The Enduraplas 3200 Gallon White Horizontal Sump Bottom Leg Tank (SKU THD03200W) is a transport-and-store workhorse built for fertilizer, water, and chemical hauling where the load has to ride low and stay put. It holds 3,200 gallons in a natural white polyethylene body measuring 145 in long by 97 in wide by 83 in tall, with a footprint of 97.0 x 145.0 inches. The sump bottom drains toward the outlet so you can pull product down to the last usable inches, and the integrated leg-tank profile cradles the load between supports for stable transport on a trailer or skid. White resin lets you read the liquid level at a glance.
Will it handle your load?
This horizontal leg tank carries a 1.9 specific-gravity rating, so it is engineered for dense liquids well beyond plain water. Plan your fill by weight, not just volume. Filled with water, 3,200 gallons weighs about 26,688 lbs; at the tank's full 1.9 SG rating the maximum rated contents weigh roughly 50,707 lbs. That spread is the whole point of the 1.9 wall: a fertilizer blend, brine, or acid solution heavier than water still falls inside the design envelope, but you must confirm your axle ratings, trailer, and ground support can carry the loaded weight. Outlet, sump, and fitting sizes are not pre-set in this listing - they are confirmed per order against the manufacturer drawing and specifications, so tell us how you plan to plumb it. Run your product's specific gravity and target volume through the Tank Sizing Calculator, and if you are deciding between sizes, the Tank Sizing Guide walks through matching capacity to duty cycle.
Chemical compatibility
The body is polyethylene (resin grade pending OEM confirmation), rated to 1.9 specific gravity. Because the resin designation is unconfirmed, verify HDLPE versus XLPE with us before putting this tank into chemical service - cross-link density drives long-term resistance. Always match concentration and temperature to the OEM chemical-resistance chart, which is concentration- and temperature-specific. Within the 1.9 SG envelope this tank suits a broad chemical range when fittings and gaskets are specified correctly, including acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, 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 (<16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), and zinc orthophosphate (PP/316SS, EPDM). Ozonated water (up to 10 PPM, PVC, EPDM) is also listed but has no dedicated compatibility reference yet, so confirm that one with us by phone before service. Watch the fitting-material call-outs: several chemicals here demand metal or upgraded plastic, not standard PVC - DEF, peracetic acid, and zinc orthophosphate take 316SS, and 98% sulfuric acid takes CPVC. On gaskets, oxidizers like hydrogen peroxide, sodium hypochlorite, and sulfuric acid require Viton and peracetic acid requires Aflas, not EPDM. See the full chemical compatibility resource and confirm every selection against the OEM chart at your service concentration and temperature.
The mistake to avoid
Do not assume the 1.9 SG rating means "fill it to the brim with anything." The number protects the wall, but the legs, trailer, and axles still have to carry up to roughly 50,707 lbs of loaded weight - size your running gear to the heaviest product you will haul, not to water. And do not plumb the tank with one default fitting and gasket set: match the fitting metal and gasket to the specific chemical every time, so DEF gets 316SS rather than PVC and an oxidizer never runs through EPDM. Confirm outlet, sump, and fitting locations and sizes against the manufacturer's drawing and specifications before you plumb it.
