Enduraplas 200 Gallon Black Horizontal Sump Bottom Leg Tank w/ Frame

The Enduraplas 200 Gallon Black Horizontal Sump Bottom Leg Tank ships as a complete unit with its integrated steel frame, built for transport and transfer work where you need the tank to ride low and drain clean. It holds 200 gallons in a black polyethylene body measuring 32 inches high, 47 inches wide, and 55 inches long, sitting on a 47.0 x 55.0 inch footprint. The sump bottom pulls liquid to a low point so you can draw the tank down further than a flat-bottom horizontal, and the frame is designed to be strapped down for haul-and-go duty. This is the 200 gallon horizontal leg tank an applicator or fleet operator reaches for when the load has to travel.

Will this 200 gallon horizontal leg tank handle your load?

The black resin body carries a 1.9 specific gravity rating, a heavy-duty rating that covers dense liquids well beyond the weight of water. A water fill weighs about 1,668 pounds, but that is not the number to mount to: at the 1.9 SG ceiling the contents alone reach 3,169 pounds, nearly double a water fill. Spec your frame straps, trailer, and axle to roughly 3,169 pounds of liquid plus the tank-and-frame tare, not the 1,668-pound figure a buyer instinctively reaches for. Plan the layout around the full 47 x 55 inch footprint. If you are deciding between sizes for a job, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit. See the technical drawing on this page for fitting locations and overall geometry.

Chemical compatibility

This is a polyethylene tank with a 1.9 specific gravity rating, read as HDLPE; confirm HDLPE versus XLPE with us before any chemical service, because that distinction changes what the wall will tolerate. The SG rating means the body is built to carry dense chemistry, but compatibility is set by the chemical, its concentration, and your fitting and gasket materials - not by the tank alone. Based on the OEM chemical-resistance data, which is concentration- and temperature-specific, this tank can be configured for service with strong acids including hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), phosphoric acid (85%), sulfuric acid (98%), and acetic acid (60%); coagulants and salts including aluminum sulfate (50%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), calcium chloride (40%), magnesium chloride (30%), and polyaluminum chloride; caustics and carbonates such as potassium hydroxide (saturated), potassium carbonate (50%), sodium carbonate (30%), sodium bisulfate, sodium bisulfite, and sodium thiosulfate (40%); oxidizers like hydrogen peroxide (50%), peracetic acid (30%), sodium hypochlorite (<16.5%), and ozonated water (up to 10 PPM); and glycols and fluids including ethylene glycol (100%), propylene glycol, DEF (32.5%), urea solution (50%), and zinc orthophosphate.

Match your wetted hardware before you order

The chart resolves to a simple three-bucket gasket rule: Viton on the strong acids and oxidizers (HCl, HF, hydrofluosilicic, phosphoric, sulfuric, hydrogen peroxide, sodium hypochlorite), EPDM on the salts, caustics, glycols, DEF, and urea, and Aflas only on peracetic acid. Three fitting calls deserve their own line because they are the easiest to get wrong by reusing PVC hardware: DEF (32.5%) requires 316 stainless wetted fittings - PVC is not acceptable - and the same 316SS rule applies to peracetic acid, while sulfuric acid (98%) calls for CPVC rather than PVC. Match every fitting and gasket to the chemical-resistance chart at your exact concentration and temperature; verify against the full chemical compatibility data before ordering.

The mistake to avoid on this tank

The common error on a heavy-duty horizontal like this is treating the 1.9 SG rating as permission to skip the wetted-material check. The body may carry the density, but the wrong gasket on the wrong acid is what fails first - EPDM where the chart calls for Viton, or 32.5% DEF run on PVC instead of 316 stainless. Confirm the resin with us, match every fitting and gasket to the chart, and mount to the 3,169-pound loaded weight, not the empty tank.
