The Enduraplas 1000 Gallon Black Horizontal Sump Bottom Leg Tank with frame is a transport-and-haul vessel built for moving liquid loads, not just storing them. The black polyethylene body holds 1000 gallons, measures 94 inches long by 60 inches wide and stands 71 inches tall on its integrated leg frame, with the sump bottom designed to drain toward the outlet so you can empty the tank cleanly between fills. As a horizontal leg tank, it sits low and stable for skid mounting or trailer haul, and the 1.9 specific gravity rating is what sets this Enduraplas apart from a basic water tank: the wall is engineered for dense liquids, which is why this unit carries chemical and fertilizer hauling duty most 1000 gallon horizontal tanks cannot.
Will it hold what you need to haul?
Match the load to the rating before you fill. Full of water this tank carries roughly 8,340 pounds of contents, and the body is rated to a maximum contents weight of 15,846 pounds. Those two numbers define the wall: 15,846 divided by 8,340 works out to about 1.9, so the rated ceiling is exactly a 1.9 specific gravity fluid filled to the brim. To check your own fluid, multiply its specific gravity by 8,340. DEF at roughly 1.09 specific gravity comes out near 9,090 pounds full, comfortably under the limit; a 1.5 specific gravity fluid lands around 12,510 pounds, still inside it; and you only approach the 15,846 pound ceiling as you near 1.9. Size the trailer, skid, or truck axle to that loaded weight rather than the empty tank, and use the 60 by 94 inch footprint to confirm the deck space the frame needs. Our Tank Sizing Calculator and Tank Sizing Guide walk through the math, and the sizing guide covers how leg tanks differ from upright storage. Note that 1.9 specific gravity is the top of this tank's rating, and we do not list a higher-SG horizontal leg tank as a substitute; if your fluid exceeds the weight limit above, call us before buying rather than over-filling.
Chemical compatibility
Confirm the resin first. Our data lists the wall as HDLPE but flags it with a question mark, so verify whether it is HDLPE or cross-linked (XLPE) at 866-418-1777 before putting any chemical into service. The two resins behave differently against aggressive fluids, and that answer determines whether the harshest rows below, such as sulfuric acid at 98%, hydrochloric acid at 37%, and peracetic acid, are even valid for this tank. This is a 1.9 specific gravity polyethylene tank, and the chemicals below come straight from the OEM chemical-resistance chart, which is concentration and temperature specific, so verify your exact strength and operating temperature for your application.
Compatible services include acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS fittings, EPDM), ethylene glycol at 100% (PVC, EPDM), ferric chloride at 50% (PVC, EPDM), ferric sulfate at 60% (PVC, EPDM), ferrous sulfate at 20% (PVC, EPDM), hydrochloric acid at 37% (PVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), hydrofluosilicic acid at 26% (PP/PVC, Viton), hydrogen peroxide at 50% (PVC, Viton), magnesium chloride at 30% (PVC, EPDM), peracetic acid at 30% (316SS, Aflas), phosphoric acid at 85% (PVC, Viton), potassium carbonate at 50% (PVC, EPDM), potassium hydroxide saturated (PVC, EPDM), sodium carbonate at 30% (PVC, EPDM), sodium hypochlorite below 16.5% (PVC, Viton), sodium thiosulfate at 40% (PVC, EPDM), sulfuric acid at 98% (CPVC, Viton), and urea solution at 50% (PP/PVC, EPDM). A second group is listed without a concentration in our data, which means the strength was not specified rather than that any strength is fine: polyaluminum chloride (PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), and zinc orthophosphate (PP/316SS, EPDM); confirm your operating strength with us for any of these. Ozonated water is rated up to 10 PPM (PVC, EPDM). The fitting and gasket material listed for each fluid matters as much as the tank wall, so spec your outlet hardware to match, and see the full chemical compatibility resource before you commit.
The mistake to avoid
The most common error on a 1000 gallon horizontal leg tank like this is treating the 1.9 specific gravity rating as a green light for any liquid. It is not. A fluid heavier than your math allows pushes you past the 15,846 pound maximum contents ceiling, and the wrong fitting or gasket material will fail long before the polyethylene does, regardless of how chemical-resistant the tank itself is. One more thing to confirm up front: outlet, bulkhead, and sump-drain hardware is not specified in our current data for this tank, so do not assume a fitting kit is included. Confirm the resin (HDLPE versus XLPE), match the concentration to the chart, and confirm fitting size and gasket material for your fluid at 866-418-1777 before you order. For DEF or fertilizer trailer hauling, review our guides on applicator and leg tanks for fertilizer, portable utility tank DOT classification, and fertilizer-blend tank stratification. Check the technical drawing on this page for fitting positions and overall geometry before you order.
