Enduraplas 150 Gallon White Horizontal Sump Bottom Leg Tank w/ Frame

The Enduraplas 150 Gallon White Horizontal Sump Bottom Leg Tank arrives as a frame-mounted horizontal leg tank built to ride on a truck deck or applicator skid and run heavier-than-water chemistry. Molded in Natural White polyethylene with a 1.9 specific gravity rating, this 150-gallon unit measures 34 inches high, 41 inches wide, and 46 inches long, sitting on a 41.0 x 46.0 inch footprint. The white tank wall lets you eyeball fluid level at a glance, and the sump bottom drains the tank low so you are not leaving product behind at the end of a run.

Will it work for your job

The 1.9 SG rating is the number that matters here: it means the tank wall is built to carry contents up to 1.9 times the density of water, so dense ag chemicals and heavy fertilizer blends stay within the tank's structural design. Filled with water this 150-gallon tank carries about 1,251 pounds; loaded to its full 1.9 SG rating it is engineered to hold up to roughly 2,377 pounds of contents. That is about 1,126 pounds of additional load you must engineer into the mounting frame, trailer, and truck rating over a plain water fill. Plan around the heavier number, not the water weight, and confirm fluid level against the white sidewall as you fill. If you are matching tank size to a target batch volume or pump rate, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. For mounting and DOT scope on horizontal leg and applicator tanks used in farm-fleet service, the guide on applicator and leg tanks for fertilizer walks through non-roadable-trailer classification, and the portable utility tank 49 CFR 173.5 piece covers the agricultural exemption. See the technical drawing on this page for fitting and outlet locations.

Chemical compatibility

This tank is polyethylene rated at 1.9 specific gravity. The resin is recorded as HDLPE with a question mark in our data, so before any chemical service confirm whether your unit is HDLPE or XLPE (cross-linked), because cross-linked polyethylene resists a different range of aggressive chemistry. The chemicals below are compatible with a 1.9-SG polyethylene tank per OEM chemical-resistance data, but compatibility is concentration- and temperature-specific, so verify your exact conditions against the manufacturer's chemical-resistance chart before committing product. Watch the hardware, not just the tank wall: most chemistry here mates to PVC fittings, but DEF and peracetic acid call for 316 stainless and 98% sulfuric acid requires CPVC, so match the fitting metallurgy. Most rows run EPDM or Viton gaskets; peracetic acid is the one exception, requiring Aflas.

The mistake to avoid

The most common error on a 1.9-SG horizontal leg tank like this one is treating it as a generic water tank. Sizing your trailer or mounting frame to the 1,251-pound full-water number instead of the roughly 2,377-pound rated-contents weight will overload your rig when you run a dense fertilizer or heavy chemical blend. Size the support to the heavier figure, match every fitting and gasket to the chemical in the table above, and resolve the HDLPE-versus-XLPE resin question before you ever introduce product. Stratification is its own trap with blended fertilizers in a horizontal tank; the guide on fertilizer-blend tank stratification covers the mixing protocol that keeps a load from salting out before it reaches the spreader.
