The Snyder Industries 1000 Gallon Heavy Duty Cone Bottom Tank (SKU 1890000N51) is built for full-drain chemical batching, mixing, and dosing where you can't leave product sitting in the bottom. It's molded in black High Density Linear Polyethylene with a 1.9 specific gravity rating, the heavy-duty wall structure that lets you fill it with dense chemistry rather than just water. The tank holds 1000 gallons, stands 66 inches tall, and sits on an 86 x 86 inch footprint, so plan your stand and clearance around that 86-inch outside dimension before you order.
Will this 1000 gallon cone bottom tank work for your application?
The cone bottom drains completely, which is what separates this from a flat-bottom vertical when you're running a slurry, a settling chemical, or any product you need to evacuate clean between batches. The molded fittings are:
- 10" PE threaded/vented opening - the large vent matters for fast-fill venting on a dosing tank
- Fill cap with 7" access
- Flange
- Top fitting
See the technical drawing on this page for fitting locations and the exact cone geometry. Because the cone holds the load off the ground, this tank requires a matching cone-bottom stand; it does not free-stand. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the size against your batch volume, and check stand pairing in our Cone Bottom Tank Stand Compatibility Matrix and the 1000 Gallon 45 Degree Cone Bottom Tank buyer's guide.
Weight, sizing, and the mistake to avoid
Full of water this tank carries about 8,340 lbs; at its 1.9 SG rating the maximum rated contents weight climbs to 15,846 lbs. That spread is the single most common mistake buyers make on a cone tank: sizing the stand and pad for a water number when you're storing something heavier. Match the stand's rating to your actual product's specific gravity, not to water. The 1.9 SG rating is what makes this tank suitable for dense chemistry, but the resin still has limits - read the OEM chemical-resistance chart for your specific product before committing.
Chemical compatibility
This tank is molded from HDLPE with a 1.9 specific gravity rating. The chemicals below are supported with the fitting and gasket materials shown; always verify against the OEM chemical-resistance chart for your exact concentration and temperature, since compatibility is concentration- and temperature-specific. Recommended pairings include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). The gasket choice matters as much as the tank: EPDM covers the salts and glycols, Viton is called out for the strong acids and oxidizers (hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sulfuric, and sodium hypochlorite), and Aflas specifically for peracetic acid. Match your fitting and gasket to the chemical, then confirm in our Chemical Compatibility Database.
