The Snyder Industries 15 Gallon Heavy Duty Open Top Cone Bottom Mixing Tank is built for small-batch chemical mixing, dosing, and day-tank service where you need to see and access the contents from the top while draining completely from the cone. Molded in black High Density Linear Polyethylene with a 1.9 specific gravity rating, this open top cone bottom tank measures 17 inches in diameter and 28 inches tall, with a 17.0 x 17.0 inch footprint that fits tight equipment skids and bench setups.
Will this cone tank work for your application?
The full water weight of this tank is 125 lb, and at its 1.9 specific gravity rating the maximum rated contents weight is 238 lb - so you can run dense solutions and slurries well past the weight of plain water without overstressing the wall. The cone bottom drains to a single low point, which is what makes it a true mixing tank: no dead pocket where solids settle out or product is left behind. Because it is an open top design, you mix, sample, and clean from above. This tank ships as a bare open-top cone shell - the bottom-drain bulkhead, valve, and gaskets are selected separately to match your chemical, using the materials below. A cone bottom cannot free-stand, so you pair it with a cone bottom stand to hold the tank upright and give you clearance below the 28 inch height for the drain valve. See the technical drawing on this page for the cone geometry and dimensional layout before you size a stand or agitator.
Chemical compatibility
This tank is molded in HDLPE (High Density Linear Polyethylene) and carries a 1.9 specific gravity rating, which covers the dense acids and concentrated solutions below. Confirm whether your service needs HDLPE or XLPE resin before you commit the tank to chemical duty. Always check the chemical, its concentration, and your operating temperature against the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific - a chemical that is fine at room temperature can attack the resin or fittings when warm or more concentrated.
Verified compatible chemicals for this tank, with the fitting and gasket materials they call for, include: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Potassium Hydroxide (saturated, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Ethylene Glycol (100%, PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Other verified options include Ferrous Sulfate, Hydrofluosilicic Acid, Polyaluminum Chloride, Potassium Carbonate, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Thiosulfate, and Zinc Orthophosphate. Two services here need stainless, not plastic: DEF and Peracetic Acid both spec 316SS fittings, and Peracetic Acid is the only chemical on this list that calls for an Aflas gasket. Sodium Hypochlorite is capped at under 16.5% concentration and must run Viton, never EPDM. Match every fitting and gasket to the chemical, and see our Chemical Compatibility Database for full details.
The mistake to avoid
The single most common error with a cone bottom mixing tank is treating the 1.9 specific gravity rating as a license to ignore fitting and gasket selection. The polyethylene wall handles the weight - that is what the 238 lb max rated contents figure tells you - but a bottom drain valve, gasket, or sample port in the wrong material will fail long before the tank does. Spec PVC, CPVC, polypropylene, or 316 stainless fittings with the right EPDM, Viton, or Aflas gaskets per the chart above, and confirm your resin choice for the service. Our fitting placement guide and cone bottom tank stand compatibility matrix walk through both decisions.
