The Enduraplas 2520 Gallon Green Cone Bottom Tank with Stand (SKU THC02520KG) is a full-drain polyethylene vessel built for batch processing, mixing, and chemical dosing where you need to empty completely between runs. It holds 2,520 gallons, stands 108" tall on a 110"-diameter footprint, and ships from the factory with the stand that supports the cone. Empty tank weight is 500 lb, and the tank body carries a 1.9 specific gravity rating - the number that decides whether it can safely hold what you plan to put in it.
Will it work for your job
Filled with water this tank carries roughly 21,017 lb; at its full 1.9 SG rating the maximum rated contents weight is 39,932 lb. That spread matters: the 1.9 rating means the wall is engineered for dense liquids up to 1.9 times the weight of water, so heavier chemical solutions stay within design load. Plumbing comes ready with a 3" PP Female NPT Bulkhead Fitting at the cone outlet for gravity discharge and a 16" Threaded Vented Manway up top for filling, mixing access, and venting. The tank is FDA Approved polyethylene and green in color. Run your target liquid through the Tank Sizing Calculator and the Tank Sizing Guide to confirm your loaded weight before you order, and check the technical drawing on this page for exact port placement. Note that 1.9 is the top SG rating offered on this tank, so there is no denser-rated version to step up to - the decision here is confirming resin against your chemistry, not chasing a bigger SG number.
Chemical compatibility
This tank is molded polyethylene with a 1.9 SG rating; the resin is recorded as HDLPE but flagged for confirmation - confirm HDLPE vs XLPE with us before committing to chemical service, since crosslinked and high-density polyethylene resist different chemistries. That call is load-bearing, not paperwork: several of the aggressive acids listed below - hydrochloric at 37%, sulfuric at 98%, phosphoric at 85% - are precisely the chemistries where XLPE and HDLPE resistance diverge, and those are exactly the fluids a cone-bottom chem tank gets bought for. Compatibility below is drawn from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and fitting plus gasket materials before filling.
Chemicals the OEM chart supports for a 1.9 SG tank like this one include Ethylene Glycol (100%, PVC fittings, EPDM gaskets), Ferric Chloride (50%, PVC/EPDM), Ferric Sulfate (60%, PVC/EPDM), Hydrochloric Acid (37%, PVC fittings with Viton gaskets), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Peracetic Acid (30%, 316SS fittings, Aflas gaskets), 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 and Sodium Bisulfite (PVC/PP, EPDM), Sodium Hypochlorite (under 16.5%, PVC with Viton), Sodium Thiosulfate (40%, PVC/EPDM), Sulfuric Acid (98%, CPVC fittings with Viton gaskets), and Zinc Orthophosphate (PP/316SS, EPDM). Lower-SG-rated chemicals sit well within this tank's 1.9 rating too, but watch their fitting callouts: DEF (32.5%) requires 316SS fittings with EPDM gaskets - not PVC - and Urea Solution (50%) calls for PP/PVC with EPDM. Rounding out the lower-SG group are Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), Ferrous Sulfate (20%), Magnesium Chloride (30%), and Sodium Carbonate (30%), each on PVC/EPDM. Ozonated Water (up to 10 PPM) also appears on the chart - call to confirm that one against your exact setup. Matching the wrong elastomer (EPDM where Viton is required, or vice versa) is the most common and costly mistake on a cone-bottom chemical tank, so read the fitting and gasket columns as closely as the chemical name. See the full Chemical Compatibility Database for concentration and temperature detail.
The mistake to avoid
Do not order the tank until the resin is confirmed. Because this SKU's resin carries a "confirm HDLPE vs XLPE" flag, the single most important step before chemical service is calling us to lock the exact resin against your chemistry - the SG rating alone does not settle it. Pair that with the correct fitting and gasket materials from the chart above, and match the stand to the loaded weight; our stand selection decision tree and the Norwesco, Snyder, and Enduraplas stand compatibility matrix walk through it.
