The Enduraplas 2200 Gallon Black Horizontal Sump Bottom Leg Tank with frame is a transport-and-haul tank built to carry full loads of water or heavy-density agricultural and process liquids on a trailer or skid. It holds 2,200 gallons, measures 130 inches long by 71 inches wide by 76 inches tall, and is molded in black polyethylene with a 1.9 specific-gravity rating - meaning the tank wall and integrated leg frame are engineered to support contents up to 1.9 times the weight of water. The sump bottom drains low for cleaner emptying between loads, and the molded leg design seats this horizontal leg tank squarely on a frame or trailer deck.
Will it work for your load?
Start with weight, because on a horizontal leg tank the rated density is the limiting number, not the gallons. Filled with water this tank carries about 18,348 lb of contents; at its 1.9 SG rating it is built for contents up to roughly 34,861 lb. Use those two figures to check your trailer axle ratings and your tow vehicle before you load - a 2,200-gallon haul tank running a heavy fertilizer blend or brine is a very different load than the same tank running water. The 71 x 130 inch footprint tells you the deck space you need. Run your exact liquid and volume through the Tank Sizing Calculator, and if you are matching this tank to a hauling job, the Tank Sizing Guide walks through how density, capacity, and frame support work together. For mobile fertilizer and DOT-classification questions specific to leg and applicator tanks, see our guides on applicator and leg tanks for fertilizer and portable utility tanks under 49 CFR 173.5. Verify fitting locations, sump outlet size, and frame dimensions against the technical drawing on this page.
Chemical compatibility
This tank is molded in polyethylene rated to 1.9 specific gravity, which is what makes it suitable for many heavy and aggressive liquids - but the resin should be confirmed first: verify with us whether this is HDLPE or XLPE before committing the tank to chemical service, because that distinction changes what it can safely hold. The 1.9 SG rating gives you real density headroom for concentrated solutions. Compatible chemicals from our chemical-resistance reference include sulfuric acid (98%, CPVC fittings, Viton gaskets), hydrochloric acid (37%, PVC, Viton), phosphoric acid (85%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), sodium hypochlorite (under 16.5%, PVC, Viton), hydrogen peroxide (50%, PVC, Viton), ferric chloride (50%, PVC, EPDM), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), diesel exhaust fluid (DEF) (32.5%, 316SS fittings, EPDM), urea solution (50%, PP/PVC, EPDM), ethylene glycol (100%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), peracetic acid (30%, 316SS, Aflas), and acetic acid (60%, PP/PVC, EPDM), among others including ferric sulfate, ferrous sulfate, hydrofluosilicic acid, magnesium chloride, polyaluminum chloride, potassium carbonate, propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate, sodium thiosulfate, and zinc orthophosphate. Ozonated water up to 10 PPM is also listed (PVC fittings, EPDM gaskets). As a rule from the chart: oxidizers and strong acids on this tank take Viton gaskets, while salts, glycols, DEF and urea run on EPDM - so match the gasket, not just the fitting. Always confirm against the chart at your actual concentration and temperature, since the listings here are concentration- and temperature-specific. Full details are on our chemical compatibility reference.
The mistake to avoid
Do not size this tank by gallons alone. The number that gets people in trouble on a 2,200-gallon haul tank is density: water fills it to about 18,348 lb, but a heavier-than-water liquid can push contents toward the 1.9 SG ceiling of roughly 34,861 lb - enough to overload axles, exceed trailer ratings, or stress the frame if you don't plan for it. Confirm your liquid's specific gravity, run it against the gasket and fitting materials in the chart, and never put a chemical in service before confirming the tank's resin with us.
