Norwesco 1800 Gallon Horizontal Leg Tank with Sump Bottom

The Norwesco 1800 Gallon Horizontal Leg Tank with Sump Bottom (SKU N-42992) is a white polyethylene haul tank built for over-the-road agricultural transport. Molded legs cradle the tank in a frame or skid, and the sump bottom pulls product down to a single low drain point for clean offloading. It holds 1,800 gallons, measures 146 inches long by 62 inches wide and 72 inches tall, and carries a 1.5 specific gravity rating, meaning the resin and wall thickness are engineered to safely haul liquids up to 1.5 times the weight of water.

Will it work for your load?

Sizing is the first thing to get right on a horizontal leg tank. Filled with water, this tank weighs about 15,012 lb; at its maximum rated 1.5 SG contents it reaches roughly 22,518 lb. The 15,012 lb figure is the full-water load and the 22,518 lb figure is the maximum at the 1.5 SG rating; your trailer, axles, and tie-downs have to carry the heavier number plus the tank's own weight, so spec your rig against 22,518 lb, not the water figure. The footprint runs 62.0 x 146.0 inches, so confirm that fits your trailer deck or saddle frame. The technical drawing on this page confirms a molded sump bottom; that sump is the single low drain point that lets the tank drain nearly dry, which matters when you are running fertilizer or any product you do not want stratifying or leaving residue. Confirm the sump outlet size and fitting connection against the drawing before ordering, and use our Tank Sizing Calculator and Tank Sizing Guide to match the weight to your equipment before you commit. This tank ships LTL from Lancaster, OH, so gut-check the distance to your ZIP while you are doing the rig math.

Chemical compatibility

This is a polyethylene tank rated to 1.5 specific gravity. At that 1.5 SG rating it suits the products below at the listed concentrations and fitting/gasket pairings. Confirm the fitting material (PP, PVC, or 316SS as listed) and the EPDM gasket against your exact chemical, concentration, and operating temperature before any chemical service:

• Acetic Acid at 60% - PP/PVC fittings, EPDM gaskets
• Aluminum Sulfate at 50% - PVC fittings, EPDM gaskets
• Calcium Chloride at 40% - PVC fittings, EPDM gaskets
• DEF (diesel exhaust fluid) at 32.5% - 316SS fittings, EPDM gaskets
• Ferrous Sulfate at 20% - PVC fittings, EPDM gaskets
• Magnesium Chloride at 30% - PVC fittings, EPDM gaskets
• Sodium Carbonate at 30% - PVC fittings, EPDM gaskets
• Urea Solution at 50% - PP/PVC fittings, EPDM gaskets
• Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets

See our full chemical compatibility reference, which is concentration- and temperature-specific, before filling.

The mistake to avoid: SG rating

The most common spec error on a 1.5 SG tank is loading a heavier chemical it is not rated to hold. Several products require a higher 1.9 SG tank instead of this one, including 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. Several of these also require Viton or Aflas gaskets rather than EPDM, so stepping up to a 1.9 SG tank means re-spec'ing the gasket, not just the shell. If your product is on that list, step up to a 1.9 SG tank rather than forcing it into this one. If you are blending fertilizer to haul and spread, our guides on Norwesco applicator and leg tanks for fertilizer and fertilizer-blend tank stratification are worth reading before you load.
