Norwesco 6500 Gallon Black Vertical Storage Tank

The outlet cell, read straight

The pump route reads off the top two rows of that table. A 3 inch bulkhead with a 2 inch reducer in the box gives you one honest choice to make and it should be made on paper before anything is threaded: either the installation is 3 inch from the wall to the pump, or it steps down once at the wall and stays 2 inch. What kills transfer rates on tanks like this is neither size but the installation that changes size twice and then wonders why the pump is noisy.

The 150 inch shell does the priming work for you, since a full tank stands that column of liquid above the port and a pump beside the tank starts flooded. That same column loads the gasket, so put the weight of the suction line on a stand outside the tank and put a union in it before the first valve; on a vessel holding 54210 lb of water, a breakable joint is the difference between a repair and a project.

A dash in the inlet row is all this listing says about filling, which means one published port and a manway that serves as the fill route unless you add something. That manway is vented and the vent is not decoration: it lets air in while the pump pulls out, and covering it is the fastest way to damage a poly shell. The install specific: check that the vent is clear at the same moment you check the level, every time, and build the access arrangement so that is convenient rather than heroic.

The 6500 gallon records, compared row by row

Four rows print 6500 gallons and the first three of them print an identical shell, which tells you that the choice here is never about volume and rarely about shape. It is about the cells each record publishes for itself, and the ones belonging to 40224B are at the top of this page: grade 1.5, contents 81315 lb, a three year warranty cell, a 3 inch port with a 2 inch reducer and a 16 inch vented manway. Read the equivalent cells on any row you are comparing, on that row's own page.

The bottom two rows change the geometry rather than the version. 40764 comes down to 140 inches on the same circle at 6100 gallons; 47620B stands 196 inches tall on a much tighter 102 inch circle for 6502 gallons, which is the answer when floor area is what you are short of. This record sits in the middle of that trade, a 119 inch plan at 150 inches, and that shape is a large part of what 40224B's own sheet argues for.

What 40224B's own sheet argues for

The duty is ordinary bulk liquid storage and the sheet describes it in two cells. The specific gravity cell reads 1.5 and the maximum contents cell reads 81315 lb, against a water reference of 54210 lb for a full shell at 8.34 pounds per gallon. A buyer with a water duty is a long way inside those figures; a buyer with something denser has the ceiling printed and can check it before ordering rather than after.

Beyond that the record is deliberately quiet. No application, no chemistry, no process, no structural provision. It gives a shell, a port, an opening, a grade line, a ceiling, a temperature limit of 120 F / 48 C and a warranty cell reading three year, and everything else is specification work done with your liquid supplier's data in hand.

The honest limitation is the top of the tank. The manway is twelve and a half feet up and nothing on this sheet provides a ladder, a platform or an anchor point for one, so safe access is a separate design and a separate cost. Work it out while the tank is on a trailer and it is a sensible purchase; work it out afterwards and it is a hire.

Reading list for a 6500 gallon install

Foundation first, always: our pad sizing guide for above-ground polyethylene tanks covers how the load from a perimeter ring is handled and where a general framework stops being the right tool. With 54210 lb of water above it, the slab is the part of the job worth over-thinking.

Then the duty. Roof-caught supply is covered by our first-flush diverter guide, which is about what you keep out of the tank. A standing reserve on a remote property is covered by our reservoir design guide, freeze protection included. Recovered process streams are covered by our reuse topology and staged-train piece.

And do the volume properly rather than by habit. The sizing calculator works from draw rate and refill interval; the sizing guide deals with the case where the answer will not fit the space and something has to give.

Thirteen hundred and forty-six pounds to unload

The crate line reads 119 by 119 by 150 inches at 1346 lb, the same number as the empty weight cell, so nothing is published for packaging. Class 300, LTL, two plants, Minnesota and California. With origins that far apart the lane is what sets the bill, so price it against the ZIP it is going to in the freight cost estimator before the order goes in; the listed price is before freight.

Walk the base radius all the way round while the banding is still on. The bottom edge of a vertical shell is where the load has been sitting for the whole trip, it is the surface that will be pressed against your slab for the next twenty years, and it is the one place that is easy to look at on the trailer and almost impossible to look at afterwards. Take one slow lap with a hand on the radius; you are feeling for a flat or a gouge, not looking for one.

Sign the bill with whatever you found written on it, then set the tank down once, on the pad, and leave it there. Leave room to walk all the way around it; the side of the tank nobody can see is the side that leaks.
