The Enduraplas 870 Gallon White Cone Bottom Tank with Stand (SKU THC00870KW) is a full-cone vessel built for batching, dosing, and settling where you need contents to drain toward the outlet rather than pool on a flat floor. It stands 95 inches tall on a 60-inch tank diameter and holds 870 gallons, with the cone carried on an integrated stand so the 3" PP female NPT bulkhead outlet clears the floor for gravity feed or pump suction. The tank is molded from natural white polyethylene, weighs roughly 200 lb empty, and carries a 1.9 specific gravity rating with FDA-approved resin.
Will it work for your process
On a cone bottom tank the specific gravity rating is the number that governs the buy. Filled with water the contents weigh about 7,256 lb; at the full 1.9 SG rating the tank is engineered to carry up to 13,786 lb of contents. Match your fluid's density against that rating before you order - if your product is heavier than water, run the numbers through the Tank Sizing Calculator and Tank Sizing Guide to confirm you have headroom. Fluid enters and vents through the 16" threaded vented manway on top and drains through the 3" PP bulkhead at the cone tip. Note that the 60" figure is the tank outer diameter, not the stand base - there is no stand footprint dimension in our data, so confirm the stand base width with us for pad or curb fit. Buyers search this as an 870 gallon cone bottom tank with stand.
Chemical compatibility
This tank is molded from a high-density polyethylene (resin type HDLPE versus XLPE is unconfirmed in our data - confirm with us before committing to chemical service, since the two carry different ratings) and rated to 1.9 specific gravity. The pairings below come from the Snyder Industries OEM chemical resistance chart and are concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and fitting and gasket materials before ordering. At the tank's 1.9 SG rating it can hold, among others: Hydrochloric Acid (37%, PVC fittings, Viton gaskets), Sulfuric Acid (98%, CPVC, Viton), Sodium Hypochlorite (<16.5%, PVC, Viton), Ferric Chloride (50%, PVC, EPDM), Phosphoric Acid (85%, PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Ethylene Glycol (100%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), and Hydrofluoric Acid (48%, PP/PVC, Viton). Lower-density fluids like DEF (32.5%, 316SS, EPDM) and Urea Solution (50%, PP/PVC, EPDM) map to a 1.35 SG requirement and sit well within this tank. Ozonated water (up to 10 PPM, PVC, EPDM) is also on the chart. See the full Chemical Compatibility Database for every listing, and note that gasket material changes by chemical - EPDM, Viton, and Aflas are not interchangeable.
The mistake to avoid
Do not spec the outlet fitting from the tank alone. The stock 3" bulkhead is polypropylene, but the wetted fitting and gasket you install must match your chemical - Viton for oxidizers like hypochlorite and peroxide, EPDM for glycols and DEF, Aflas for peracetic acid. A PP-only outlet on an aggressive oxidizer will fail long before the tank does. That 3" bulkhead is also the only outlet in our data - no side fill, level, or lower-drain ports are listed - so if your skid needs a fill line or level port, ask before you order rather than assuming multi-port. And because the cone angle is not specified in our data, confirm the drain slope and clearance under the outlet with us before building a pump skid around it.

Review the technical drawing on this page for outlet and manway placement, and confirm resin, SG, and fitting materials together - not one at a time - before you commit to chemical service.
