The Enduraplas 3200 Gallon Green Horizontal Sump Bottom Leg Tank (SKU THD03200G) is a polyethylene horizontal leg tank built for hauling and transferring heavy agricultural and industrial liquids on a trailer or skid. It measures 145 inches long, 97 inches wide, and 83 inches tall, with a 97.0 x 145.0 inch footprint. At 83 inches (6 ft 11 in) tall on its molded-in legs, confirm loaded height against your trailer deck height for road clearance. The legs and sump bottom let the tank sit stable on a flat deck and drain low for clean-out. The green polyethylene body carries a 1.9 specific gravity rating, which is what makes this tank suitable for dense fertilizer blends and chemical solutions rather than water alone.
Will it work for your load?
Full of water, this tank weighs about 26,688 pounds, and its maximum rated contents weight is 50,707 pounds. That spread between water weight and rated capacity is the whole point of the 1.9 SG rating: you can fill it with liquids substantially heavier than water, up to that 50,707-pound contents ceiling, without exceeding what the tank is built to carry. Before you spec a trailer, run those numbers against your axle and frame ratings with the Tank Sizing Calculator and the Tank Sizing Guide so the loaded weight matches your equipment. Fitting configuration is not specified in our data for this unit, so confirm the sump-drain outlet size and any fill or vent fittings with us before ordering, since the chemical-specific fitting and gasket pairings below assume you are sourcing fittings to match your service. If you are running fertilizer blends, the fertilizer-blend stratification guide covers how density-driven layering can leave your spreader running off-spec, and the applicator and leg-tank guide walks through DOT scope for fertilizer transport.
Chemical compatibility
This tank carries a 1.9 specific gravity rating, and at 1.9 SG it is already the heaviest-duty rating in this family, so there is no higher-SG step-up needed for the dense fertilizer and chemical blends listed here. The resin designation is not confirmed in our data, so confirm whether this is HDLPE or XLPE with us before putting this tank into chemical service. All pairings on file are concentration- and ambient-temperature specific, and the oxidizers and strong acids degrade polyethylene faster at elevated temperature, so verify the chemical page for your exact concentration and service temperature before loading. Per the chemical-resistance data we have on file, this tank pairs with chemistries including acetic acid at 60%, aluminum sulfate at 50%, calcium chloride at 40%, DEF at 32.5% with 316SS fittings, ethylene glycol at 100%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, hydrochloric acid at 37%, hydrofluoric acid at 48%, hydrofluosilicic acid at 26%, hydrogen peroxide at 50%, magnesium chloride at 30%, peracetic acid at 30% with 316SS fittings and Aflas gaskets, phosphoric acid at 85%, polyaluminum chloride, potassium carbonate at 50%, saturated potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate at 30%, sodium hypochlorite under 16.5%, sodium thiosulfate at 40%, sulfuric acid at 98% with CPVC fittings, urea solution at 50%, zinc orthophosphate, and ozonated water up to 10 PPM.
Fitting and gasket material is chemical-specific, not one-size-fits-all. Most of these chemistries call for PVC fittings with EPDM gaskets, but the oxidizers and stronger acids change that: hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, and sodium hypochlorite want Viton gaskets; sulfuric acid at 98% wants CPVC; DEF and peracetic acid call for 316SS fittings, with Aflas gaskets on peracetic acid; and propylene glycol and zinc orthophosphate use PP. The mistake to avoid is reusing the same EPDM-and-PVC fitting kit across an acid you swapped in. Match the fitting and gasket to the exact chemical and concentration on the chart, and check your specific page for sulfuric acid, sodium hypochlorite, hydrochloric acid, DEF, peracetic acid, phosphoric acid, or ferric chloride, alongside the full chemical compatibility chart, before ordering. Always read the OEM chemical-resistance chart concentration- and temperature-specific.
Freight
This tank ships LTL freight from Neche, North Dakota, quoted live to your ZIP code. At over 13 feet long and nearly 7 tons of rated contents, this is a heavy oversize unit, so freight is best confirmed before you commit. See the technical drawing on this page for dimensional detail, then get a real number with the Freight Cost Estimator or call us at 866-418-1777 to lock in the rate and coordinate delivery to your site.
