The Snyder Industries 10500 Gallon Vertical Chemical Storage Tank (SII-5330100N39) is built from high-density linear polyethylene with a 1.4 specific gravity rating, sized for bulk chemical storage where you need real volume in a single footprint. It stands 169 inches tall on a 142 x 142 inch footprint and holds 10,500 gallons. Full of water that is 87,570 pounds; at its maximum rated contents weight the tank carries up to 122,598 pounds, so the pad and ring-wall foundation under it have to be engineered for that load before anything gets filled. This is a vertical storage tank for operators running DEF, urea solution, and similar chemistries that stay within a 1.4 SG envelope.
Will it work for your application?
Match the contents to the 1.4 SG rating, not just to the gallon number. The 1.4 rating means this tank is built for liquids up to a 1.4 specific gravity at full capacity. The full-water weight of 87,570 pounds reflects water at 1.0 SG; a heavier chemical at this fill level pushes toward the 122,598-pound maximum rated contents figure, which is why the rating ceiling matters as much as the volume. This tank is not pre-fitted for a specific chemistry, so specify fitting and gasket material per your service: 316SS fittings with EPDM gaskets for DEF, PP/PVC fittings with EPDM gaskets for urea solution. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the fill level your chemistry allows, and plan fittings, manways, and outlets around your fill-and-draw cycle. Refer to the technical drawing on this page for fitting locations and dimensional detail before you set the foundation.
Chemical compatibility
This is an HDLPE tank rated to 1.4 specific gravity. At that rating it suits DEF at 32.5% (316SS fittings, EPDM gaskets) and urea solution at 50% (PP/PVC fittings, EPDM gaskets). Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and confirm fitting and gasket material for your exact service. Many common chemistries are compatible with the polyethylene but require a higher-SG tank than this 1.4 unit. The 1.5-SG group includes acetic acid, aluminum sulfate, calcium chloride, ferrous sulfate, magnesium chloride, sodium carbonate, and ozonated water. The 1.9-SG group covers heavier-duty service such as 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 material shifts with chemistry: DEF and urea run EPDM, but aggressive oxidizers including sodium hypochlorite, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, phosphoric acid, and sulfuric acid call for Viton, and peracetic acid calls for Aflas. Sulfuric acid is the outlier on fittings, requiring CPVC rather than the PVC or PP used elsewhere. If your chemistry is on a higher-SG list, step up to a 1.5 or 1.9 SG tank rather than running it here. Cross-reference everything against our Chemical Compatibility Database.
The mistake to avoid
The expensive error on a tank this size is treating the SG rating as advice instead of a limit. This unit is rated 1.4 SG; sodium hypochlorite, sulfuric acid, ferric chloride, and the other 1.9-SG chemistries listed above will overstress the wall over time if stored here at full capacity. Pick the SG rating for the heaviest liquid you will actually store, specify fitting and gasket materials per the OEM chart, and engineer the foundation for the full 122,598-pound loaded weight. For instrumentation, our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options; for spill control review the Snyder Captor Plus 110% containment comparison, and for compliance see our resources on tank labeling and signage and chemical sampling protocol.
