical service confirm HDLPE versus XLPE with us at 866-418-1777, because cross-linked and linear polyethylene resist different chemistries. Fittings and gaskets must be selected per chemical, not per tank, and always verified against the OEM chemical-resistance chart for your exact concentration and operating temperature. None of the chemicals below requires a vessel rated above this 1.9 SG tank.
Chemicals this tank can hold (with the fitting and gasket materials they call for) include Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS fittings, EPDM gaskets), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC fittings, Viton gaskets), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC fittings, Viton gaskets), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Cross-reference any of these in our full Chemical Compatibility Database before you specify hardware.
The mistake to avoid
The single most expensive error on a cone bottom chemical tank is mismatching the gasket to the chemical. Sodium hypochlorite, hydrochloric, hydrofluoric, phosphoric, sulfuric, and hydrogen peroxide all call for Viton (or CPVC and Aflas), not the EPDM that suits the salts and glycols. Putting an EPDM gasket on a Viton-service chemical, or running aggressive acids through PVC where 316SS or CPVC is specified, leads to failure at the fitting first. Confirm your concentration and temperature against the OEM chart, and do not assume one tank covers your whole chemical list at a single hardware spec.
