The Snyder Industries 325 Gallon 30 Degree Cone Bottom Tank (SII-1560500N45) is a closed-top HDPE cone tank molded in white and delivered on a matched poly stand. The full 30-degree cone lets thick slurries, settled solids, and batched chemicals drain completely, which is why buyers running dosing, mixing, and settle-and-decant processes reach for this 325 gallon tank. It stands 55 inches tall on a 48-inch diameter footprint, carries an 18-inch lid up top for filling, mixing, and inspection, and holds a 1.9 specific gravity rating for heavier-than-water contents.
Will it work for your job?
Empty, this Snyder Industries tank weighs 145 pounds. Filled with plain water it carries about 2,710 pounds, and its maximum rated contents weight is 5,150 pounds — that ceiling is what the 1.9 SG rating buys you, so a heavy dosing chemical fills the tank's weight budget before it fills the tank's volume. On the compatible list below, only ferric- and sulfuric-class loads near 1.9 SG approach that weight ceiling; lighter loads like DEF, glycols, and urea are volume-limited, not weight-limited, so you can fill them to the brim. The tank is rated to a maximum 120 F / 48 C and carries Snyder specifications 2285 and 2282. It ships with the 18-inch closed-top lid; the cone outlet fitting and bulkhead are sized and specified separately, so match fitting material to your chemical (see the table) and plan your outlet plumbing and stand clearance before it arrives. Confirm your batch size and duty cycle with the Tank Sizing Calculator and Tank Sizing Guide.
Chemical compatibility
This HDPE cone bottom tank is molded in HDLPE (high density linear polyethylene) with a 1.9 SG rating. Per the Snyder Industries OEM chemical resistance chart — which is concentration- and temperature-specific — confirm your exact chemical, concentration, temperature, and fitting plus gasket materials before service. Because the tank is rated to 1.9 SG, no step-up tank is required for any chemical on this list, including the 1.9-demanding acids. Match the fitting and gasket to the chemical, not to habit — the wrong gasket is the most common mistake on a chemical tank:
| Chemical (conc.) | Fitting | Gasket |
|---|---|---|
| Hydrochloric Acid (37%) | PVC | Viton |
| Sulfuric Acid (98%) | CPVC | Viton |
| Phosphoric Acid (85%) | PVC | Viton |
| Sodium Hypochlorite (<16.5%) | PVC | Viton |
| Hydrogen Peroxide (50%) | PVC | Viton |
| Ferric Chloride (50%) | PVC | EPDM |
| Ethylene Glycol (100%) | PVC | EPDM |
| Peracetic Acid (30%) | 316SS | Aflas |
| Potassium Hydroxide (saturated) | PVC | EPDM |
| DEF (32.5%) & Urea Solution (50%) | 316SS / PP-PVC | EPDM |
Other compatible loads include Acetic Acid, Hydrofluoric Acid, Sodium Thiosulfate, and Potassium Carbonate — verify each in the full Chemical Compatibility Database before you order.
