The Snyder Industries 11500 Gallon Cone Bottom Tank (SKU 5340100N49) is a full-drain black polyethylene cone-bottom tank built for bulk chemical batching, blending, and complete-discharge service. Standing 215 inches tall on a 142.0 x 142.0 inch footprint, this is a top-end-capacity vessel rated to a 1.5 specific gravity, meaning it is engineered to hold contents up to 1.5 times the weight of water without exceeding its design limits.
Will it work for your application?
The cone-bottom geometry forces sediment and product toward a single discharge point so the tank drains clean, which is why operators choose this style for chemical metering and slurry service rather than flat-bottom storage. The molded fittings on this tank include a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, and a 12 x 13 inch fitting; reference the technical drawing on this page to confirm exact fitting locations against your piping and agitation plan before you commit. The 18-inch vented fitting is process-critical at this volume - keep it unobstructed and sized for your peak fill and draw rates, never valved closed or downsized, so the tank breathes during transfer. A cone-bottom tank of this size must be supported in a matching stand or structural cradle - it is not self-standing - so review the Cone Bottom Tank Stand Compatibility Matrix early in your layout.
Weights, sizing, and the load nobody plans for
Plan your stand and pad around the loaded weight, not the empty shell. Filled with water this tank carries roughly 95,910 lb, and at its full 1.5 SG rating the contents alone reach about 143,865 lb. That is a foundation engineering problem, not a forklift problem: a reinforced concrete pad and an engineered steel stand are mandatory at this scale. Run your fill volume through the Tank Sizing Calculator and read the Tank Sizing Guide so the stand, anchoring, and seismic or wind loads are sized to the actual contents weight. A single vessel holding this much chemical will trip SPCC and secondary-containment thresholds for most regulated chemistries, so size containment for at least 110 percent of the rated contents - the Snyder Captor Plus 110% Containment vs UL-142 / SPCC comparison walks through the difference.
Chemical compatibility
This is an HDLPE (high-density linear polyethylene) tank rated to 1.5 specific gravity. The resin designation carries a question mark in our source data, so confirm whether your tank is HDLPE or XLPE (crosslinked) before placing it in chemical service - the two resins behave differently with certain chemistries. The chemicals below are compatible with a 1.5 SG tank at the listed concentration, with the recommended fitting and gasket materials; always verify against the OEM chemical-resistance chart for your specific concentration and operating temperature.
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
For DEF and urea service, use 316 stainless wetted fittings - generic PVC or PP hardware is not appropriate for dispensing-grade DEF integrity, so do not reuse a PVC fitting kit on a DEF install. The common mistake at 1.5 SG is assuming this tank covers every chemical on your site. It does not. The chemicals below all require a higher-SG (1.9-rated) cone-bottom tank, and several call for Viton or Aflas gaskets rather than EPDM - storing them in this 1.5 SG vessel is the error that shortens tank life:
- Ethylene Glycol - PVC fittings, EPDM gaskets
- Ferric Chloride - PVC fittings, EPDM gaskets
- Ferric Sulfate - PVC fittings, EPDM gaskets
- Hydrochloric Acid - PVC fittings, Viton gaskets
- Hydrofluoric Acid - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide - PVC fittings, Viton gaskets
- Peracetic Acid - 316SS fittings, Aflas gaskets
- Phosphoric Acid - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate - PVC fittings, EPDM gaskets
- Potassium Hydroxide - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Hypochlorite - PVC fittings, Viton gaskets
- Sodium Thiosulfate - PVC fittings, EPDM gaskets
- Sulfuric Acid - CPVC fittings, Viton gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
If your chemistry appears on that 1.9 SG list, call us at 866-418-1777 and we will spec the correct higher-SG vessel and gasket package rather than risk this tank. Confirm your full chemistry against the Chemical Compatibility Database, plan instrumentation with the level gauge selection guide, and mark the tank per the tank labeling and NFPA 704 signage guide.
