The Enduraplas 1010 Gallon White Horizontal Sump Bottom Leg Tank ships with its own steel frame and a sloped sump bottom, built for haul-and-apply work where the load rides on a trailer or skid and needs to drain clean. At 130 inches long and 49 inches wide with a 59-inch height, this horizontal leg tank holds 1,010 gallons in natural white polyethylene and carries a 1.9 specific gravity rating, which is what makes it a true chemical-service tank rather than a water-only vessel. The sump bottom pulls product to a low point so you empty the tank instead of leaving heel behind every cycle.
Will it work for your load
Run the numbers before you commit. Full of water this horizontal tank weighs about 8,423 lb, and the frame is rated to carry contents up to 16,004 lb, so you have real headroom for heavier liquids up to the 1.9 SG limit. That 16,004 lb rating IS the 1.9-SG-full number, so a lighter product around 1.5 SG rides well under the limit, while water-only is your transport floor at roughly half that weight. Chemical-full nearly doubles the load over water, which means trailer and axle ratings matter as much as the 49.0 x 130.0 inch footprint you check against your deck or pad. Size the actual product weight against the 16,004 lb contents rating, not just the gallon count. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your fill weight, and see the technical drawing on this page for fitting and sump-bottom detail.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. Resin is recorded as HDLPE (unconfirmed) - call 866-418-1777 to confirm the exact grade, HDLPE versus XLPE, before putting it into chemical service. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific, so match your exact conditions against it before ordering.
Tanks at this 1.9 SG rating with the right fittings and gaskets handle a wide range of products, including sodium hypochlorite (under 16.5%, PVC fittings, Viton gaskets), sulfuric acid (98%, CPVC fittings, Viton gaskets), hydrochloric acid (37%, PVC fittings, Viton gaskets), ferric chloride (50%, PVC, EPDM), aluminum sulfate (50%, PVC, EPDM), phosphoric acid (85%, PVC, Viton), hydrogen peroxide (50%, PVC, Viton), calcium chloride (40%, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), ethylene glycol (100%, PVC, EPDM), and DEF (32.5%, 316SS fittings, EPDM gaskets). More aggressive products such as peracetic acid (30%) call for 316SS fittings and Aflas gaskets. The full list on the OEM chart also covers acetic acid, ferric and ferrous sulfate, hydrofluoric and hydrofluosilicic acid, magnesium chloride, polyaluminum chloride, potassium carbonate, propylene glycol, sodium bisulfate, sodium bisulfite, sodium thiosulfate, urea solution, zinc orthophosphate, and ozonated water up to 10 PPM. Confirm fitting and gasket material for your specific chemical on each product page and at /chemical-compatibility/.
The mistake to avoid
The number-one error on a leg tank like this is matching fittings and gaskets to the tank instead of to the chemical. The polyethylene shell tolerates far more than a PVC bulkhead or EPDM gasket will, so the fitting and gasket material listed for your product is the real limit, not the tank wall. Sodium hypochlorite, sulfuric acid, and hydrogen peroxide all need Viton; DEF and peracetic acid need stainless. Get the gasket wrong and you leak before the tank ever fails. Confirm the resin and your concentration with us at 866-418-1777 before you run anything aggressive.
