The Enduraplas 1200 Gallon Green Horizontal Sump Bottom Leg Tank ships on its own integrated frame and is built to move dense liquid down the road. The horizontal leg body sits level on its frame, and the sump bottom drains the tank fully so you are not leaving product behind at the end of a run. It holds 1,200 gallons, stands 64 inches tall, and lays out to a 70 x 102 inch footprint of green polyethylene rated to a specific gravity of 1.9. It ships from a single Enduraplas plant in Neche, ND, so if you are in a southern or coastal ZIP, run the Freight Estimator early - LTL on a horizontal tank this size moves the total materially.
Will it work for your job?
This is a polyethylene horizontal leg tank with a 1.9 specific gravity rating, which is what lets it carry dense agricultural and industrial liquids rather than just water. Filled with water at SG 1.0, the contents weigh about 10,008 pounds; the tank is rated to carry up to 19,015 pounds of contents, which works out to a fill density of SG 1.9. The practical meaning: you can fill all 1,200 gallons of any liquid up to SG 1.9 without derating volume - most SG-rated tanks force you to give back capacity as density climbs, and this one does not. Confirm your liquid's specific gravity against that 1.9 rating before you fill; that single number is the difference between a tank that lasts and one that fatigues early. The sump bottom is the detail haulers care about: it drains the tank to near-empty so you can switch products or store the unit dry. Fitting and outlet locations are not listed in our spec data for this unit - call 866-418-1777 to confirm sump and port placement against your transfer pump and trailer layout before ordering.
Chemical compatibility
This tank is polyethylene with a 1.9 specific gravity rating. The resin grade is not confirmed in our data, so confirm the exact polyethylene construction with us before putting the tank into chemical service - cross-linked and linear polyethylene resist different chemistries, and that distinction governs which liquids are safe. The compatibility below comes from the OEM chemical-resistance chart and is concentration- and temperature-specific, so match your actual conditions before committing.
Within its 1.9 SG rating, this tank handles a broad slate of agricultural and water-treatment chemistry: 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, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). The fitting and gasket material is not the same across the chart - watch these exceptions before you plumb the tank:
- Viton gaskets: Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Phosphoric Acid, Sodium Hypochlorite, and Sulfuric Acid.
- Aflas gaskets: Peracetic Acid (with 316SS fittings).
- CPVC fittings: Sulfuric Acid (98%).
Pull the right elastomer and fitting material for your product; the wrong gasket fails long before the tank does. See the full chemical compatibility reference to cross-check your concentration and temperature.
Sizing and a mistake to avoid
The biggest haul-tank error is plumbing and ballasting the trailer for water weight and then loading a denser product. Use the Tank Sizing Calculator and Tank Sizing Guide to set your real fill volume against the 19,015-pound rated contents weight, and budget your trailer and tie-downs around the loaded figure for your liquid, not the water number. At 70 inches wide, 102 inches long, and 64 inches tall on its frame, also confirm your trailer deck width and overall loaded height against your lane before you commit. For DOT classification on fertilizer and portable utility hauling, our guides on applicator and leg tanks for fertilizer, loaf-style portable utility tanks under 49 CFR, and fertilizer-blend tank stratification walk through the scope and field checks that keep a load legal and on-spec.
