The Enduraplas 2500 Gallon White Cone Bottom Tank is a full-drain process vessel built for chemical handling, with a 1.9 specific gravity rating that puts it well above the typical 1.5 SG cone tank. That rating is the whole point of this tank: at 2,500 gallons it can hold up to 39,615 lb of rated contents, so it carries dense liquids that would over-stress a lighter-rated tank. The cone bottom drains completely to the center outlet, which is why processors choose this geometry for batching, mixing, DEF and glycol blending, and clean-out between chemistries.
Will it work for your application
This is a natural white polyethylene cone bottom tank standing 120 in tall on a 90 x 90 in footprint. Plan your stand and headroom around those numbers - a cone tank holds its weight up on legs, so the 120 in height is to the top of the tank, not counting the stand you mount it on. Full of water it weighs about 20,850 lb; at its 1.9 SG rating the contents alone reach 39,615 lb, so the supporting stand and pad must be engineered for the actual liquid you plan to store. The 1.9 SG rating and full-drain cone make this a strong fit for storing or blending dense fluids - DEF, ethylene glycol, urea solution, and brines all sit comfortably within its design. Fitting sizes and outlet configuration for this tank are not listed on this page, so confirm bulkhead and outlet size with us before ordering valves. Before you order, match the tank to a stand using our cone bottom tank stand compatibility matrix for Norwesco, Snyder, and Enduraplas, and if you are weighing the 15-degree versus 30-degree cone or a poly stand, the 2500 gallon 15 degree cone bottom tank buyer's guide and the 2500 gallon 30 degree cone bottom tank with poly stand guide walk through the trade-offs. For full dimensional detail, see the technical drawing on this page.
Chemical compatibility
This tank is molded from polyethylene (the resin is recorded as HDLPE but ends with a question mark in our data - confirm HDLPE versus XLPE with us before committing it to chemical service) and carries a 1.9 SG rating, so it accommodates heavy process chemicals at the concentrations below. Always cross-check against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and spec your fittings and gaskets to the chemical, not just the tank. Compatible chemistries from our database include sulfuric acid at 98% (CPVC fittings, Viton gaskets), hydrochloric acid at 37% (PVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), phosphoric acid at 85% (PVC, Viton), hydrofluosilicic acid at 26% (PP/PVC, Viton), acetic acid at 60% (PP/PVC, EPDM), peracetic acid at 30% - the one chemistry here that demands 316SS fittings with Aflas gaskets, not the usual plastic-and-EPDM kit - hydrogen peroxide at 50% (PVC, Viton), sodium hypochlorite at under 16.5% (PVC, Viton), ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, aluminum sulfate at 50%, calcium chloride at 40%, magnesium chloride at 30%, sodium carbonate at 30%, potassium carbonate at 50%, potassium hydroxide (saturated), sodium thiosulfate at 40%, sodium bisulfate (concentration not specified in our data; confirm your strength against the OEM chart), sodium bisulfite (concentration not specified), polyaluminum chloride (concentration not specified), zinc orthophosphate (PP/316SS, EPDM; concentration not specified), ethylene glycol at 100%, propylene glycol (concentration not specified), urea solution at 50%, DEF at 32.5% (316SS, EPDM), and ozonated water up to 10 PPM. Most of these call for PVC fittings with EPDM gaskets; the oxidizers and strong acids step up to Viton, while DEF and peracetic acid require 316SS rather than plastic - so read each chemical's page before you order valves and bulkhead fittings. Full details live in our chemical compatibility database.
The mistake to avoid
The most common error on a cone bottom of this size is buying for water density and then storing something heavier. The 20,850 lb full-water figure is not the design load if you are running acid, brine, or another dense chemistry - the 1.9 SG rating exists precisely so the tank itself survives heavy liquids, but your stand, anchors, and pad have to carry the real 39,615 lb. Confirm the resin (HDLPE vs XLPE) for your specific chemical, and never assume an EPDM gasket suits an oxidizer; sodium hypochlorite, hydrogen peroxide, and the strong acids above all want Viton, and peracetic acid wants Aflas on 316SS. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
This 2500 gallon cone bottom tank ships LTL freight from the nearest of our two Enduraplas plants - Converse, TX or Neche, ND - quoted live to your ZIP. Two origins shorten the lane: buyers across the South and Southwest pull from Texas, while the Upper Midwest and Plains pull from North Dakota, which trims LTL distance versus a single-plant supplier. Get your number with the Freight Cost Estimator or call us at 866-418-1777, and we will help you match the tank, stand, and fittings to your chemistry.
