Norwesco 4035 Gallon HDPE Horizontal Elliptical Leg Tank in Black

Sixteen feet of tank for one liquid

The duty that brings a buyer here is a large single volume of something heavier than water, held in one body rather than split across several. The sheet supports both halves of that: 4035 gallons, the largest capacity in either of my batches, and a 1.9 rating written as a maximum of 15.87 pounds per gallon with a maximum contents weight of 63939 lb. Water is 33652 lb in the same tank. A 5 year term sits alongside those figures, which is the sheet describing a record meant for long service rather than a season.

The shape is what makes it possible. This body takes its 4035 gallons by running sixteen feet along one axis while standing only 75 inches tall, lower than every other leg tank in this batch. That is a deliberate trade and it suits a specific kind of site: one with length to spare and a height restriction, a low roof line, a canopy or a working height that a taller body would fight. It also puts the top opening lower than any other leg tank in this batch, which changes the fill route from a structure question to a step question.

What it asks in return is the ground. Sixteen feet of continuous, level, load-bearing support, with genuine contact under each leg rather than under the ones that happen to land well, proven with a straightedge along the full length before the tank is unstrapped. A long body magnifies a small dip: the far end is where you will see the consequence and the middle is usually where it starts. If the volume is still open, the tank sizing calculator works it from a duty cycle and the tank sizing guide covers whether the gallons belong in a long low body or a tall one.

Four 4035 gallon rows and a 3250 for scale

Two black rows appear in this table at two different weights, 1320 lb and 1160 lb, which is the clearest warning in this family that the colour word is not the specification. This record is the heavier black one. It shares its weight with the blue row and shares nothing but its colour name with N-45394, whose figures live on its own sheet. All four 4035 gallon rows occupy identical space, so the envelope is never the deciding factor inside this family; the published weight, rating and term are. The 3250 gallon row is there for scale: 152 inches long, 88 wide, 82 tall, and a different amount of liquid entirely. If your site has the height but not the length, that is the direction to look.

Suction from a 3 inch bulkhead on a 75 inch tall body

• The draw-off sets the design: a 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer. The shell gives you three inches; the reducer hands two inches to the line.
• Match the pump to the two inch route and keep that route short. On a body 192 inches long, the temptation is to run the suction line the length of the tank to a convenient spot; resist it, and put the pump near the outlet instead.
• No siphon tube is named on this record, so read the outlet field as the complete description of what is fitted and specify anything else yourself.
• The bulkhead is a sealed penetration through the wall: hand-tight first, no wrench force against the shell, every pipe run supported independently.
• Valve tight to the tank, union immediately downstream. Without the union, servicing the line means moving 4035 gallons first.
• Access is a 16 inch threaded vented manway with a matching 16 inch lid size field. At 75 inches, that opening is lower than on any other leg tank in this batch, which makes routine access genuinely easier; the vent still stays clear at all times.
• The ceiling is 120 F / 48 C and the term is 5 years.

The honest limitation on this record is length. Sixteen feet of tank is easy to specify on paper and hard to place: it needs the run, it needs the access down one side, and it needs the delivery vehicle to be able to reach the position. The install specific to keep: mark the leg positions on the pad before the tank is lifted, so the set is a placement rather than a series of adjustments with a loaded machine and 1320 lb swinging.

When one 4035 replaces a pair of smaller tanks

Consolidating two tanks into one is usually the reason a record this large gets specified, and it changes the operating question from plumbing to liquid behaviour: what happens inside 4035 gallons that stands still. Our field study on stratification, thermal layering and the checks that catch it is the direct answer to that. Our article on pigment chemistry in polyethylene tanks explains why colour turns up in a part number at all, which is the question this family provokes. Our explainer on Norwesco applicator and leg tanks and the scope they are sold under and our piece on loaf-style portable utility tanks cover the two alternatives buyers weigh against a body this size. What this page commits to is the record: 4035 gallons, 192 x 92 x 75 inches, 1320 lb, 1.9 and 15.87 pounds per gallon, 63939 lb maximum contents, a 3 inch bulkhead with a 2 inch reducer, a 16 inch vented manway, 120 F / 48 C and 5 years.

Rated chemistries for this tank

The manufacturer lists these liquids for this resin at the concentrations noted, with the fitting and gasket material to specify. Check the concentration and temperature you actually run on the linked page or in the chemical compatibility database before ordering.

• DEF at 32.5% and
• urea solution at 50% (316SS and PP/PVC fittings, EPDM gaskets) - common high-density ag and emissions loads. Within its rating it is also compatible with
• acetic acid (60%, PP/PVC, EPDM)
• aluminum sulfate (50%, PVC, EPDM)
• calcium chloride (40%, PVC, EPDM)
• ethylene glycol (100%, PVC, EPDM)
• ferric chloride (50%, PVC, EPDM)
• ferric sulfate (60%, PVC, EPDM)
• ferrous sulfate (20%, PVC, EPDM)
• hydrochloric acid (37%, PVC, Viton)
• hydrofluoric acid (48%, PP/PVC, Viton)
• hydrofluosilicic acid (26%, PP/PVC, Viton)
• hydrogen peroxide (50%, PVC, Viton)
• magnesium chloride (30%, PVC, EPDM)
• peracetic acid (30%, 316SS, Aflas)
• phosphoric acid (85%, PVC, Viton)

• sodium carbonate (30%, PVC, EPDM)
• sodium hypochlorite (under 16.5%, PVC, Viton)
• sodium thiosulfate (40%, PVC, EPDM)
• sulfuric acid (98%, CPVC, Viton)
• zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). Match the fitting and gasket material to the chemical, not just the tank.

Five plants, and the widest lane choice in this family

This record names more origins than anything else in either of my batches: St. Bonifacius, Minnesota; Lancaster, Ohio; Hanford, California; Fairfield, Texas; and Philippi, West Virginia, with a ship-from field listing California, Minnesota, Ohio, Texas and West Virginia to match. Five plants across five states is a real advantage on a tank this size, because the freight bill on a 192 inch body is dominated by distance and a nearer origin is worth more than any other saving available on the order. Freight class and ship mode both read OVS. Run your ZIP through the freight cost estimator and ask us which origin is being used; the listed price is before freight. When it arrives, receive it along its length: walk the full 192 inches on both sides with the tank still on the trailer, because a long body is loaded and blocked at a few points only, and those points are where anything worth finding will be. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
