Norwesco 3725 Gallon Horizontal Leg Tank

Where this tank goes

This is the standard rated version of the 3725 gallon leg body. Buy it when you need one large volume of water or a liquid near the weight of water: a water tank at a yard or a pump station, a nurse tank at a blend site, a fertilizer tank on a flat deck or a skid. Liquids heavier than 1.5 times water need the 3725 gallon blue heavy duty leg tank, which is the same body with a 1.9 rating. The round body on moulded legs sits on a flat pad without a cradle, and at 97 inches tall it fills from a short ladder. Where it rides on a vehicle or a skid, strap it with the 4 bands Norwesco specifies, band part 63284, over the moulded recesses and never over the manway; we put the bands on the same order. Our guide to Norwesco applicator and leg tanks and the DOT non-roadable trailer rules covers how a tank this size is classified on the road, and the farm fleet DOT classification guide covers the agricultural exemption.

What goes in it

Water, liquid fertilizer and the farm and treatment chemicals that polyethylene handles. Check the liquid in our chemical compatibility guide before the first fill; urea solution, DEF, calcium chloride, sodium hypochlorite and sulfuric acid are the entries leg tank buyers ask about most. On a 1.5 rated tank the weight of the liquid matters as much as its chemistry, so check both. Keep the contents under 120 F. For the volume itself, use the tank sizing calculator and the tank sizing guide.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting, factory installed low in the end wall, with a 2 inch reducer so you can run a 3 inch or a 2 inch valve from day one. Support the valve and the first length of hose so the fitting carries liquid, not hardware.
2. Manway. A 16 inch threaded vented manway on top for filling, a float and cleaning.
3. Bands. 4 bands, Norwesco part 63284, when the tank is strapped to a deck or a skid. Order them with the tank.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet and manway positions, the band recesses and the leg layout.

Same body, other colours and ratings

The same tank in black, for stored water in the sun: the 3725 gallon black leg tank. For liquids heavier than water: the 3725 gallon blue heavy duty leg tank and the 3725 gallon black heavy duty leg tank. Smaller: the 1800 gallon white leg tank. Larger: the 5025 gallon black heavy duty leg tank. The colour swatches above the price switch between the versions of this tank.

Shipping and receiving

The tank ships as oversize freight, Norwesco's OVS class, 145 by 92 by 97 inches, from the nearest of Norwesco's plants in Fairfield, Texas, Shawnee, Oklahoma and St. Bonifacius, Minnesota. Norwesco gives the ship weight as 1082 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. Have a forklift or a loader on site to unload it. At the tailgate, check the part number against 44047 on the bill of lading, look along all the legs for transit damage, and fill it with water the first time before it carries anything else.
