The Norwesco 3250 Gallon Horizontal Elliptical Leg Tank (N-44598) is a White polyethylene haul-and-store tank built for bulk liquid transport and stationary holding where a low, stable load profile matters. It carries a 1.5 specific gravity rating, holds 3,250 gallons, and sits on integrated legs across a 88.0 x 152.0 inch footprint, standing 81 inches tall. Plain water at full volume weighs 27,105 lbs, and the tank is rated to carry contents weighing up to 40,658 lbs. That leaves 11,553 lbs of headroom above plain water before you reach the contents rating, which means the tank is genuinely usable to its full 3,250 gallons at its 1.5 SG rating, not capacity-derated. This unit ships without fittings, so you specify and source the bulkhead, outlet, and vent hardware your application needs.
Will it work for your job?
The elliptical leg-tank shape is the workhorse of fertilizer and bulk-liquid hauling: the wide 88-inch belly and 152-inch length keep the load low for over-the-road stability on a nurse trailer or skid, while the 81-inch height stays within reach for top access. With a 1.5 SG rating, this tank handles standard ag liquids and water at full volume, but match contents weight to the rating, not just the gallons. At 3,250 gallons of plain water you are already at 27,105 lbs, and the 40,658 lb contents rating is what governs heavier liquids like blended fertilizer. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your liquid's loaded weight against this rating before you order, and review the technical drawing on this page for leg spacing and port layout. For horizontal leg tank and Norwesco tank context on DOT and trailer use, see our guides on Norwesco applicator and leg tanks for fertilizer and portable utility tank DOT classification.
Chemical compatibility
This is a 1.5 specific-gravity polyethylene tank. The resin is recorded as HDLPE pending confirmation, so confirm HDLPE versus XLPE construction with the OEM chemical-resistance chart before placing it in chemical service. Always verify against that chart, which is concentration- and temperature-specific. Because the tank ships bare, match your fitting and gasket materials to your liquid. At its 1.5 SG rating this tank suits: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets); Aluminum Sulfate (50%, PVC, EPDM); Calcium Chloride (40%, PVC, EPDM); DEF (32.5%, 316SS, EPDM); Ferrous Sulfate (20%, PVC, EPDM); Magnesium Chloride (30%, PVC, EPDM); Sodium Carbonate (30%, PVC, EPDM); Urea Solution (50%, PP/PVC, EPDM); and Ozonated Water (up to 10 PPM, PVC, EPDM). The pattern holds across this group: PVC body with EPDM seals for the salts and sulfates, 316SS with EPDM for DEF, PP/PVC with EPDM for urea and acetic acid.
What needs a heavier-rated tank
Several common ag and water-treatment chemicals exceed the 1.5 SG service window of this tank and require a 1.9 specific-gravity tank instead, and within that group the seal material, not just the SG, is the failure point. The EPDM-compatible group runs with standard EPDM seals on a 1.9 SG tank: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Thiosulfate, and Zinc Orthophosphate. The oxidizers and strong acids demand Viton or Aflas seals: Hydrochloric Acid (Viton), Hydrofluoric Acid (Viton), Hydrofluosilicic Acid (Viton), Hydrogen Peroxide (Viton), Phosphoric Acid (Viton), Sulfuric Acid (CPVC, Viton), Sodium Hypochlorite (Viton), and Peracetic Acid (316SS, Aflas). For any of these, call 866-418-1777 to spec a 1.9 SG Norwesco horizontal leg tank rather than running this one out of spec. When you are blending liquids in a tank this size, our guides on fertilizer-blend tank stratification and pump-around recirculation loop engineering cover the mixing and density discipline that keeps a blend on-spec. See the full chemical compatibility reference before committing.
