The Norwesco 1035 Gallon HDPE Horizontal Elliptical Leg Tank ships with Norwesco's standard fitting package and is built for the working life of a sprayer trailer, nurse rig, or field-transport skid. The elliptical leg-tank profile sits low and self-supporting on its molded legs, so the load rides stable on a trailer instead of perched up high. It holds 1035 gallons in High Density Linear Polyethylene, carries a 1.5 specific gravity rating, and measures 54 inches high by 79 inches wide by 89 inches long on a 79.0 x 89.0 inch footprint. The blue body shades the contents and lets you eyeball the liquid level through the wall.
Will it handle your load
This is a haul tank, so weight is the number that decides the job. Filled with water at 1.0 specific gravity, the tank and contents reach about 8,632 pounds. At the full 1.5 specific gravity rating it is engineered to carry up to 12,948 pounds of contents. That step from water to a full 1.5-SG product adds roughly 4,316 pounds, and that delta is what decides your trailer, axle, and tow-vehicle rating. Size to the heavier of those two figures for the product you actually haul, not to water alone. The Tank Sizing Calculator and Tank Sizing Guide help you match this horizontal leg tank to your gallons-per-acre and refill cadence before you commit. Check the technical drawing on this page for outlet size and placement before you plumb the manifold.
Chemical compatibility
The tank shell is HDLPE rated to 1.5 specific gravity. At that rating it suits a range of ag and water-treatment liquids when you match the fitting and gasket materials to the chemical. Confirm chemical resistance against Norwesco's chemical-resistance chart for your exact concentration and temperature before filling, and pick fittings and gaskets accordingly:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
The mistake to avoid on this tank is the specific gravity ceiling. This is a 1.5 SG shell, and several common treatment chemicals are heavy enough to need a 1.9 specific gravity tank instead - among them 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. These are not just heavier: Hydrochloric Acid, Sodium Hypochlorite, Sulfuric Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, and the hydrofluorics also call for Viton or Aflas gaskets and CPVC or 316SS fittings rather than the EPDM/PVC used elsewhere. If your product is on that list, step up to the higher-SG tank rather than risk this one, and see the chemical compatibility tool for the full picture.
