The Enduraplas 1000 Gallon White Horizontal Sump Bottom Leg Tank with Frame is a 1000-gallon horizontal leg tank built for transport and field draindown. It measures 94 inches long by 60 inches wide by 71 inches tall, molded in natural white polyethylene, and carries a 1.9 specific gravity rating - heavy enough to run dense ag and water-treatment liquids, not just water. The sump bottom and integrated frame are reflected in the product name: the frame lets you skid-mount or trailer it for a portable nurse or applicator setup. For exact sump and frame detail, see the technical drawing on this page.
Will it work for your job
Sizing comes down to what you are hauling. Full of water, this 1000 gallon horizontal leg tank weighs about 8,340 lb. The 1.9 SG rating means it is engineered to carry contents up to roughly 15,846 lb - so a 1.9 SG fluid at full volume runs near that ceiling, while water uses only about half of it. That headroom is what lets it hold heavier-than-water fertilizer blends and treatment chemistries at full volume without overstressing the wall, but it is only usable if your trailer or skid is rated for about 15,846 lb of contents plus the tank and frame tare. Confirm your loaded weight before you fill, and use the Tank Sizing Calculator and Tank Sizing Guide to match capacity to your route and pump. The footprint is 60.0 x 94.0 inches, so verify it sits inside your frame rails or containment pad. For fitting locations, sump detail, and frame dimensions, see the technical drawing on this page.
Chemical compatibility
This is a high-strength polyethylene leg tank rated to 1.9 specific gravity. The resin is reported as HDLPE - confirm HDLPE versus XLPE before any chemical service, since crosslinked and linear polyethylene behave differently with aggressive media; call 866-418-1777 to verify linear versus crosslinked PE before committing to any acid haul, as the chart assumptions change with resin. Compatibility below is per the OEM chemical-resistance chart and is concentration- and temperature-specific; always match your exact concentration and service temperature before committing the tank.
Commonly run in this style of 1.9 SG tank with the noted 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), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Watch the exceptions to the standard PVC fitting + EPDM gasket setup: the chart calls for Viton gaskets on Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric Acid; Aflas gaskets with 316SS on Peracetic Acid; CPVC fittings on 98% Sulfuric Acid; and 316SS fittings on DEF, Peracetic Acid, Propylene Glycol, and Zinc Orthophosphate. Matching the wrong elastomer or fitting alloy is the most common mistake on a chemical haul tank. See the OEM chemical-resistance chart and our chemical compatibility reference, and confirm your specific concentration and temperature.
The mistake to avoid
Do not undersize the trailer or skid for the 1.9 SG rating. People size to water weight, then load a dense fertilizer or DEF blend and exceed the contents weight the structure assumes. The frame and legs are part of the rating system - mount and strap the tank as designed, and recheck loaded weight any time you switch to a heavier product. DEF is one of the clean fits here: at 32.5% it runs with 316SS fittings and EPDM gaskets, and its modest density sits well inside the 1.9 SG envelope. If you are spec'ing this for a portable applicator or nurse setup, our guide on applicator and leg tanks for fertilizer covers DOT non-roadable trailer scope, the portable utility tank guide explains the 49 CFR 173.5 farm exemption, and the fertilizer-blend stratification guide covers mixing protocol so a dense blend does not salt out and run off-spec.
