The Snyder Industries 190 Gallon Flowmaster Viscous Hopper Bin Tank (SKU SII-6370425N95402) is a specialty bin built for thick, heavy, slow-moving material - the kind of product that won't drain cleanly out of a flat-bottom tank. Its hopper geometry funnels viscous contents toward the outlet, and the 1.9 specific gravity rating means it is engineered to hold contents far denser than water. This is a Snyder polyethylene tank, white, standing 55 inches tall on a 48 x 45 inch footprint. If you have been searching for a heavy-duty white plastic tank or a low-profile Snyder bin for dense product, this is the unit built for that load.
Will it work for your material?
The number that matters most on a viscous hopper bin is the specific gravity rating. This tank carries a 1.9 SG rating, so it is built for dense, heavy product - not just water. At a full 190 gallons of plain water the contents weigh about 1,585 pounds, but the tank is rated to carry up to 3,011 pounds of contents at its maximum density. Here is the plain-language version: 1.9 SG is roughly the density of a heavy slurry or a concentrated chemical. If your material is near water weight (1.0 SG) you have full headroom and can fill the entire 190 gallons. If it is denser, the 3,011-pound ceiling - not the gallon mark - caps how full you should run it. Confirm your material's specific gravity falls at or under 1.9 before you commit, and verify the dimensions (55 in tall, 48 x 45 in footprint) clear your support stand and any conveyor or fill point above it. Use the Tank Sizing Calculator to confirm working volume for your fill schedule, and the Tank Sizing Guide to match capacity and footprint to the job. For dense, thermally-expanding contents, the Snyder freeboard-sizing guide walks through how SG and thermal expansion set the real usable volume versus the 190-gallon nameplate.
Confirm the outlet before you buy fittings
Outlet size, fitting thread, and gasket material are not listed for this unit, and on a viscous bin the outlet diameter is what drives your drain rate - so do not order mating hardware until it is confirmed. See the technical drawing on this page for the outlet location and hopper angle, and call 866-418-1777 to confirm the exact outlet size and thread before you specify valves or plumbing. Spending a minute on that call up front saves a return later.
Mounting and the mistake to avoid
A hopper bin needs full support under the cone and a level base under the stand or skirt - this is not a tank you set on bare ground. With up to 3,011 pounds of dense contents distributed over a 48 x 45 inch footprint, plus the tank's own weight, the pad and stand carry real, concentrated load - start your foundation spec from that 3,011-pound contents figure rather than a guess. The most common mistake on a viscous bin is treating the 1.9 SG rating as optional and filling it with something heavier than the tank was built to hold; the rating is the ceiling, not a suggestion. If your material exceeds 1.9 SG, this is the wrong tank for the job - call 866-418-1777 rather than overfill it. If you are pouring a foundation, the concrete pad sizing guide covers the ACI framework for above-ground polyethylene tanks.
