The Snyder Industries 1000 Gallon Heavy Duty Cone Bottom Tank (SKU 5000000N51) is built for chemical service that demands continuous, gravity-assisted drainage. Molded from high density linear polyethylene in black and rated to a 1.9 specific gravity, this 1000 gallon cone tank stands 103 inches tall on a 64 x 64 inch footprint, with a 64 inch overall width. Read the 1.9 SG rating first: it means the tank wall is engineered to hold dense chemicals up to a maximum rated contents weight of 15,846 lb, well above the 8,340 lb a full load of plain water weighs. That margin is what lets you run concentrated acids and salts in this tank with confidence rather than guessing.
Will it work for your application
The cone-bottom geometry drains the tank fully toward a single low point, so settling solids, slurries, and batch chemistries clear out without a sump pump or manual rinse. The drawing for this tank shows three factory fittings:
- Flange outlet at the cone
- 18-inch PE threaded and vented fitting (the vent matters for fast load-in and load-out on a dense liquid - do not cap it without an alternate vent)
- Manway with 15-inch access for inspection and dosing
See the technical drawing on this page for fitting placement and the exact cone angle. Because a cone-bottom tank cannot stand on its own, plan on a matching stand or structural support sized for the full 15,846 lb rated load; our Cone Bottom Tank Stand Compatibility Matrix and the Tank Sizing Calculator will help you confirm the right base. If you are weighing this size against your batch volume, the 1000 Gallon Cone Bottom Tank Buyer's Guide walks through the trade-offs.
Chemical compatibility
This tank is HDLPE rated to 1.9 specific gravity, which is the heavy-duty ceiling for this 1000 gallon cone line - there is no higher-SG tank in this size to step up to, so anything denser (a concentrated ferric or sulfuric blend approaching 1.9) puts you at the top of the range. Verify your fluid's actual specific gravity against the 15,846 lb max rated contents weight before ordering. Compatibility below reflects our chemical-resistance data and is concentration- and temperature-specific - always match it against your actual conditions. Verified-compatible chemistries include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), magnesium chloride (30%), peracetic acid (30%), phosphoric acid (85%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (under 16.5%), sodium thiosulfate (40%), sulfuric acid (98%), urea solution (50%), zinc orthophosphate, and ozonated water (up to 10 PPM). Ozonated water is the one chemistry here without a dedicated detail page - check it on the main Chemical Compatibility Database.
Fittings, gaskets, and the mistake to avoid
The single most common error on a chemical cone tank is fitting and gasket material - the polyethylene wall may be compatible while the wrong valve or elastomer fails first. PVC fittings with EPDM gaskets suit aluminum sulfate, calcium chloride, ethylene glycol, ferric chloride, ferric sulfate, ferrous sulfate, magnesium chloride, polyaluminum chloride, potassium carbonate, potassium hydroxide, sodium carbonate, and sodium thiosulfate. Oxidizers and strong acids step up to Viton gaskets: hydrochloric acid, hydrogen peroxide, phosphoric acid, and sodium hypochlorite run PVC fittings with Viton, while hydrofluoric acid (48%) and hydrofluosilicic acid (26%) take PP or PP/PVC fittings with Viton gaskets - do not spec EPDM on those two by inference. Sulfuric acid (98%) needs CPVC fittings with Viton. The metal-and-specialty tier stands apart: peracetic acid (30%) requires 316SS fittings with Aflas gaskets - not Viton, not EPDM - while DEF runs 316SS with EPDM, and propylene glycol and zinc orthophosphate use PP or 316SS. Acetic acid, urea solution, sodium bisulfate, and sodium bisulfite use PP or combined PP/PVC fittings with EPDM. Confirm every chemistry against its detail page and the full Chemical Compatibility Database before ordering valves and gaskets.
