The Snyder Industries 2500 Gallon Double Wall Liquid Chemical Storage Tank pairs a vertical storage tank and built-in secondary containment in one unit, molded in white High Density Linear Polyethylene (HDLPE) and rated to a 1.9 specific gravity. The outer wall captures the volume of the inner tank, so a single footprint handles primary storage and spill containment without a separate dike or basin. It holds 2500 gallons, stands 122" tall on a 102" x 102" footprint, and is built for the dense, concentrated chemicals a 1.9 SG allows. If you have been searching for a double wall tank or vertical storage tank for chemical service, this is the size class built for it. At a 1.9 specific gravity, this is the heaviest chemical-duty rating Snyder offers in this class, so there is no higher-SG step-up to chase.
Will it work for your application?
Start with weight, because the 1.9 SG rating is the reason to choose this tank. Filled with water it carries about 20,850 lb; filled to its maximum rated contents it carries up to 39,615 lb. That spread tells you the slab and forklift capacity you need before delivery, and it confirms the tank can hold a liquid up to 1.9 times the weight of water at full volume. Pour the 102" x 102" footprint as level, full-bearing concrete sized for that loaded weight. Plumbing connections come off a flange, an 18" PE threaded/vented fitting, and a manway with 15" access for entry and inspection. Your bulkhead and threaded fittings and their gaskets install at the flange and the 18" port, and the manway gasket must match the same chemical class as the rest of the plumbing. See the technical drawing on this page for exact fitting locations and elevations, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the size against your turnover and refill schedule. Because this is a containment tank for SPCC 40 CFR 112 sites, confirm the rated secondary volume meets your 110% containment requirement before ordering.
Chemical compatibility
This tank is HDLPE rated to a 1.9 specific gravity, which covers a wide range of concentrated chemicals. Match each chemical to the right fitting and gasket material, and always confirm against the OEM chemical-resistance chart at your specific concentration and temperature before committing to service. Verified-compatible chemicals for this resin and SG rating include:
- Acetic Acid at 60% (PP/PVC fittings, EPDM gasket)
- Aluminum Sulfate at 50% (PVC fittings, EPDM gasket)
- Calcium Chloride at 40% (PVC fittings, EPDM gasket)
- DEF at 32.5% (316SS fittings, EPDM gasket)
- Ethylene Glycol at 100% (PVC fittings, EPDM gasket)
- Ferric Chloride at 50% (PVC fittings, EPDM gasket)
- Ferric Sulfate at 60% (PVC fittings, EPDM gasket)
- Ferrous Sulfate at 20% (PVC fittings, EPDM gasket)
- Hydrochloric Acid at 37% (PVC fittings, Viton gasket)
- Hydrofluoric Acid at 48% (PP/PVC fittings, Viton gasket)
- Hydrofluosilicic Acid at 26% (PP/PVC fittings, Viton gasket)
- Hydrogen Peroxide at 50% (PVC fittings, Viton gasket)
- Magnesium Chloride at 30% (PVC fittings, EPDM gasket)
- Peracetic Acid at 30% (316SS fittings, Aflas gasket)
- Phosphoric Acid at 85% (PVC fittings, Viton gasket)
- Polyaluminum Chloride (PVC fittings, EPDM gasket)
- Potassium Carbonate at 50% (PVC fittings, EPDM gasket)
- Potassium Hydroxide, saturated (PVC fittings, EPDM gasket)
- Propylene Glycol (PP/316SS fittings, EPDM gasket)
- Sodium Bisulfate (PVC/PP fittings, EPDM gasket)
- Sodium Bisulfite (PVC/PP fittings, EPDM gasket)
- Sodium Carbonate at 30% (PVC fittings, EPDM gasket)
- Sodium Hypochlorite at <16.5% (PVC fittings, Viton gasket)
- Sodium Thiosulfate at 40% (PVC fittings, EPDM gasket)
- Sulfuric Acid at 98% (CPVC fittings, Viton gasket)
- Urea Solution at 50% (PP/PVC fittings, EPDM gasket)
- Zinc Orthophosphate (PP/316SS fittings, EPDM gasket)
- Ozonated Water up to 10 PPM (PVC fittings, EPDM gasket)
Full concentration- and temperature-specific data lives in our Chemical Compatibility Database. Note the fitting and gasket call-outs above: chemicals like sulfuric acid, sodium hypochlorite, and hydrogen peroxide need Viton or Aflas gaskets and the named fitting material, not standard EPDM. The most common mistake on this tank is reusing one gasket type across every connection, so spec the gasket per port to the chemical it sees.
Freight and how to order
This tank ships LTL freight from the Snyder plant in Lincoln, NE, with freight quoted live to your ZIP rather than included in the list price. Get an exact number with our Freight Cost Estimator before you buy. Because it is a double-wall containment tank built for SPCC sites, the Snyder Captor Double-Wall Tanks for SPCC 40 CFR 112 walkthrough and our 2500 Gallon Vertical Liquid Storage Tank buyer's guide are worth reading before you order.
