Norwesco 3725 Gallon Black Horizontal Leg Tank

Same 145 by 92 by 97 inch shell, different part number

Take the top of that table seriously before reading anything else on this page, because four part numbers share one set of dimensions and a buyer who orders on gallons alone will get whichever one the paperwork happens to land on. This row and the 44049B row are the same 3725 gallons in the same 145 by 92 by 97 inch shell, and the sheet separates them by the words in the names, by two empty weights that are printed as 1320 lb here and 1450 lb there, by two grade lines, by two outlet cells and by two warranty terms. Six cells, printed by the maker, no arithmetic between them and no explanation offered by us for what the name words mean.

The spine of this particular page is that 44047B is the row whose warranty cell reads 3 Year Warranty, whose grade line reads 1.5, whose outlet cell names a bulkhead fitting with no reducer beside it, and whose empty weight cell is the lighter of the two printed figures. If your product is water or something around the mass of water, every one of those cells is doing its job on this row. If your purchasing spec names a mass per gallon well above water, open 44049B and read its cells instead; that is a comparison of two printed sheets, not a judgement of either tank.

The two lower rows are neighbours rather than alternatives. N-42990 holds 1800 gallons in a 62 inch width, and 42602 holds 5025 gallons in this same 92 inch width stretched to 190 inches long.

Who takes the 44047B row and why

The duty on this record is written in one cell: a grade line of 1.5 with a maximum contents figure of 46600 lb. The product application cell is blank, so the sheet names no service, no industry and no product. The buyer is therefore anyone whose stored liquid sits inside that printed figure and who needs a large, fixed, low-slung body they can fill from the top and pump out of the bottom day after day at the same spot.

In practice that is a yard, a pad beside a shed, a fill point at the end of a run of pipe. Twelve feet of length and close to eight feet of width is a lot of ground, but only 97 inches of height, which is the trade a horizontal body makes: it takes the footprint and gives you back the headroom. If the building you are putting it in has a low door, a low eave or a beam across the middle of the bay, this shape is the reason you are looking at a leg tank rather than a vertical of the same volume.

The honest limitation to flag on this one is the inlet cell, which is empty. One port is named on this record and it is the outlet; nothing on the sheet describes a top fill connection, a fill line size or a thread for one. Do not plan a piped fill from this listing. The install specific that follows from it: decide now whether you are filling through the 16 inch manway with a wand or hose, because if the answer is anything else it is a question for the factory and it is a much cheaper question before the order than after. Our tank sizing guide is worth a read if the volume itself is still being argued about, and the sizing calculator will turn a daily figure into gallons.

The outlet cell, read straight

That table is the complete plumbing content of the record, and the top line is the one your pump conversation starts from. A 3 inch female NPT bulkhead in the shell is a large draw-off for a tank this size, and it sets the ceiling on how fast you can move product out: whatever suction line you run, the tank end of it is the size the cell prints and nothing on this sheet offers a second port, a second size or an adapter. The heavy duty part number in the family table above prints an outlet cell that adds a reducer; this record's cell does not, and we are not going to imply that one is included here.

Working backwards from the pump, three things are yours to specify and none of them are on this sheet: the suction line and its fittings, the valve at the tank, and whatever strainer sits before the impeller. Run the line short and keep it below the outlet where the ground allows it, because a horizontal shell gives up its liquid head quickly as the level drops and a pump fighting for suction at the bottom of a draw is the most common complaint on a tank this shape.

Above the pump line, the 16 inch threaded vented manway is the only other opening named anywhere on the record. It is the fill point, the access point and the vent in one closure, which means whatever you do up there has to leave the vent free to breathe while product is moving out of the bottom.

What a 1.5 grade line actually settles

A grade line settles one thing and it is worth being exact about which. This sheet prints 1.5 and puts 46600 lb beside it as the maximum contents figure, with 31066 lb printed as the mass of water this shell holds at 8.34 pounds per gallon. Those are the maker's numbers. They tell you the tank is published for a liquid heavier than water up to the printed figure, and they tell you nothing whatsoever about whether any particular liquid belongs in polyethylene, which is an entirely separate question and one we will answer properly rather than by reading a weight cell.

The second published limit is the service ceiling of 120 F / 48 C, and the third is freight class 300, printed without an NMFC number. Those three cells plus the dimensions are the specification; everything else on the record is blank and we are leaving it blank.

For background, our article on what happens inside a blend tank when a heavy liquid layers itself, and the field checks that catch it before the load goes out wrong is the single most useful thing to read before you fill a body this size with anything denser than water. Our overview of how the leg and applicator tank ranges are grouped and what each grouping covers explains where this shape sits in the wider family, and our piece on the loaf-style portable utility bodies and the questions a farm fleet has to answer about them covers the small movable tanks people put beside a fixed one.

Which liquids, at what concentration, with which fitting

Each entry pairs a rated liquid with its concentration limit and the fitting and gasket to order alongside the tank. The full rating sits on the linked page and in the chemical compatibility database before ordering.

• Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets)
• Aluminum Sulfate at 50% (PVC, EPDM)
• Calcium Chloride at 40% (PVC, EPDM)
• DEF at 32.5% (316SS fittings, EPDM)
• Ferrous Sulfate at 20% (PVC, EPDM)
• Magnesium Chloride at 30% (PVC, EPDM)
• Sodium Carbonate at 30% (PVC, EPDM)
• Urea Solution at 50% (PP/PVC, EPDM); and Ozonated Water up to 10 PPM (PVC fittings, EPDM gaskets). Ozonated Water does not have a dedicated chart page on

Three plants on one part number, 1320 lb on the scale

The plant list on 44047B names three: St. Bonifacius, Minnesota; Shawnee, Oklahoma; and Fairfield, Texas. The ship-from cell names only Minnesota and Texas. The sheet gives both lists differently and we print both rather than picking one, because which plant supplies your order is the thing that sets the lane. Mode is LTL at freight class 300, and 1320 lb spread across a 145 by 92 inch footprint is a light load in a large space. Get the number for your own ZIP from the freight cost estimator; the listed price is before freight.

Receive this one by the part number first. 44047B and 44049B differ by one digit on paper and by nothing at all in outline on a trailer, so before anything is unstrapped, read the part number off the tank and off the paperwork and make them agree out loud with the driver standing there. That check takes ten seconds and it is the only moment it can be made for free; once the truck leaves with a signature on the note, a swapped part number becomes a return rather than a correction.

Keep the delivery note with the part number circled on it in the job folder, because in two years that circle will be the fastest answer to which of the two 3725 gallon rows you actually own. Tape a copy of the spec sheet inside the control panel door; the next person to touch the tank will not have the box it came in.
