The Snyder Industries 100 Gallon HDLPE Vertical Chemical Storage Tank is built for serious chemical service: a 1.9 specific-gravity rating across a compact 30-inch by 30-inch footprint that stands 41 inches tall. The high-density linear polyethylene (HDLPE) shell and the 1.9 SG wall thickness are what separate this tank from a general-purpose 100-gallon vertical storage tank - it is rated to hold dense, aggressive liquids, not just water. If you are sizing a chemical day tank, a metering-skid feed, or a small bulk storage point, this is the white Snyder vertical tank built for the job.
Will it work for your liquid?
Start with weight, because that drives the slab and the lift. Filled with water this tank carries 834 lb; at its full 1.9 SG rating the contents alone reach 1,585 lb. Confirm your floor or pad supports that loaded weight over the 30 x 30 footprint before you set it, and plan overhead clearance above the 41-inch top for the manway lid swing and the fill connection. The tank comes with a top flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for filling, mixing-equipment mounting, and cleanout. Match your plumbing and instrumentation to those existing connections rather than drilling new penetrations. For level monitoring on a chemical feed, our guide on selecting tank level gauges for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options. See the technical drawing on this page for exact fitting placement, and run your numbers through the Tank Sizing Calculator or the Tank Sizing Guide if you are still settling on capacity.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The catalog lists the resin as HDLPE - because that designation carries a question mark in our source data, confirm HDLPE versus XLPE (cross-linked) construction with us before committing it to chemical service, since the two resins differ in chemical resistance. The materials called out below are the bulkhead-fitting and gasket materials you install into the existing flange and 18-inch threaded port - not fittings that ship pre-installed on the tank. Every pairing is referenced against the OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact concentration and operating temperature before ordering.
Liquids charted for storage in this tank include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), ethylene glycol (100%, PVC, EPDM), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), ferrous sulfate (20%, PVC, EPDM), hydrochloric acid (37%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), magnesium chloride (30%, PVC, EPDM), peracetic acid (30%, 316SS, Aflas), phosphoric acid (85%, PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate (30%, PVC, EPDM), sodium hypochlorite (under 16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). Note that fitting and gasket materials change by chemical - sodium hypochlorite and the strong acids call for Viton, peracetic acid calls for Aflas, and DEF wants 316 stainless - so spec the connections to the chemical, not the other way around. Full concentration and temperature limits live in the Chemical Compatibility Database.
The mistake to avoid
The most common error on a tank like this is putting a dense chemical into a tank rated below its specific gravity. This shell is rated to 1.9 SG, which covers most concentrated acids and brines - but always check that your product's SG and concentration fall inside the chart limits above before you fill. The second mistake is gasket material: dropping an EPDM gasket onto a sodium hypochlorite or sulfuric acid connection will fail, while those services need Viton. Get the resin confirmation (HDLPE vs XLPE) and the fitting/gasket pairing right up front and this tank will run for years.
