Norwesco 2635 Gallon HDPE Horizontal Elliptical Leg Tank in Black

On a nurse trailer or a flatbed

At 140 by 90 inches the tank fills the deck of a nurse trailer or a flatbed, and the elliptical section keeps 72 inches of height from becoming a tall load. Full of water the contents alone weigh close to 22000 lb, and heavier with fertilizer, so the trailer's axle and tire ratings and the tow vehicle set the limit, not the tank. Strap it through the moulded leg recesses, never over the manway, and use the bands Norwesco makes for this tank wherever it rides on a vehicle; the add-ons box on this page lists them. On the ground it needs a flat, continuous surface under all the legs. Our guide to Norwesco applicator and leg tanks for fertilizer 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

Liquid fertilizer is the usual load for a heavy duty elliptical, with water and the farm and treatment chemicals that polyethylene handles behind it. Before anything new goes in, check the liquid in our chemical compatibility guide; the entries for urea solution, calcium chloride, magnesium chloride, phosphoric acid and sodium hypochlorite are the ones buyers of this tank ask about most. If you want to know why the black tank behaves differently from the white one in the sun, our note on tank colour and pigment chemistry explains it. For the volume itself, use the tank sizing calculator and tank sizing guide.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer, factory installed. Run 3 inch plumbing off it for a fast transfer pump, or leave the reducer in and run 2 inch. Support the valve and the first length of hose so the fitting carries liquid, not hardware.
2. Inlet. None is fitted. Fill through the manway, or tell us where you want a fill port before the order ships.
3. Manway. A 16 inch threaded vented manway on top: wide enough to fill from a hose or a pump, to drop a float in, and to get a hand and a brush inside to clean.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the exact outlet and manway positions and the leg layout for strap planning.

Shipping and receiving

The tank ships LTL from the nearest of Norwesco's plants in Fairfield, Texas; Griffin, Georgia; Hanford, California; Lancaster, Ohio; Shawnee, Oklahoma; St. Bonifacius, Minnesota; or Tooele, Utah. It travels at its own size, 140 by 90 by 72 inches and 952 lb, so plan on a flatbed delivery and a forklift or loader at your end rather than a liftgate. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. Bands ordered with the tank travel with it. At the tailgate, check the part number against 41294 on the bill of lading, look at all the legs for transit damage, and fill it with water the first time before it carries anything else.
