The Snyder Industries 2000 Gallon Vertical Double Wall Storage Tank is a tank-within-a-tank: an inner vessel rated to a 1.9 specific gravity carries the liquid while the molded outer wall provides built-in secondary containment. At 2000 gallons it stands 103 inches tall on a 102 by 102 inch footprint, finished in white. If you are sizing a vertical double wall tank that needs spill protection for a dense liquid without pouring a separate containment basin, this is the unit that earns its place. A note on the data: the catalog material field reads cross-linked polyethylene, while the model name references HDLPE and a sulfuric-acid resin - linear and cross-linked are different resins with different chemical behavior, so confirm the exact resin in writing before any chemical service rather than assuming from the listing.
Reading the 1.9 SG rating
The number that matters most here is the 1.9 specific gravity rating, and it governs density only: it tells you the inner tank wall is engineered to bear contents weighing up to 1.9 times the weight of water. Full of plain water this tank weighs roughly 16,680 lbs, but the inner vessel is rated to a maximum contents weight of about 31,692 lbs. Across 2000 gallons that works out to a ceiling near 15.8 lbs per gallon - check your stored product's per-gallon weight against that figure, and any liquid above it exceeds the rating regardless of compatibility. Because 1.9 is the upper rating, a buyer storing a 1.0 to 1.5 SG product is carrying substantial unused structural margin (water-full 16,680 lbs against 31,692 lbs rated), which is exactly why this tank tolerates dense service and density swings. One caution: specific gravity tells you the wall can carry the weight; it does not establish chemical compatibility.
Sizing and footprint
Plan the pad for the 102 by 102 inch footprint and the 103 inch overall height, and spec the concrete and approaches for a loaded weight that can run to roughly 31,692 lbs at maximum rated contents. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm the working volume you can actually use once you account for freeboard and thermal expansion; the Snyder Captor double-wall freeboard sizing guide works through that math in detail. For containment-code context, the SPCC 40 CFR 112 compliance walkthrough covers where this double wall style fits a containment plan, and the 2000 gallon vertical storage tank comparison shows how it lines up across brands.
The mistake to avoid
The most common error on a tank like this is treating the 1.9 SG rating as a blanket green light for any liquid. It is not - the rating governs weight, while suitability for a given product is a separate question you must confirm for your specific resin, concentration, and temperature. On a double wall tank that interface runs deeper than the wall: the bulkhead fitting and gasket material are the real compatibility chokepoint, and a wall rated correctly is moot if the gasket fails. This listing carries no fitting or gasket data, so we will spec those materials on quote for your exact chemistry. The second mistake is undersizing the pad or the freight equipment for a loaded weight north of 31,000 lbs. See the technical drawing on this page for the dimensional callouts and fitting layout before you finalize plumbing and tie-ins.
