The Snyder Industries 3000 Gallon 30 Degree Cone Bottom Tank is a white polyethylene cone bottom tank built for process and chemical-handling work where you need to drain completely between batches. It holds 3000 gallons, stands 120 inches tall, and sits on a 95 x 95 inch footprint, so plan your support stand and overhead clearance around those numbers before you order. The 1.5 specific gravity rating means it is engineered for liquids heavier than water, and the 30-degree cone bottom is steep enough to clear settling coagulant solids toward the outlet between batches instead of letting them cake on a flat floor.
Will this cone bottom tank work for your application?
This is a Snyder cone tank that requires a steel or fiberglass stand, because the entire load bears through the cone and outlet rather than a flat base. Size that stand and its foundation to the heaviest liquid you will store, not to water. Filled with water this tank carries 25,020 pounds; at the full 1.5 specific gravity rating it holds up to 37,530 pounds of contents on a 95 x 95 inch footprint, 120 inches tall. Build the structure to the 37,530-pound figure so it is rated for the densest product you plan to run. The tank comes configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for filling, inspection, and cleanout. See the technical drawing on this page for exact fitting locations and cone dimensions, then run your throughput through the Tank Sizing Calculator and Tank Sizing Guide to confirm 3000 gallons is the right cone tank for the job.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. The resin reads as HDLPE but is not fully confirmed, so confirm HDLPE versus XLPE with us before you put it into chemical service, since the resin difference drives long-term chemical resistance. At the 1.5 rating, this tank is suited to these chemicals when paired with the right fittings and gaskets: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets); Aluminum Sulfate at 50% (PVC, EPDM); Calcium Chloride at 40% (PVC, EPDM); DEF at 32.5% (316SS fittings, EPDM gaskets); Ferrous Sulfate at 20% (PVC, EPDM); Magnesium Chloride at 30% (PVC, EPDM); Sodium Carbonate at 30% (PVC, EPDM); Urea Solution at 50% (PP/PVC, EPDM); and Ozonated Water up to 10 PPM (PVC, EPDM). One important build note: every in-spec chemical here runs PVC or PP fittings except DEF, which calls for 316 stainless steel fittings with EPDM gaskets. If you are storing DEF, order the stainless build, not the standard PVC fittings. Compatibility is concentration- and temperature-specific, so verify your exact service conditions against the OEM chemical-resistance chart and our Chemical Compatibility Database before committing.
Chemicals that need a higher-SG tank
Some chemicals are compatible with polyethylene but exceed this tank's 1.5 specific gravity rating and require a 1.9-rated tank instead. If your product is on this list, step up to the heavier-rated version rather than forcing this 1.5 unit to do the job: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Gasket choice splits on this list too: most run EPDM, but Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Phosphoric Acid, Sodium Hypochlorite, and Sulfuric Acid call for Viton, and Peracetic Acid needs Aflas. Check the full Chemical Compatibility Database for the exact fitting and elastomer build before you order.
