The Enduraplas 1400 Gallon Yellow Horizontal Sump Bottom Leg Tank is a polyethylene horizontal leg tank built for haul-and-apply duty, rated to a 1.9 specific gravity so it carries heavy ag fertilizers and dense chemistries that would overstress a standard 1.0-rated tank. It measures 102 inches long by 70 inches wide by 71 inches tall, rides on an integrated frame, and drains through a sump bottom that lets you pull product down to the last usable gallons. It is a natural fit for DEF (diesel exhaust fluid) haul-and-dispense and similar yellow ag and fleet duty.
Will it work for your application?
At full water capacity the tank and contents reach about 11,676 lb, and at its maximum rated 1.9-SG load it carries up to 22,184 lb of product - the 1.9 rating is exactly why that max product weight is about 1.9x the full-water figure. Size your trailer, frame, and tie-downs to the 22,184 lb number, not the water number, when you plan to haul dense liquid. The 70.0 x 102.0 inch footprint defines the deck space you need on a transport skid or trailer. The molded leg-tank geometry keeps the center of gravity low for road and field use; for help matching tank volume to your batch and payload, use the Tank Sizing Calculator and the Tank Sizing Guide. Fitting locations and the sump detail are documented on the technical drawing on this page - review it before you plumb the tank.
Chemical compatibility
This tank is molded from polyethylene and is rated to a 1.9 specific gravity. The exact resin grade is not confirmed in our data, so confirm the construction with us - confirm HDLPE vs XLPE - before committing the tank to chemical service, since it can change which chemistries are appropriate. The chemicals below are drawn from the chemical-resistance data and are concentration- and temperature-specific; always verify against the chart for your exact service conditions and operating temperature.
Compatible chemistries at this tank's 1.9-SG rating include 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), 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 both fitting material and gasket material to your chemical: gasket elastomer varies (several acids need Viton, peracetic acid needs Aflas, not EPDM), and fitting material varies too - DEF and peracetic acid call for 316 stainless, and 98% sulfuric acid needs CPVC rather than plain PVC, so do not bulkhead a stainless-required service in PVC. Full details live on our chemical compatibility resource.
The mistake to avoid
The costly error on a 1.9-SG tank is plumbing it with the wrong material. Sodium hypochlorite, sulfuric acid, phosphoric acid, the hydrofluoric family, and hydrogen peroxide all require Viton (peracetic acid needs Aflas) - run EPDM on those and the gasket fails; likewise DEF and peracetic acid need 316SS and 98% sulfuric needs CPVC, so don't default everything to PVC. Just as important, do not size your hauling rig off the water weight: a horizontal leg tank loaded with dense product can reach 22,184 lb, and overloading the frame or trailer is the failure that ends a season. Confirm the tank construction with us before any aggressive chemical goes in.
