The Snyder Industries 2500 Gallon Heavy Duty Cone Bottom Tank (SKU 8350000N51) is a 1.9 specific-gravity black cone tank molded from High Density Linear Polyethylene for full-drain chemical and process service. The conical floor empties completely on every cycle, so you are not leaving sludge, settled solids, or unmixed concentrate behind. This is the heavy-duty wall build, rated to 1.9 specific gravity, which is what lets it hold dense acids and concentrated treatment chemicals that would over-stress a 1.5-rated water tank. At 1.9 SG this is the top dense-chemical rating in this family; nothing heavier is needed or available, so you are not under-buying by starting here.
Will it work for your application?
The tank holds 2500 gallons and stands 104 inches tall on a 95 x 95 inch footprint, so plan your stand height, mixer clearance, and ceiling before ordering. Empty water fill weighs 20,850 lb; loaded to the full 1.9 SG rating the contents can reach 39,615 lb, so the supporting stand and pad must be engineered for that load, not for water weight. Because this is a cone-bottom tank, it requires a matching stand or structural support ring to elevate the discharge cone. Factory fitting configuration (port count, size, and location) is confirmed per order, so see the technical drawing on this page for the discharge port location and verify your plumbing drop before you build. For sizing across the family, the Tank Sizing Calculator and Tank Sizing Guide help you check capacity and footprint, and our 2500 gallon 15 degree cone bottom buyer's guide, 2500 gallon 30 degree cone bottom with poly stand guide, and cone bottom tank stand compatibility matrix cover stand pairing.
Chemical compatibility
This is an HDLPE shell rated to 1.9 specific gravity, which clears the full dense-chemical band. The chemicals below are drawn from the OEM chemical-resistance chart and are concentration- and temperature-specific, so verify your exact service conditions against that chart before committing. The listed concentrations and the fitting and gasket materials that pair with each are: 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, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (concentration not specified on the OEM chart, confirm your exact strength; PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (concentration not specified, confirm strength; PP/316SS, EPDM), Sodium Bisulfate (concentration not specified, confirm strength; PVC/PP, EPDM), Sodium Bisulfite (concentration not specified, confirm strength; PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (concentration not specified, confirm strength; PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM; no dedicated page yet, see the main database below). Match the fitting and gasket material to the chemical, not just the tank, and browse the full Chemical Compatibility Database for any service not listed.
The mistake to avoid
The most common error on a dense-chemical install is plumbing the fittings in the wrong elastomer. Match the gasket to the chemical:
- Viton gaskets: hydrochloric, hydrofluoric, sulfuric, phosphoric acids plus the oxidizers hydrogen peroxide and sodium hypochlorite.
- Aflas gaskets: peracetic acid.
- EPDM gaskets: every other listed chemical (the salts, carbonates, glycols, and urea).
Fitting material matters too: 98% sulfuric needs CPVC, and DEF, peracetic acid, propylene glycol, and zinc orthophosphate call for 316SS in the pairings above. Installing an EPDM gasket on a Viton-required acid will fail the seal even though the polyethylene shell is fine. The second mistake is sizing the stand for water weight: this tank can carry up to 39,615 lb fully loaded, far above its 20,850 lb water fill, so size the structure for the rated contents weight. For secondary containment planning on Snyder chemical tanks, the Snyder Captor Plus 110% containment vs UL-142 comparison walks through the SPCC tradeoffs.
