2000 Gallon 30 Degree HDPE Cone Bottom Tank in White

The Snyder Industries 2000 Gallon 30 Degree Cone Bottom Tank (SKU SII-5070000N45) is a White polyethylene cone bottom tank rated for a specific gravity of 1.9, which puts it among the heaviest-duty cone tanks built for chemical service. The 30-degree cone forces near-complete gravity drainage, so process chemicals, coagulants, and dosing solutions empty cleanly without leaving a residual heel. Standing 101.75 inches tall on a 90 x 90 inch footprint, this cone tank needs a properly engineered steel or poly stand to carry the cone and the load above it.

Will it work for your application?

This is a true chemical-rated cone bottom tank: the 1.9 SG rating means the polyethylene wall is molded to hold dense liquids well beyond the weight of water. Full of water the contents weigh 16,680 lb, and the tank is rated to carry up to 31,692 lb of contents at its maximum specific gravity, so you keep real margin for heavier solutions. The technical drawing on this page shows the molded fitting layout, which includes a flange outlet at the cone tip for gravity drain or recirculation, an 18-inch PE threaded and vented connection, and a manway with 15-inch access for inspection, fill, and venting. Confirm your drain plumbing lands on the flange, and that your dosing pump, level sensor, and vent line all match the connections shown before you finalize the install. The Tank Sizing Calculator and Tank Sizing Guide help you confirm the 2000-gallon working volume fits your batch and turnover.

Chemical compatibility

This tank is molded from high-density polyethylene and carries a 1.9 specific gravity rating. Before any chemical service, confirm the exact resin of your unit, because resin formulation changes which chemicals are appropriate. Always verify against the OEM chemical-resistance chart at the exact concentration and temperature you intend to run; the values below pair each chemical with the recommended fitting and gasket materials.

Chemicals this tank handles at its 1.9 SG rating include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), ethylene glycol (100%, PVC, EPDM), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), ferrous sulfate (20%, PVC, EPDM), hydrochloric acid (37%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), magnesium chloride (30%, PVC, EPDM), peracetic acid (30%, 316SS, Aflas), phosphoric acid (85%, PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate (30%, PVC, EPDM), sodium hypochlorite (under 16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM; covered in the database generally). At 1.9 SG this is the heaviest-rated cone option we carry, so there is no higher-SG step-up for this configuration. Match the fitting and gasket materials to the chemical you run, not just the tank wall. Full details live in our Chemical Compatibility Database.

The mistake to avoid

The most common error on a high-SG cone tank like this is matching only the polyethylene wall to the chemical and ignoring the fittings and gaskets. Sodium hypochlorite, sulfuric acid, peracetic acid, and the peroxides above all call for Viton or Aflas seals and specific fitting materials, and the wrong elastomer fails long before the tank does. Remember the manway lid gasket on that 15-inch access is itself an elastomer that must be specified in the chemical-correct material, not just the inline fitting seals. The second mistake is mounting a 1.9 SG tank without confirming the stand and anchoring are rated for the full 31,692 lb maximum contents weight plus the elevated cone load, not the 16,680 lb water figure. If you are still sizing, our cone bottom tank buyer's guide on cone-angle selection walks through the 15 vs 30 vs 45 degree tradeoff.
