The Snyder Industries 600 Gallon 45-Degree Flowmaster Viscous Hopper Bin is a steep-cone polyethylene storage and discharge tank built for thick, heavy, slow-moving liquids that need to gravity-drain clean. It measures 107 inches tall on a 48 inch wide by 45 inch deep footprint, holds 600 gallons, and carries a 1.9 specific gravity rating - the highest standard wall rating Snyder makes - so this white poly tank is engineered around dense, viscous contents from the start rather than plain water.
Will it work for your contents?
The 1.9 specific gravity rating is the number to plan around. Full of water (SG 1.0), the contents weigh about 5,004 pounds. At the tank's maximum rated 1.9 SG, the contents can weigh up to 9,508 pounds - that headroom is the whole point of the Flowmaster line, because viscous bulk materials like slurries, heavy concentrates, and high-density liquids routinely run well above water density. The 45-degree cone is steeper than a standard cone-bottom tank, which is what lets thick, sticky product slide down and discharge instead of bridging and hanging up on the slope. Verify your material's specific gravity and viscosity against the 1.9 rating before you commit; if your contents exceed 1.9 SG you need a higher-rated tank, not this one. Outlet size, port locations, and discharge geometry are on the technical drawing on this page - confirm the outlet and gasket/fitting material against your discharge plumbing before you order, and check the cone and outlet detail against your stand or hopper frame, since a 45-degree viscous hopper needs proper elevated support to drain.
Sizing and weight planning
Plan the structure for the loaded weight, not the empty tank. The swing is large and it drives the whole design: SG 1.0 water = 5,004 lb, while SG 1.9 rated max = 9,508 lb - a roughly 4,500 pound difference concentrated on the 48.0 x 45.0 inch base. The support frame, legs, and pad have to carry real tonnage on a small footprint. Run your numbers through the Tank Sizing Calculator and review the Tank Sizing Guide to confirm the 600-gallon capacity matches your batch volume and turnover. Because this is an elevated hopper that drains by gravity, the foundation under the stand matters - the concrete pad sizing framework walks through the pad and bearing-load thinking for a tall above-ground polyethylene tank like this one.
The mistake to avoid
The common error with a high-SG viscous hopper is treating it like a water tank and under-building the support or over-filling past the density rating. This is a 600-gallon white poly tank rated to 1.9 SG - that rating governs both how much your contents can weigh and whether the polyethylene wall is the right choice. Match your product's density to the 1.9 limit, and understand how density, freeboard, and the real volume you can actually use interact - the Snyder freeboard and ASTM D1998 sizing guide works through exactly that reasoning for a Snyder tank. If you are storing a chemical or concentrate, confirm the resin's compatibility with that specific material before filling. The steep 45-degree cone only earns its keep when the tank is mounted on a stand sized for a near-five-ton loaded weight and the discharge is plumbed to clear thick product.
