The Enduraplas 800 Gallon White Horizontal Sump Bottom Leg Tank ships as a complete unit on its molded frame, ready to mount to a sprayer skid, nurse trailer, or shuttle deck. The poly tank holds 800 gallons in a 94-inch-long body that stands 56 inches tall and 60 inches wide, and the sump-bottom floor pitches contents toward the outlet so you can draw down close to empty without rocking the trailer. It carries a 1.9 specific gravity rating, the heavy-duty density tier - this is the reason this Enduraplas horizontal leg tank handles dense liquid fertilizer and chemistry, not just water. The resin is recorded as HDLPE but is unconfirmed; because crosslinked and linear poly behave very differently with aggressive products, confirm HDLPE versus XLPE with us before you commit it to chemical service.
Will it work for your liquid and your trailer?
Plan the load by weight, not by gallons. Full of water, the tank and contents run about 6,672 pounds; at its maximum rated contents weight the tank is built to carry up to 12,677 pounds, which is what the 1.9 SG rating buys you - roughly 1.9 times water density before you reach the tank's limit. Use those numbers against your trailer's axle and tongue capacity before you fill, because a horizontal leg tank rides directly on its frame and the deck and tie-downs have to take the full loaded weight. The 60.0 x 94.0 inch footprint tells you the deck space you need. If you are matching this tank to a job, the Tank Sizing Calculator and Tank Sizing Guide walk you through capacity versus weight, our writeups on applicator and leg tanks for fertilizer and portable utility tanks and the 49 CFR 173.5 farm exemption cover the DOT classification questions on transport leg tanks, and the fertilizer-blend tank stratification guide is worth a read if you are blending and hauling dense fertilizer. See the technical drawing on this page for sump detail and fitting locations; outlet, fill, and vent sizes are not in our records, so confirm them with us before ordering.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity, which is what makes it a candidate for chemical and fertilizer service rather than water alone. Because the resin is recorded as HDLPE but unconfirmed, confirm HDLPE versus XLPE before chemical service - that single answer gates which of the products below are actually safe. The chemicals listed are workable per the OEM chemical-resistance chart at the listed concentrations and with the listed fitting and gasket materials; that chart is concentration- and temperature-specific, so verify your exact strength and operating temperature before ordering.
Workable products include acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50%, calcium chloride at 40%, DEF at 32.5% (316SS fittings, EPDM), ethylene glycol at 100%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, hydrochloric acid at 37% (PVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), hydrofluosilicic acid at 26%, hydrogen peroxide at 50% (PVC, Viton), magnesium chloride at 30%, peracetic acid at 30% (316SS fittings, Aflas gaskets), phosphoric acid at 85%, polyaluminum chloride (PVC, EPDM), potassium carbonate at 50%, potassium hydroxide saturated, propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate at 30%, sodium hypochlorite below 16.5% (PVC, Viton), sodium thiosulfate at 40%, sulfuric acid at 98% (CPVC, Viton), urea solution at 50% (PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water up to 10 PPM (PVC, EPDM). For the full picture and gasket and fitting selection, see our chemical compatibility reference.
The mistake to avoid
The single biggest error on a tank like this is matching fittings and gaskets to the wrong product. Look at the list above: hydrochloric acid, hydrofluoric acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, and sulfuric acid all call for Viton gaskets, sulfuric acid needs CPVC, and peracetic acid needs Aflas - drop in the EPDM hardware that ships fine for fertilizer salts and an oxidizer or strong acid will chew it up. Confirm the resin type, your exact concentration, and the matching fitting and gasket material for your specific liquid before you put this tank into service.
