The Enduraplas 1000 Gallon Yellow Horizontal Sump Bottom Leg Tank is a polyethylene transport-and-process tank built for heavy liquids, with a 1.9 specific-gravity rating that puts it at the top of what a poly leg tank handles. The sump bottom drains the tank toward a single low point, so it empties completely between loads instead of carrying a heel of residual product, which matters for hauling dead weight and for clean changeovers when you switch chemicals. The molded legs let the unit sit stable on a skid, trailer deck, or applicator frame. At 94 inches long, 60 inches wide, and 70 inches tall with a 60.0 x 94.0 inch footprint, this is a horizontal leg tank sized for a 1000 gallon haul without going to steel.
Will this tank work for your job?
The 1.9 SG rating is the number to read first. Filled with plain water, the contents weigh about 8,340 lbs; at the tank's maximum rated specific gravity the contents can run up to roughly 15,846 lbs. That gap of more than 7,500 lbs is your axle margin: water is 1.0, but many fertilizers, brines, and acids are far denser, and the 1.9 rating tells you this tank is engineered to carry them without overstressing the wall. Match your actual liquid's specific gravity to that ceiling before you fill. If you are sizing a trailer or applicator around the loaded weight, run the numbers through the Tank Sizing Calculator and read the Tank Sizing Guide so the frame and axles are rated for the full load, not the empty tank.
Chemical compatibility
This tank is polyethylene with a 1.9 specific-gravity rating. The resin is listed as HDLPE but flagged for confirmation, so before you commit this tank to any chemical service, confirm the exact resin against the OEM chemical-resistance chart and, if you have any doubt, call 866-418-1777 first. That is a hard pre-purchase step, not a footnote, on a 1.9-SG chemical tank. Compatibility below is concentration- and temperature-specific; verify your exact concentration and operating temperature against the OEM chart for any chemical you store.
Within the 1.9 SG rating, this tank is listed compatible with a wide range of process chemicals, each with its own recommended fitting and gasket materials: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, 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), and Zinc Orthophosphate (PP/316SS, EPDM); additionally listed compatible is Ozonated Water (up to 10 PPM, PVC, EPDM). Notice that fitting and gasket material changes with the chemical: sodium hypochlorite and the strong acids call for Viton, peracetic acid wants Aflas, and DEF wants 316 stainless. Specifying the wrong gasket is the most common mistake on a chemical tank, so use the per-chemical pages and the full chemical compatibility reference before you order fittings.
Freight and ordering
This 1000 gallon horizontal leg tank ships LTL freight from the Enduraplas plant in Neche, North Dakota, quoted live to your ZIP code. Because the loaded weight and the legs make this an oversize freight item, use the Freight Cost Estimator for freight quoted to your address, or call 866-418-1777 and we will quote it for you. If you are putting this tank into fertilizer or applicator service, the guide on applicator and leg tanks for fertilizer and the reference on fertilizer-blend tank stratification are worth reading before you haul. Listed at the price shown, freight quoted separately to your ZIP.
