The Enduraplas 3200 Gallon Black Horizontal Sump Bottom Leg Tank ships as a complete unit on its steel frame, built for haul-and-transfer duty where you need to move heavy liquid loads over the road. Rated to a 1.9 specific gravity, this polyethylene horizontal leg tank measures 145 inches long (about 12 feet of travel length), 97 inches wide (about 8 feet across, which trips over-width rules for many transport permits), and 84 inches tall. The integrated frame keeps the center of gravity low for transport, and the black resin shields the contents from UV and light. If you are deciding whether this size fits your trailer, skid, or pad, run the dimensions on this page through our Tank Sizing Calculator.
Will it work for your load?
This is a 3200-gallon horizontal leg tank with a 1.9 specific-gravity rating, which is what makes it suited to dense fluids rather than just water. Filled with plain water it holds roughly 26,688 pounds of contents; the SG 1.9 rating gives you headroom up to about 50,707 pounds of rated contents weight before you reach the resin's design limit. That spread matters: a fluid heavier than water eats into your capacity, so plan the fill level around the actual density of what you are hauling, not just the gallon mark. The black UV-shielding resin and the haul-ready frame make this a natural fit for transferring DEF or urea solution in the field, provided you spec the right fittings (DEF calls for 316SS fittings and EPDM gaskets per the chemical data). Size your trailer, hitch, and tie-downs for a fully loaded weight in the 25,000-plus pound range, and use our Tank Sizing Guide when matching this tank to a vehicle or a fixed pad.
Chemical compatibility
This tank carries a 1.9 specific-gravity rating. Confirm the exact resin (HDLPE versus cross-linked XLPE) with us before putting it into chemical service, because the two resins behave differently against oxidizers and solvents. The following chemicals are documented as compatible with this tank's SG rating per the chemical-resistance data, which is concentration- and temperature-specific; verify your exact concentration and operating temperature against that data before committing. As a working rule from that data: salts, glycols, and bases run on EPDM gaskets; strong acids and oxidizers (HCl, hydrogen peroxide, hypochlorite, phosphoric, sulfuric) call for Viton; peracetic acid needs Aflas; and DEF and peracetic acid require 316SS fittings.
Compatible chemicals include 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 (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). Match the fitting and gasket material to the chemical you run, and see our full chemical compatibility reference before you order.
The mistake to avoid
The most common error on a horizontal leg tank like this is treating the 3200-gallon mark as a fixed weight ceiling. It is not. At SG 1.9 the rated contents weight is over 50,000 pounds, so a high-density fluid filled to the brim can overload the frame, the trailer, and the bridge laws long before the tank itself complains. Pair that with the resin caveat: do not assume oxidizer service such as concentrated hydrochloric acid, hydrogen peroxide, or hypochlorite is safe until the resin question is settled and the fitting and gasket materials above are matched to your concentration. The name calls this a sump bottom tank, so confirm the actual outlet and bulkhead size with us before you plumb it.
