The Snyder Industries 250 Gallon Vertical Chemical Storage Tank is built for liquid chemical service, not just water. It carries a 1.9 specific gravity rating, the heaviest-density configuration we list in this size, which is the spec that matters most when you are storing something denser than water. At 64 inches tall on a 36 x 36 inch square footprint, it holds 250 gallons of polyethylene-walled capacity in white. As a Snyder vertical storage tank, it is molded from polyethylene at the company's Merced, California plant.
Will it work for your application?
The 1.9 SG rating means this tank is engineered to hold contents up to 1.9 times the density of water. Filled with plain water, the contents weigh about 2,085 pounds; at the full rated 1.9 specific gravity, the tank is built to carry up to roughly 3,962 pounds of contents. That headroom is why this size shows up so often when people search for a 250 gallon vertical tank for heavier chemistries rather than a water-only drum. Plan for a level pad at least 36 x 36 inches under the square base, and remember the 36-inch footprint only clears a standard 36-inch doorway laid on its side. The standard fitting package shown on the technical drawing on this page includes a flange, an 18-inch PE threaded/vented fitting, and a manway with a 15-inch access opening for filling, inspection, and cleaning. Confirm your level gauge, fill line, and any agitator or mixer hardware fit through that 15-inch opening before you order.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin in our records is listed as high-density linear polyethylene (HDLPE) but carries a question mark, so confirm HDLPE versus crosslinked (XLPE) construction with us before committing the tank to chemical service. Compatibility always depends on the chemical, its concentration, and temperature, so check the chemical-resistance data for your exact conditions. Based on that data, this tank suits a wide range of chemistries when paired with the correct fittings and gaskets, for example:
- Sodium hypochlorite at <16.5% with PVC fittings and Viton gaskets
- Sulfuric acid at 98% with CPVC fittings and Viton gaskets
- Hydrochloric acid at 37% with PVC fittings and Viton gaskets
- Ferric chloride at 50% with PVC fittings and EPDM gaskets
- Aluminum sulfate at 50% with PVC fittings and EPDM gaskets
- Phosphoric acid at 85% with PVC fittings and Viton gaskets
- Hydrogen peroxide at 50% with PVC fittings and Viton gaskets
- DEF (diesel exhaust fluid) at 32.5% with 316 stainless fittings and EPDM gaskets
- Peracetic acid at 30% with 316 stainless fittings and Aflas gaskets
- Potassium hydroxide at saturated concentration with PVC fittings and EPDM gaskets
Other verified chemistries for this tank include acetic acid (60%), calcium chloride (40%), ethylene glycol (100%), ferric sulfate (60%) and ferrous sulfate (20%), hydrofluoric (48%) and hydrofluosilicic acid (26%, each with Viton), magnesium chloride (30%), polyaluminum chloride, potassium carbonate (50%) and sodium carbonate (30%), sodium bisulfate, sodium bisulfite, sodium thiosulfate (40%), urea solution (50%), propylene glycol, and zinc orthophosphate. Ozonated water up to 10 PPM is also compatible with PVC fittings and EPDM gaskets, though we do not yet have a dedicated page for it, so call us for service-specific guidance. Match each chemical to the fitting and gasket material called out for it, and see our full Chemical Compatibility Database for concentration- and temperature-specific guidance.
The mistake to avoid
Do not assume any polyethylene tank handles your chemistry, and do not reuse fittings or gaskets from a different application. The single most common error on a chemical install is mismatching fitting and gasket materials. The same tank wants Viton on sodium hypochlorite and sulfuric acid but EPDM on aluminum sulfate, and DEF and peracetic acid are the two chemistries here that reject PVC outright and require 316 stainless fittings. Confirm the resin (HDLPE versus XLPE), confirm your concentration against the chart, and spec the correct fitting and gasket before you order. For help choosing the right capacity and configuration, use the Tank Sizing Calculator and the Tank Sizing Guide.
