Norwesco 1625 Gallon Black Horizontal Leg Tank

Five rows at or around 1625 gallons

Four catalogue numbers share the top block of that table: 1625 gallons in a 139 by 63 by 68 inch body, four times over. The weight column is the only one that moves and it does not move the way you might expect. This record prints 449 lb. 40834 prints 514 lb. N-40133 prints 514 lb as well, the same figure as 40834 in the same envelope. N-40026 prints nothing. Four rows, three distinct entries in one column, and no explanation anywhere on the sheet for any of it. We put the figures down as the catalogue has them and leave the reasoning where the maker left it, which is unstated.

The bottom two rows are the capacity steps and they move in different directions dimensionally. 42335 gives up three hundred gallons and forty inches of length but takes back three inches of width and two of height. N-42990 buys another hundred and seventy-five gallons for seven more inches of length at the same 68 inch height and a slightly narrower 62 inch width. So between 1325 and 1800 gallons the height barely changes at all: this whole part of the range lives between 68 and 70 inches tall, and the planning variable is the run of floor.

Why the 63 inch width is the point of this record

Set this row beside the 1325 gallon record the sheet prints below it and the difference is not what people assume. 42335 is 66 inches wide and 70 inches tall in a 99 inch length. This record is 63 inches wide and 68 inches tall in a 139 inch length. It holds three hundred more gallons in a body that is narrower and lower than the smaller tank, and pays for it entirely in length.

That is a genuinely useful thing to know when a site is planned. If the aisle, the gate or the space between two fixed points is the constraint, moving up a capacity here does not cost you width, it gives you a little back. If the constraint is a wall-to-wall run, the smaller capacity is forty inches shorter and that is the end of the argument. Take the tape to the site before you take the catalogue to it, and let the binding dimension choose the row.

The honest limitation is the one the family table already showed: two of this record's relatives publish the same 514 lb weight in the same envelope and a third publishes none at all. The sheet neither reconciles nor explains that, and neither will we. If one of those part numbers is what you are being offered somewhere else, ask us and we will have the cells confirmed in writing rather than guess at them. The tank sizing calculator and the sizing guide settle the gallons while that question is out with the factory.

What 20329 lb of contents means on this record

The contents figures on this sheet are the largest in its family and they deserve reading slowly. The grade cell is 1.5. The maximum contents cell reads 20329 lb. The water figure is 13552 lb at 8.34 pounds per gallon, which is what 1625 gallons of water alone comes to. Those three are the maker's own entries and they go straight into a specification; anything past what they support is a written question to the factory and we will ask it rather than round it off for you.

Read the water figure as a groundworks number as well as a contents number, because this is the point in the family where the weight of a full tank stops being an abstraction. Thirteen and a half thousand pounds of water standing on a 139 by 63 inch footprint is a real load on whatever is underneath it, and a surface that seemed fine under an empty 449 lb shell will tell you a different story a month after the first fill. The service ceiling, 120 F / 48 C, is the other published limit, and on a body this size it is a siting consideration rather than a footnote.

Three pieces of reading that earn their place around a tank this size. Our article on the layers that form in a standing blend and the checks that catch a separated load before the spreader does matters most at the top of a capacity range, because the biggest tank on a site is the one that stands longest between uses. Our overview of where the maker draws the line between its applicator bodies and its leg tanks puts this shape in its catalogue context, and our piece on the low loaf-style utility bodies that fleets run alongside their leg tanks is the alternative worth understanding before you accept 68 inches of height.

The top opening breathes and the wall port drains

• Top opening: a 16 inch threaded vented manway. It is the only route for air on the entire record and, because the inlet cell is blank, it is also the fill point the sheet supports.
• Wall port: a 2 inch PP female NPT bulkhead fitting, polypropylene body, female national pipe thread. The only liquid connection published.
• Not published: an inlet, a lid-size figure, a structural detail, an application text or an NMFC code. Five empty cells, printed here as empty.

The air path is the line to think hardest about on the largest tank in its family. One vented lid has to handle everything the liquid level does, and the faster a 1625 gallon body is filled or emptied the more air has to go the other way through that single 16 inch opening. Filling by hose and drawing by gravity never tests it. A pump does, immediately, and the sheet carries no figure that would tell you where the limit sits. Put that to the factory before the pipework is built and we will get an answer in writing.

The install specific follows directly from the first bullet and it is the one thing on this page most likely to save a mess. Because the vented manway is both the air path and the fill point, do not be tempted to fill this tank backwards through the 2 inch bulkhead to save running a hose to the top. A fill pushed in at the bottom of a sealed-but-for-one-lid body relies entirely on that same lid to let the displaced air out at the same rate, and it puts the fill line on the one fitting you also depend on to drain. Fill through the top, draw through the wall, and keep the two jobs on separate openings.

One plant, 449 lb, and a lid to turn by hand

Washington Court House, Ohio is the only plant on this part number and Ohio is the only entry in the ships-from cell. On a family where most records come out of five or six places, this one comes out of one, which means there is a single lane and no fallback if that plant is busy. Plan the date with that in mind rather than assuming the flexibility the rest of the range has. The mode is LTL and the freight class is 300, which is what 449 lb in a 139 by 63 by 68 inch envelope earns: a very large amount of trailer for very little weight, priced on the space. Get the number from the freight cost estimator with the delivery ZIP in it before you commit to anything; the listed price is before freight.

When it arrives, put a hand on the lid before you put a fork under the tank. Unscrew the 16 inch vented manway, look at the threads on both the lid and the neck in daylight, and screw it back down by hand. A threaded lid is the one component on this tank that is fitted by a person rather than moulded with the body, and it is the one that can be cross-started at the plant, knocked at a transfer point or left half-turned, none of which shows from ten feet away. If it does not run down smoothly by hand, stop there and tell us before the tank is unloaded.

Then leave the lid slightly loose until the day of the first fill, so nobody arrives to a tank they cannot open and reaches for a bar. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
