40 Gallon Vertical Liquid Storage Tank

Forty gallons where only a drum would fit

An 18 inch circle is a drum's footprint, and 42 inches of height turns it into 40 gallons. That is the trade this tank makes: it stands in a narrow strip beside a machine, in the gap between a pump skid and a wall, at the end of a greenhouse row or behind the cab on a flat deck, and it goes through a door upright. The duty is a day tank on a chemical feed pump, a batch mixing vessel, make-up water at a wash station, or a working reserve beside equipment. Three things follow from the height. The lid is 42 inches up, fine to reach and awkward to pour into, so the fill wants a line rather than a hose held overhead. The tank is easy to tip at 19 lb empty and lands 500 lb on an 18 inch circle when full, so strap it to a wall, rack or frame before the first fill. And the surface has to carry the whole floor of the tank: a solid deck, not two rails; a slab with no hollow; set level, with nothing packed under one edge. Our complete buyers guide to this 40 gallon tank goes through the placement in detail. Before anything but water goes in, check the liquid in our chemical compatibility guide. Run 40 gallons against your real draw and refill interval in the tank sizing calculator, and take the reserve and freeboard advice from the tank sizing guide.

Openings and fittings

1. Outlet. A 3/4 inch polypropylene female NPT bulkhead fitting low in the wall. A ball valve or a pump suction threads straight into it; support the valve so the fitting carries liquid, not hardware.
2. Lid. An 8 inch threaded vented lid on top, wide enough to fill from a hose and to get a hand inside to clean. The vent lets air move as the level changes; never seal it.
3. Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page and shows the outlet position.

Shipping

This tank ships by UPS from Norwesco's Sheldon, Iowa plant, boxed on its side at 42 by 18 by 18 inches and 17 lb on the label. The listed price is before freight; the freight cost estimator gives the cost to your ZIP, or request a written quote if the job needs paperwork. Check the part number against 44848 on the carton, and fill it with water the first time before it carries anything else.
