The Enduraplas 3000 Gallon Green Horizontal Sump Bottom Leg Tank arrives mounted in its steel frame and rated for a 1.9 specific gravity, which is what makes it a haul-and-store workhorse rather than a water-only tank. At 130 inches long, 87 inches wide, and 94 inches tall, it carries a full 3,000 gallons of water at roughly 25,020 pounds, and the polyethylene shell and frame are rated to support contents up to 47,538 pounds. That is roughly 22,518 pounds of headroom above a full water load, and it is the whole point of the 1.9 SG rating: at a dense fertilizer blend or heavy chemical you can reach the 47,538-pound structural ceiling before the tank is volumetrically full, so you size by weight, not just gallons. The sump bottom drains low so you empty the tank cleanly between loads, and the leg-tank geometry keeps the center of gravity manageable on a frame or applicator setup.
Will it work for your job?
Check three numbers against your application before you order. First, footprint: this horizontal leg tank occupies an 87.0 x 130.0 inch pad, so confirm your trailer deck, skid, or containment area clears it. Second, weight: a full water load is about 25,020 pounds and the maximum rated contents weight is 47,538 pounds, so verify your frame, axles, and lift equipment are rated above whatever your product weighs at its own density. Third, the 1.9 SG rating tells you how dense a liquid the tank wall is engineered to hold, but it does not tell you whether the resin resists your specific chemical. If you are sizing this for a fertilizer or solution program, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to weight, and our guide on fertilizer-blend tank stratification covers the mixing and field-verification practices that keep a dense blend from salting out. For DOT and trailer-scope questions on leg and applicator tanks, see our writeups on applicator and leg tanks for fertilizer and portable utility tank DOT classification.
Chemical compatibility
This tank is polyethylene with a 1.9 SG rating, but the exact resin designation in our records is not confirmed. Confirm the resin type with us before any chemical service, because that single fact, not the SG number, decides what the tank can hold long term. Every fitting and gasket call below is concentration- and temperature-specific, so always check the OEM chemical-resistance chart for your exact product, concentration, and operating temperature before committing. At 1.9 SG this tank already sits at the top of the standard polyethylene density tier, so there is no higher-SG alternative to step up to.
With that caveat, and within its 1.9 rating, this tank is compatible with these products at the listed concentrations, with the 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 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 fittings, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Match the fitting and gasket material to the product you are running, and confirm everything against the OEM chemical-resistance chart at your concentration and temperature. Our full chemical compatibility reference covers the rest.
The mistake to avoid
The expensive error on a tank this size is treating the 1.9 SG rating as if it covered chemical resistance. It does not. The rating only certifies that the wall and frame can carry a liquid up to 1.9 times the weight of water; whether your product attacks the polyethylene over time is a separate question answered by the resin type and the compatibility chart. Pair that with confirming the exact resin type on this specific tank, and you avoid both an overweight structural failure and slow chemical degradation. Then match the right fitting and gasket material from the list above to the product you are running, because the wrong gasket fails long before the tank does.
