The Enduraplas 2000 Gallon Black Cone Bottom Tank is built for full-drain bulk chemical service where you cannot afford settled solids or a heel left in the bottom. The cone-bottom geometry empties to the center outlet by gravity, and the 1.9 specific-gravity rating means this tank is engineered to carry dense chemistry, not just water. At 2,000 gallons in a 90-inch diameter footprint standing 113 inches tall, it is a tall, narrow vessel that needs a matched cone-bottom stand to support its load safely.
Will this tank work for your chemical?
This is a black polyethylene cone bottom tank rated to a 1.9 specific gravity. Full of water it holds roughly 16,680 lb, and at its maximum rated contents weight it is engineered to carry about 31,692 lb of product. That ceiling matters: at 2,000 gallons, a 1.9 SG rating means you can run this tank full of a chemical up to 1.9 times the density of water, not a derated partial fill. Buyers of dense chemistry like 98% sulfuric acid or ferric chloride can fill the full volume rather than backing off to protect the walls. A cone bottom tank like this never sits flat on the ground, so size your stand and slab to the full loaded weight, not the empty shell. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the loaded math against your pad, and review the Cone Bottom Tank Stand Compatibility Matrix before you order a stand.
Chemical compatibility
This tank is polyethylene rated to a 1.9 specific gravity. The exact resin grade is not confirmed in our data, so confirm HDLPE versus XLPE construction with us at 866-418-1777 before committing this tank to chemical service. Compatibility below is concentration- and temperature-specific, so match your exact conditions before ordering. Fitting and gasket materials are called out per chemical because the tank wall is only half the system.
Confirmed compatible chemicals on this SG-1.9 tank include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (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 (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Note the gasket split: chlorinated and oxidizing chemistries such as hydrochloric acid, sodium hypochlorite, phosphoric acid, and hydrogen peroxide call for Viton rather than EPDM, and peracetic acid specifies Aflas. Always cross-check your exact concentration and temperature in our Chemical Compatibility Database.
Avoid the costly mistake on this tank
The fitting and gasket material is where most chemical installs go wrong. Matching the tank resin and SG but bolting on the wrong gasket is the common failure that turns a good tank into a leak. Sodium hypochlorite, hydrochloric acid, and the other oxidizers above will degrade EPDM and need Viton; DEF and peracetic acid need 316SS hardware, not standard PVC. The cone outlet size also drives your drain and valve selection, so confirm the outlet and fitting sizes with us at 866-418-1777 before you spec the bottom valve. Plan your top penetrations before you cut a single hole so vent, fill, level, and drain do not conflict, and label the vessel correctly for the chemical it holds. See our fitting placement strategy guide, the level gauge selection guide, and the label and signage compliance guide. Refer to the technical drawing on this page for dimensional detail.
This Enduraplas cone bottom tank ships LTL freight from the nearest plant in our network, Converse, TX or Neche, ND, quoted live to your ZIP. Southwest and Texas buyers draw the shorter lane from Converse, TX, while northern buyers ship from Neche, ND. This is a heavy LTL load once filled, so run the numbers with the loaded weight in mind: get a freight estimate with the Freight Cost Estimator or call 866-418-1777 to lock in your fittings, stand, and freight in one order.
