The Snyder Industries 65 Gallon Heavy Duty Cone Bottom Mixing Tank is built for blending, dosing, and full-drain chemical service where you need every drop to evacuate through the cone. Molded in black High Density Linear Polyethylene with a 1.9 specific gravity rating, this 65-gallon cone bottom tank carries a wide chemical envelope and a heavier wall than the water tanks in the same footprint. It stands 31 inches tall on a 30 x 30 inch base, so it drops onto a matching stand or into a containment area without sprawling across your pad.
Will it work for your application?
Filled with water this tank weighs about 542 pounds; rated to its 1.9 specific gravity ceiling the contents can reach roughly 1,030 pounds. Plan the supporting stand and floor for the full 1,030 lb loaded condition, not the dry shell, that is 488 lb of headroom above the water-filled weight, which is exactly what the 1.9 SG rating buys you. The cone bottom geometry keeps solids and slurries moving toward the outlet instead of settling, which is why these cone tanks are a go-to for mixing and batching rather than static storage. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 65-gallon working volume against your batch size, and review the Cone Bottom Tank Stand Compatibility Matrix before you order a stand. Exact outlet and fitting locations are shown on the technical drawing on this page.
Chemical compatibility
This is an HDLPE tank with a 1.9 specific gravity rating, which gives it the density headroom to hold heavier acids and concentrated solutions that thinner tanks cannot. At 1.9 SG this is already the heaviest-duty density class Snyder offers in this size, so there is no higher-SG cone bottom to step up to and you are not under-spec'ing by choosing it. Compatibility always depends on the OEM chemical-resistance chart, which is concentration- and temperature-specific, so confirm your exact conditions before committing to a chemical. Within this resin and SG rating, common compatible chemicals include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Phosphoric Acid (85%, PVC, Viton), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sulfuric Acid (98%, CPVC, Viton), Peracetic Acid (30%, 316SS, Aflas), DEF (32.5%, 316SS, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). It also handles brines and glycols such as Calcium Chloride (40%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), and Ethylene Glycol (100%, PVC, EPDM), plus coagulants and treatment chemistries including Ferric Sulfate, Ferrous Sulfate, Polyaluminum Chloride, Sodium Bisulfate, Sodium Bisulfite, Sodium Carbonate, Sodium Thiosulfate, Potassium Carbonate, Potassium Hydroxide (saturated), and Zinc Orthophosphate. Each linked chemical page lists the verified fitting and gasket material for that exact concentration, and you can see the full per-chemical detail in the Chemical Compatibility Database.
The mistake to avoid
The most common error on a cone bottom mixing tank is matching the resin but not the gasket and fitting. The technical drawing shows where the ports are; the compatibility table tells you what material to thread into them, and the two are independent decisions. Default PVC fittings with EPDM gaskets cover the brines, glycols, and many of the salts, but the oxidizers move you to Viton: Sodium Hypochlorite, Hydrogen Peroxide, Phosphoric Acid, Sulfuric Acid, and the Hydrofluoric and Hydrofluosilicic acids in the pack all call for Viton, while DEF and Peracetic Acid call for 316SS, not the default trim. Match the trim to your specific chemical, and review the level-gauge selection guide and the fertilizer-blend stratification guide if you are blending or dosing.
