The Enduraplas 2200 Gallon Yellow Horizontal Sump Bottom Leg Tank ships with its own steel support frame and is built for hauling and field-applying heavy liquids that water-rated tanks cannot carry. With a 1.9 specific gravity rating, this horizontal leg tank handles dense agricultural and industrial fluids at full volume - the kind of liquid weight that overruns a standard 1.0 or 1.5 SG tank. The yellow polyethylene body sits low in its frame on a sump bottom that drains toward the outlet, so you empty the tank without leaving product pooled in the floor.
Will it work for your application?
This is a 2,200-gallon horizontal leg tank measuring 130 inches long, 71 inches wide, and 76 inches tall, with a 71.0 x 130.0 inch footprint. Filled with water it carries about 18,348 pounds, and at its full 1.9 SG rating it is engineered for up to 34,861 pounds of contents - run the Tank Sizing Calculator against your liquid's specific gravity before you load it so you stay inside that rating. One caution before you fill: confirm the resin grade before loading any liquid above 1.5 SG, not just before chemical service, since the structural rating depends on it. If you are deciding between sizes or trailer setups, the Tank Sizing Guide walks through how horizontal and sump-bottom configurations move differently on the road than a vertical tank. The integrated frame is what makes this a haul-and-apply unit rather than a stationary storage tank, and the draining sump bottom suits it to mobile service for liquids like DEF, where the 316SS-fitting requirement applies.
Chemical compatibility
This tank is polyethylene with a 1.9 specific gravity rating. The resin grade reads as HDLPE but is not yet confirmed - verify HDLPE versus XLPE with us before committing the tank to any chemical service, since crosslinked and linear polyethylene behave differently with aggressive oxidizers and acids. Per the published chemical-resistance data (always concentration- and temperature-specific), this tank is rated for liquids including Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Phosphoric Acid (85%, PVC, Viton), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sulfuric Acid (98%, CPVC fittings, Viton gaskets), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM), among others on the full chart including Ferric Sulfate, Ferrous Sulfate, Hydrofluoric Acid, Hydrogen Peroxide, Peracetic Acid, Potassium Hydroxide and the sodium and potassium salts. Seal material is a real ordering decision here: most salts and glycols run on EPDM, the aggressive acids and oxidizers - hydrochloric, phosphoric, sulfuric, hydrogen peroxide, hydrofluoric and sodium hypochlorite - call for Viton, and peracetic acid (30%) is the single chemical on this chart that requires Aflas seals. Fittings split too - DEF and peracetic acid both need 316SS rather than PVC. A 98% sulfuric acid load is the clearest case for why the 1.9 rating exists: it is both chemically aggressive and physically heavy, exactly the pairing this tank's CPVC-and-Viton seal spec and high SG rating are built for. See the full chemical compatibility reference before you order fittings.
The mistake to avoid
The single most common error on a tank like this is loading a dense liquid into a tank that is not SG-rated for it. This unit's 1.9 rating is the reason it can haul heavy fertilizer blends, brines and concentrated solutions - but stratification still bites operators who blend and then let a tank sit. Read our guide on fertilizer-blend tank stratification so a density-layered load does not run your spreader off-spec. For DOT scope and trailer-classification questions on leg and applicator tanks, the applicator and leg tank guide and the portable utility tank classification guide explain where the agricultural exemption applies.
