Snyder Industries 40 Cubic Foot Capacity 45 Degree Plastic Cone Bottom Dry Hopper Bin

The Snyder Industries 40 Cubic Foot 45 Degree Plastic Cone Bottom Dry Hopper Bin (SKU SII-6370540N95402) is a 300 gallon closed-top vessel molded in High Density Linear Polyethylene, rated to a 1.5 specific gravity and a maximum contents temperature of 120 F / 48 C, and built to Snyder specification numbers 2285 and 2282.It stands 68 inches tall on a 48 x 53 inch footprint, carries a 12" lid, and ships as a bare tank with no stand.Empty it weighs 341 lb.The steep 45 degree cone is the defining feature: as a dry hopper bin it is built to fully evacuate powders and granules that bridge or hang up in a shallower 15 or 30 degree cone, and within its 1.5 SG rating it handles dense liquids the same way.See the technical drawing on this page for cone geometry and mounting dimensions.

Will it work for your material?

Start with weight, because a cone bottom with no stand transfers everything to whatever structure supports the flange.Filled with water this tank holds about 2,502 lb; at its full 1.5 SG rating the contents can reach roughly 3,753 lb.Your support ring, stand, or platform has to carry that plus the 341 lb tank.Because this is a cone bottom NO stand configuration, you supply the elevated support structure that gives the 45 degree cone room to drain into your pump, valve, or discharge point.Confirm your fitting layout before ordering, since this unit carries no factory outlet or fitting kit.For sizing math and support-load planning, use the Tank Sizing Calculator and the Tank Sizing Guide.

Chemical compatibility

This tank is molded in HDLPE and rated to 1.5 specific gravity per the Snyder Industries OEM chemical resistance chart.Compatibility is always concentration and temperature specific, so confirm your exact chemical, concentration, temperature, and both fitting and gasket materials before committing.Within the 1.5 SG rating, the Snyder chart supports service such as Acetic Acid at 60% (PP/PVC fittings), Aluminum Sulfate at 50%, Calcium Chloride at 40%, Ferrous Sulfate at 20%, Magnesium Chloride at 30%, and Sodium Carbonate at 30%, all with PVC fittings and EPDM gaskets, plus Ozonated Water up to 10 PPM on the same PVC/EPDM pairing.Two fluids sit comfortably inside the rating with margin to spare: DEF at 32.5% and Urea Solution at 50% both call for only a 1.35 SG tank, so this 1.5 SG bin is a strong fit for a DEF or urea program — note both want 316SS or PP/PVC fittings rather than plain PVC.Verify each against the Chemical Compatibility Database and the OEM chart for your operating temperature.

The mistake to avoid: under-rating specific gravity

The single most common error on a cone bottom is putting a heavy or aggressive chemical into a tank whose SG rating is too low.Several chemicals people try to store in a 1.5 SG tank actually require a higher 1.5 SG vessel, and on the oxidizers the gasket is the real failure point — not the tank wall.Those needing a 1.5 SG tank include Sulfuric Acid at 98% (CPVC fittings, Viton gaskets), Hydrochloric Acid at 37% (PVC/Viton), Sodium Hypochlorite under 16.5% (PVC/Viton), Hydrogen Peroxide at 50% (PVC/Viton), Phosphoric Acid at 85% (PVC/Viton), Peracetic Acid at 30% (316SS/Aflas), Ferric Chloride at 50% (PVC/EPDM), Ethylene Glycol (PVC/EPDM), and Potassium Hydroxide (PVC/EPDM).This 1.5 SG unit is not rated for those — step up to a 1.9 SG tank rather than compromise wall strength.When you do commit fittings, plan vent, fill, level, and drain penetrations deliberately using our guide on tank-top fitting placement, and if you are pulling from the cone with a centrifugal pump, review suction geometry and dry-run protection first.To compare cone angles, see the 15 vs 30 vs 45 degree selection guide and the 300 gallon cone bottom buyer's guide.
