The Norwesco 3250 Gallon Horizontal Elliptical Leg Tank in black is built for transport. Its low-slung elliptical body sits on integrated legs so the tank rides flat on a skid, trailer, or service bed, and the black polyethylene wall blocks light to slow algae growth in the liquid you haul. At a 1.5 specific gravity rating, this tank is engineered to carry contents up to 1.5 times the weight of water, which is what makes it a workhorse for fertilizer, brine, and ag chemical runs rather than a plain water barrel.
Will it work for your load?
Capacity is 3250 gallons in an elliptical leg-tank footprint of 88.0 x 152.0 inches, standing 82 inches tall. Plan your trailer or pad around those numbers, and confirm the technical drawing on this page for leg spacing before you build a frame. Fitting and outlet configuration is not specified in this listing, so check the drawing or call before you plumb the tank. The weight math matters more than the dimensions here: filled with water this tank carries about 27,105 lb, and at its full 1.5 SG rating the contents alone can reach roughly 40,658 lb. That is a serious axle and frame load, so size your trailer, suspension, and tie-downs to the heavier rated figure, not the water number. If you are matching a tank to a haul weight or trailer rating, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide. For how leg and applicator tanks fit DOT and trailer-scope rules, the guides on Norwesco applicator and leg tanks for fertilizer and portable utility tanks under the 49 CFR ag exemption are worth reading first.
Chemical compatibility
This is a 1.5 SG polyethylene tank. The resin is recorded as HDLPE, but confirm whether the wall is HDLPE or XLPE before putting it into chemical service, since cross-link affects what it can hold. Against the OEM chemical-resistance chart, which is concentration and temperature specific, this tank handles acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), ferrous sulfate at 20% (PVC, EPDM), magnesium chloride at 30% (PVC, EPDM), sodium carbonate at 30% (PVC, EPDM), urea solution at 50% (PP/PVC, EPDM), and ozonated water up to 10 PPM (PVC, EPDM). Because this listing carries no fittings, match fitting and gasket material to your chemical exactly as listed and confirm each selection against the OEM chart at its rated concentration and temperature before filling; call 866-418-1777 and we will confirm the fitting and gasket build for your chemical.
The mistake to avoid: under-rating the tank
The most common error on this class of tank is reaching for it on a denser fluid than 1.5 SG allows. Several common ag and water-treatment chemicals require a heavier 1.9 SG tank, not this one: ethylene glycol, ferric chloride, ferric sulfate, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, peracetic acid, phosphoric acid, polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium hypochlorite, sodium thiosulfate, sulfuric acid, and zinc orthophosphate. If your product is on that list, step up to a 1.9 SG tank, and note that the heavier tank can also change the gasket spec: several of these acids (hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sodium hypochlorite, sulfuric) call for Viton rather than EPDM, and peracetic acid needs Aflas. Ask us for the 1.9 SG equivalent in this size when you call. When you blend fertilizer in a tank like this, watch for density-driven stratification; the field methods in our guide on fertilizer-blend tank stratification catch a layered tank before the spreader runs off-spec. Confirm your chemical and concentration on its page above and on the master chemical compatibility reference.
This tank ships LTL, freight quoted live to your ZIP from the nearest Norwesco plant in St. Bonifacius, MN, Lancaster, OH, or Fairfield, TX. At roughly 40,658 lb rated, which of those plants is closest to you materially changes the LTL number, so get a freight figure in minutes with our Freight Cost Estimator, or call 866-418-1777 and we will quote the haul and confirm the right fittings and SG rating for your chemical before you order.
