The Snyder Industries 3000 Gallon Heavy Duty Cone Bottom Tank (SKU 8360000N51) is a black, high-density linear polyethylene cone tank built for full-drain chemical service, with a 1.9 specific gravity rating that lets it hold dense process chemistry most standard tanks cannot. It stands 120 inches tall on a 95 x 95 inch footprint and discharges completely through its conical base, which is exactly why operators dosing settling chemistries reach for a cone tank over a flat-bottom vertical. Whether you are sizing a cone bottom tank for batch mixing, dosing, or sediment-free transfer, the heavy-duty wall and rated capacity give you room to run aggressive chemistry without derating the vessel.
Will this tank work for your application?
At 3000 gallons, plain water fills this tank to roughly 25,020 pounds. Because it carries a 1.9 specific gravity rating, the vessel is engineered for contents weighing up to 47,538 pounds at full capacity, so you can run liquids nearly twice as dense as water without exceeding the design limit. The 1.9 SG rating is the heavy-duty tier for this cone tank, so if you need more capacity, size up in gallons rather than searching for a denser-rated option. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm your fill weight against the contents you are storing. Factory fittings on this model include a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for entry, gauging, and venting; these are the tank-side connections, and the wetted fitting and gasket materials listed in the chart below are what you spec into them. See the technical drawing on this page for fitting placement and exact dimensions before you finalize plumbing.
Chemical compatibility
This is an HDLPE vessel rated to 1.9 specific gravity, which is what makes it suitable for heavy chemical duty. The conical base is also the reason it suits settling chemistries like ferric chloride, ferric sulfate, ferrous sulfate, aluminum sulfate, and polyaluminum chloride: solids drain instead of accumulating on a flat floor. Always match your fitting and gasket materials to the chemical, not just the tank wall. Based on the OEM chemical-resistance chart - which is concentration- and temperature-specific - this tank is rated for the following at the listed concentrations:
- 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
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - 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 Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (under 16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Confirm your exact chemical, concentration, and temperature against the OEM chart and our Chemical Compatibility Database before ordering. The mistake to avoid on a heavy-duty cone tank is defaulting every connection to PVC and EPDM. Most of the chemistries above are fine on PVC/EPDM, but the exceptions bite: sulfuric acid (98%) needs CPVC fittings, DEF and peracetic acid need 316SS fittings, the acid group - hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric - needs Viton gaskets, and peracetic acid alone needs Aflas. Match the seal and the wetted fitting to the chemical every time.
Stand, freight, and ordering
A cone bottom tank discharges fully through its conical base, so it must sit in a matching steel stand - and that stand and its pad must be rated to carry the full 47,538 lb maximum contents weight concentrated on the 95 x 95 inch footprint. Check the Cone Bottom Tank Stand Compatibility Matrix for the right fit, and review the 3000 Gallon 15 Degree Cone Bottom Tank buyer's guide and 3000 Gallon 30 Degree Cone Bottom Tank guide to compare cone angles before you buy. If your install also involves spill containment, the Snyder Captor Plus 110% Containment vs UL-142 / SPCC comparison walks through the regulatory side.
