The Enduraplas 2520 Gallon Black Cone Bottom Tank with Stand (SKU THC02520KB) is a full-drain polyethylene tank built for chemical storage and batch dispensing where you need the vessel to empty completely. The tank body stands on its stand at 108 inches tall over a 110-inch diameter footprint, carries a 3-inch PP female NPT bulkhead outlet at the cone tip, and a 16-inch threaded vented manway up top for filling, mixing access, and free venting. It's rated to a 1.9 specific gravity, which is what makes it a genuine chemical tank rather than a water-only vessel.
Will it hold your product
Empty, the tank and stand weigh about 500 lb. Filled with water it carries roughly 21,017 lb, and at its full 1.9 SG rating the contents alone can reach about 39,932 lb — so your stand pad, anchoring, and floor loading have to be sized for the heaviest product you'll ever run, not for water. The black polyethylene wall resists UV and hides algae growth for outdoor cone-bottom service. Confirm your steel or poly stand rating against that loaded number before you fill; our stand selection decision tree and the Norwesco/Snyder/Enduraplas stand compatibility matrix walk through the trade-offs. Use the Tank Sizing Calculator and Tank Sizing Guide to match the 2520-gallon capacity to your batch volume and refill cadence.
Chemical compatibility
This is a polyethylene tank with a 1.9 SG rating. The resin is listed as HDLPE but flagged for confirmation, so verify HDLPE versus XLPE with us before you commit to chemical service — the resin choice changes what you can safely store, and the table below stays provisional until it's settled. Compatibility is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and both fitting and gasket materials before ordering. At its 1.9 SG the tank is rated for concentrated chemicals including sulfuric acid (98%, CPVC fittings, Viton gaskets), hydrochloric acid (37%, PVC/Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), phosphoric acid (85%, PVC/Viton), hydrogen peroxide (50%, PVC/Viton), sodium hypochlorite (up to 16.5%, PVC/Viton), ferric chloride (50%, PVC/EPDM), ferric sulfate (60%, PVC/EPDM), potassium carbonate (50%, PVC/EPDM), potassium hydroxide (saturated, PVC/EPDM), sodium thiosulfate (40%, PVC/EPDM), ethylene glycol (100%, PVC/EPDM), peracetic acid (30%, 316SS/Aflas), sodium bisulfate, sodium bisulfite (both PVC/PP, EPDM), propylene glycol, zinc orthophosphate (both PP/316SS, EPDM), and polyaluminum chloride (PVC/EPDM). Lower-SG chemicals it also handles include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), urea solution (50%), sodium carbonate (30%), magnesium chloride (30%), and ferrous sulfate (20%). Ozonated water up to 10 PPM is also on the chart (PVC fittings, EPDM gasket). Note the included 3-inch PP bulkhead is a starting point, not universal: DEF and urea require a 316SS fitting with an EPDM gasket, and peracetic acid a 316SS fitting with Aflas — so plan on swapping the stock outlet for those services. Check the full Chemical Compatibility Database for the specific pairing you plan to store.
The mistake to avoid
The costly error on a cone-bottom chem tank this size is sizing your stand and gasket to water weight. Water is only about 21,017 lb; a 1.9 SG product loads the stand to nearly 39,932 lb, and a cone-bottom tank concentrates that entire load on the stand's ring and legs rather than a flat pad. Match both the stand rating and the bulkhead gasket to your heaviest, most aggressive product — not to water — pick EPDM, Viton, or Aflas per the chart above, and confirm the resin before chemical service. See the technical drawing on this page for the manway, outlet, and cone geometry.
