The Snyder Industries 3000 Gallon Cone Bottom Tank with Poly Stand (part 40553, SKU SII-8360037) is a closed-top, 30-degree full-drain vessel molded in white High Density Linear Polyethylene and paired with a matching polyethylene stand so the cone gravity-empties into a pump, hose, or transfer line without leaving a heel behind. It stands 135 inches tall on a 95-inch diameter footprint, weighs 940 pounds empty, and carries an 18-inch lid for fill and inspection access. Snyder rates the resin to a 1.9 specific gravity and a maximum contents temperature of 120 F (48 C), which is what makes this a true chemical-service tank rather than a plain water vessel.
Will it hold your product
The 30-degree cone drains completely, so this Snyder cone bottom tank suits batching, mixing, and dosing where you cannot afford to leave product in the bottom. Sizing is where cone tanks catch people out: 3000 gallons of water alone weighs 25,020 pounds, and at the tank's full 1.9 SG rating the contents can reach 47,538 pounds. That entire load rides on the poly stand and your slab, so confirm both are engineered for the filled weight before you order. Run your target chemical through our Tank Sizing Calculator and the Tank Sizing Guide, and if you are still weighing a poly frame against steel, the stand selection decision tree and Snyder stand compatibility matrix lay out the tradeoffs.
Chemical compatibility
This tank is molded in HDLPE at a 1.9 specific gravity rating, which is Snyder's top density class. Every chemical on Snyder's approved list for this vessel calls for a required SG of 1.9 or lower, so none is ruled out on density grounds. Per the Snyder Industries OEM chemical resistance chart, the 1.9-SG heavy chemicals include Hydrochloric Acid at 37% (details, PVC fittings, Viton gaskets), Sulfuric Acid at 98% (details, CPVC fittings, Viton gaskets), Phosphoric Acid at 85% (details, PVC, Viton), Hydrogen Peroxide at 50% (details, PVC, Viton), Sodium Hypochlorite below 16.5% (details, PVC, Viton), Ferric Chloride at 50% (details, PVC, EPDM), and Ethylene Glycol at 100% (details, PVC, EPDM). A number of chemicals are rated only with metal or polypropylene fittings, not PVC: DEF at 32.5% (details) and Urea Solution at 50% (details) need 316 stainless or PP with EPDM, Peracetic Acid at 30% (details) requires 316SS with an Aflas gasket, and Propylene Glycol (details) and Zinc Orthophosphate (details) call for PP or 316SS. The chart is concentration- and temperature-specific, so match your exact chemical, concentration, temperature, and the listed fitting and gasket material before committing. The full Chemical Compatibility Database carries the rest of the approved list, and the top-fitting placement guide covers vent, fill, and drain layout for closed-top service.
The mistake to avoid
The costly error on a 3000 gallon cone tank is specifying it for a chemical that outruns either the resin or the stand, or assuming one gasket and fitting spec transfers to the next chemical. It does not: Viton is called for on the strong acids and hypochlorite, EPDM covers the glycols, sulfates, and carbonates, and Peracetic Acid needs Aflas with 316 stainless. Likewise, PVC does not cover everything, DEF, urea, peracetic, propylene glycol, and zinc orthophosphate all need 316SS or PP. Confirm your chemical sits within the 1.9 SG rating and the 120 F ceiling, then verify the exact fitting and gasket family for it. See the technical drawing on this page for the cone geometry and 18-inch lid location before you plumb it.
