The Enduraplas 2500 Gallon Green Horizontal Sump Bottom Leg Tank is a 1.9 specific-gravity-rated polyethylene horizontal tank built to haul dense agricultural and industrial liquids on a transport skid or applicator chassis. It holds 2,500 gallons, measures 77 inches high by 87 inches wide by 130 inches long, and rides on integral legs with a sump-bottom design. The 1.9 SG rating is the structural headline here: it is engineered to carry liquids up to 1.9 times the weight of water, which is why fertilizer blends, brines, and heavy solutions belong on a tank like this rather than on a standard 1.0 or 1.5 SG vessel. Buyers searching for an Enduraplas horizontal leg tank in the 2500 gallon range land here for exactly that reason.
Will it work for your load?
Run the weight before you commit. Full of water, this tank carries 20,850 pounds of contents. At the maximum rated contents weight the tank is engineered for, it holds up to 39,615 pounds of liquid - that ceiling reflects the 1.9 SG rating and is the number that matters when you are hauling anything denser than water. Confirm your liquid's specific gravity stays at or below 1.9 at your fill volume; the 39,615 lb figure is the limit, not a target. The 87.0 x 130.0 inch footprint is what you need to verify against your trailer or skid deck. Note that fitting size, outlet, and bulkhead configuration are not specified in our catalog for this SKU - confirm what comes installed before you match the fitting and gasket materials listed below. If you are deciding between sizes, the Tank Sizing Calculator and the Tank Sizing Guide walk you through matching capacity, weight, and footprint to your hauling setup before you buy.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The resin is recorded as HDLPE (unconfirmed); for anything beyond water service, get written resin confirmation - HDLPE versus XLPE - from us before filling, because the resin, not the SG rating, governs long-term chemical resistance. Compatibility below is drawn from the OEM chemical-resistance chart, which is concentration- and temperature-specific; match your real-world concentration and operating temperature to that chart before filling.
Liquids compatible with this tank at the listed concentrations 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 fittings, 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), Magnesium Chloride at 30% (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide at saturated strength (PVC, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Thiosulfate at 40% (PVC, EPDM), Urea Solution at 50% (PP/PVC, EPDM), Polyaluminum Chloride (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), and Zinc Orthophosphate (PP/316SS, EPDM).
Several aggressive acids and oxidizers call for Viton or Aflas gaskets rather than EPDM, and that gasket choice is the mistake to avoid on this tank - the wrong elastomer fails long before the polyethylene wall does. These include 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), Phosphoric Acid at 85% (PVC, Viton), Sodium Hypochlorite below 16.5% (PVC, Viton), Sulfuric Acid at 98% (CPVC fittings, Viton), Peracetic Acid at 30% (316SS, Aflas), and ozonated water up to 10 PPM (PVC, EPDM). For the full picture across every liquid, see the chemical compatibility resource and confirm your exact concentration and temperature against the OEM chart.
Freight
This is a heavy, oversized leg tank that ships LTL freight, quoted live to your ZIP. It ships from the plant in Neche, ND - the nearest named shipping point for this tank. If you are planning a fertilizer or DOT non-roadable trailer build, the guides on applicator and leg tanks for fertilizer, portable utility tank DOT classification, and fertilizer-blend tank stratification are worth reading before you spec the build. Get an exact freight number with the Freight Cost Estimator, and call 866-418-1777 to confirm fitting placement and lead time before you order.
