The Enduraplas 3200 Gallon Green Cone Bottom Tank is built for full-drain bulk chemical storage, carrying the highest density rating in the Enduraplas cone bottom line: a 1.9 specific gravity rating that lets it hold dense liquids at full strength. The cone bottom drains completely on every cycle. At 116 in tall on a 110 x 110 in footprint, this is a large-volume cone bottom tank for water treatment, agriculture, and industrial process use. It is not free-standing: a cone bottom tank is supported entirely by a matched stand, and at 1.9 SG the loaded contents reach a maximum rated weight of 50,707 lb, so the stand and foundation are mandatory capex that must be sized to the loaded weight, not the empty tank.
Will it work for your application
This is a 3,200-gallon green cone bottom tank molded from polyethylene by Enduraplas. Filled with water it carries 26,688 lb; rated for product up to 1.9 specific gravity, it is engineered for a maximum contents weight of 50,707 lb. The 110 x 110 in footprint and 116 in height set the stand and clearance you need. Because 1.9 SG is the highest-density rating offered, no heavier-duty tank is required for any chemical listed below at the listed concentrations - this tank is the ceiling. See the technical drawing on this page for fitting locations and overall dimensions, and use our Tank Sizing Calculator and Tank Sizing Guide to confirm the gallons and footprint fit your site. For stand selection, the Cone Bottom Tank Stand Compatibility Matrix walks through Enduraplas and other cone bottom stand pairings. Note that fittings and gaskets are not included - they are specified to your chemical and confirmed at order.
Chemical compatibility
This tank is polyethylene with a 1.9 specific gravity rating. The resin is recorded as HDLPE pending confirmation - confirm HDLPE versus XLPE with us before placing it in chemical service, because the resin choice changes what the tank can safely hold. That 1.9 SG rating is the headroom that makes the chemicals below workable at full strength. The values below are concentration-specific and assume ambient service; always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature. Fittings and gaskets must match the chemical, not just the tank - watch the non-default cases: DEF and Peracetic Acid require 316 stainless steel rather than plastic (Peracetic also needs an Aflas gasket), Sulfuric Acid at 98% requires CPVC rather than standard PVC, and Viton gaskets are required for Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric acids.
Compatible chemicals with the recommended fitting and gasket materials for this 1.9 SG tank include: Acetic Acid 60% (PP/PVC fittings, EPDM gaskets, details); Aluminum Sulfate 50% (PVC, EPDM, details); Calcium Chloride 40% (PVC, EPDM, details); DEF 32.5% (316SS, EPDM, details); Ethylene Glycol 100% (PVC, EPDM, details); Ferric Chloride 50% (PVC, EPDM, details); Ferric Sulfate 60% (PVC, EPDM, details); Ferrous Sulfate 20% (PVC, EPDM, details); Hydrochloric Acid 37% (PVC, Viton, details); Hydrofluoric Acid 48% (PP/PVC, Viton, details); Hydrofluosilicic Acid 26% (PP/PVC, Viton, details); Hydrogen Peroxide 50% (PVC, Viton, details); Magnesium Chloride 30% (PVC, EPDM, details); Peracetic Acid 30% (316SS, Aflas, details); Phosphoric Acid 85% (PVC, Viton, details); Polyaluminum Chloride (PVC, EPDM, details); Potassium Carbonate 50% (PVC, EPDM, details); Potassium Hydroxide saturated (PVC, EPDM, details); Propylene Glycol (PP/316SS, EPDM, details); Sodium Bisulfate (PVC/PP, EPDM, details); Sodium Bisulfite (PVC/PP, EPDM, details); Sodium Carbonate 30% (PVC, EPDM, details); Sodium Hypochlorite up to 16.5% (PVC, Viton, details); Sodium Thiosulfate 40% (PVC, EPDM, details); Sulfuric Acid 98% (CPVC, Viton, details); Urea Solution 50% (PP/PVC, EPDM, details); Zinc Orthophosphate (PP/316SS, EPDM, details); and Ozonated Water up to 10 PPM (PVC, EPDM). Cross-reference everything in our Chemical Compatibility Database before ordering.
The mistake to avoid
The costliest error on a cone bottom tank this large is reading the 1.9 SG rating as permission to skip the math. Specific gravity multiplies the load: at 1.9 SG the contents weigh up to 50,707 lb, nearly double the 26,688 lb of plain water, and the stand and foundation have to carry all of it. Match the stand to the loaded weight, and match the chemical to the right trim - a Viton gasket where the chart calls for it, 316SS or CPVC where standard PVC and EPDM will fail. For fitting layout that keeps fill, vent, drain, and level lines from interfering, see our fitting placement strategy guide, and for the right level instrument review Tank Level Gauge Selection for Chemical Service. If you store a regulated chemical, our tank labeling and signage compliance guide covers NFPA 704, GHS, and DOT placarding.
