The Snyder Industries 30 Gallon Black Heavy Duty Cone Bottom Mixing Tank is built for batch chemical work where you need the tank to fully drain and dose without leaving a heel in the bottom. It measures 27 inches across the base and 20 inches tall, with a 27 x 27 inch footprint, and carries a 1.9 specific gravity rating molded in heavy-duty High Density Linear Polyethylene (HDLPE) and finished in black. That 1.9 SG rating is the headline number for chemical buyers: it means the wall thickness is rated to hold liquids up to 1.9 times the weight of water, which is what lets this 30 gallon cone bottom tank carry dense acids and concentrated solutions a standard water-grade tank cannot. The cone outlet sits at the apex of the cone, so contents gravity-drain to a single low point for clean batch turnover.
Will it work for your application
Filled with plain water this tank holds about 250 pounds, and at its 1.9 SG rating it is engineered for up to roughly 475 pounds of contents. Use those two numbers when you spec a stand or platform: the cone bottom design means this tank must sit in a matching cone-bottom stand, not flat on the ground, so the full loaded weight transfers to the stand legs. The 27 x 27 inch footprint and 20 inch height keep it compact enough for indoor day-tank and mix-station duty. If you are not sure which size fits your batch volume, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide, and for stand pairing see our Cone Bottom Tank Stand Compatibility Matrix.
Chemical compatibility
This is an HDLPE tank with a 1.9 specific gravity rating. Verify your chemical is compatible with HDLPE specifically, at your concentration and temperature, before putting this tank into service, and always pair the fitting and gasket material to the chemical rather than to each other. Verify every selection against the OEM chemical-resistance chart at your specific concentration and temperature. Chemicals this resin and SG rating commonly handle, with their typical fitting and gasket materials, 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). Watch the gasket pairings: chlorine-bearing and oxidizing chemicals such as sodium hypochlorite, hydrogen peroxide, and sulfuric acid call for Viton or CPVC, not the EPDM used for most salts. Ozonated Water is the one oxidizer above that pairs with EPDM, and only because its concentration ceiling is a low 10 PPM, so do not generalize that EPDM-with-ozone pairing to any stronger oxidizer. Full details are in our Chemical Compatibility Database.
The mistake to avoid
The most common error on a cone bottom chemical tank is matching the gasket to the fitting instead of to the chemical. EPDM is correct for the carbonates, chlorides, and glycols above, but it will fail fast on the oxidizers, which is why this list specifies Viton for sodium hypochlorite, peroxide, and the strong acids, and Aflas for peracetic acid. Pulling the wrong gasket is the difference between a sealed system and a slow chemical leak. Confirm the 1.9 SG rating actually covers your product before you fill it; if your chemical exceeds a 1.9 specific gravity, this tank is not rated for it, so call 866-418-1777 and we will source a higher-rated tank. For dosing accuracy, the Tank Level Gauge Selection guide walks through gauge types for chemical service, and if you are blending fertilizer, our tank stratification guide covers keeping a blend from layering out.

This Snyder cone bottom tank ships LTL freight from the nearest of our Albertville, AL, Lincoln, NE, and Merced, CA plants, with the rate quoted live to your ZIP. Shipping from the closest plant keeps freight down: a West Coast buyer ships out of Merced, a Southeast buyer out of Albertville, instead of paying cross-country freight from a single warehouse.
