The Enduraplas 2500 Gallon Green Horizontal Sump Bottom Leg Tank ships with its steel support frame and is engineered to haul dense liquids down the road. The polyethylene tank carries a 1.9 specific gravity rating, which is what makes it a serious chemical and fertilizer hauler rather than a water-only tank. Filled with plain water it holds roughly 20,850 pounds; rated to its full 1.9 SG, the maximum contents weight reaches about 39,615 pounds. Tank dimensions are 130 inches long by 87 inches wide by 78 inches tall, giving an 87.0 x 130.0 inch footprint on the frame. See the technical drawing on this page for the sump-bottom profile, leg-frame layout, and the exact fitting sizes and locations.
Will it work for your load?
This is a horizontal leg tank with a sump bottom, so it drains toward a low point for cleaner offload and easier rinse-out between loads. The 1.9 SG rating means the wall thickness and frame are built for liquids heavier than water at this 2,500 gallon volume, which is the range applicators and nurse-tank operators look for. If you are still mapping volume to your trailer or rig, the Tank Sizing Calculator and Tank Sizing Guide help you match capacity to weight limits before you commit. Because this is a transport tank, our guides on applicator and leg tanks for fertilizer and DOT classification for farm-fleet utility tanks are worth reading before a horizontal leg tank like this goes on a public road. Fitting sizes and port locations are shown on the technical drawing and confirmed by phone before you order.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. Our resin reference lists it as HDLPE but flags it for verification, so confirm whether your tank is HDLPE or XLPE before putting it into chemical service. Compatibility always depends on resin, concentration, and temperature, so match every chemical to the OEM chemical-resistance chart for the specific concentration and operating temperature you run. Where a concentration is not specified below, confirm your operating range before committing.
Chemicals this tank's resin and SG rating support, with the fitting and gasket materials that pair with each, include: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM, concentration not specified), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM, concentration not specified), Sodium Bisulfate (PVC/PP, EPDM, concentration not specified), Sodium Bisulfite (PVC/PP, EPDM, concentration not specified), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM, concentration not specified), and Ozonated Water up to 10 PPM (PVC, EPDM). Fitting and gasket materials matter as much as the tank: the acids in this set that require Viton gaskets rather than the default EPDM are Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric, while Peracetic Acid needs Aflas and 316SS fittings. Putting an EPDM gasket on a Viton-required acid is a common and costly mistake. Start at our chemical compatibility hub to confirm your service.
Freight and how to order
This tank ships LTL freight from Neche, North Dakota, and freight is quoted live to your ZIP code rather than included in the list price. At roughly 20,850 pounds of water weight on a frame and a 130 x 87 inch footprint, this is a heavy single-piece LTL load, so pull an exact number with the Freight Cost Estimator before you order.
