Snyder Industries 2500 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Half a tanker under nine feet, at the lightest rated wall

A 1.35 specific gravity rating is the step between the water wall and the middle grade: alum and most fertilizer solutions come in lighter than that, so this tank carries them with margin at the least resin of the three rated walls in this shell. Rotationally molded polyethylene tanks are sized to ASTM D1998, and the way a tank meets the density it is rated for is in the wall; the HDPE tank wall thickness guide explains the sizing logic and why the headspace is where a wall ages, and the freeboard sizing guide works out the usable volume once thermal expansion is accounted for. Full, it puts 29,190 pounds on a 90 inch circle at the rating, which a slab in full contact or a compacted, screeded gravel pad carries, with the empty tank strapped against wind. The 2,500 gallon vertical tank buyers guide walks through the competing shapes at this volume; the tank sizing calculator tells you whether 2,500 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 90 x 107 inch tank, and the sizes beside it

The N43 and N45 are the 1.5 and 1.9 walls in this same shell, for coagulants and brines as delivered and for ferric at strength, and the 5090100N45 is the certified 1.9 wall for a job that needs the paper; the 5090000 tanks are the general grades, the C37-BLACK in black for sun. The 5050000C26 is the 2,000 step down on this base, 19 inches lower, and the 8390000C26 lays 2,650 gallons down to 97 inches on a 102 inch base.

The fittings list

• Access: 18 inch threaded, vented manway, 107 inches up; filled by hose, tote pump or truck through a dip tube, vented outside on anything that fumes, and size the vent for the delivery pump.
• Outlet: specify the bulkhead fitting for the liquid when ordering; a short flexible section after the bulkhead, and the valve supported from the pad rather than the tank.
• Service limit: 120 F / 48 C.

The white wall shows the level in daylight; a float switch at low level shuts the pump off before it runs dry. Set the pump lower than the outlet so gravity primes it, keep the manway shut against vapor loss, and shade the tank if the liquid is light-sensitive. In a cold climate the outlet valve and the first run of pipe are insulated or drained; the body takes ice from the top down without harm.

The truck at the manway

A delivery truck's pump can push air out faster than a stock vent can pass it, so the vent is sized for the unload rate or the fill goes through a dedicated top bulkhead with its own vent line. The fill pipe runs to the floor so the liquid does not free-fall and foam. The first load into a new tank gets watched end to end, eyes on the slab edge and the outlet fitting while the level comes up, and each delivery after it is logged with its date and strength.

What goes in it

Alum and fertilizer solution at farms and small plants, well storage for a house, a barn and a garden, a rain cistern under a large roof, stock water on a pasture, and one cell of a fire reserve, where the low center of gravity counts. One liquid per tank, labeled.

Getting it off the truck

At 90 inches across and 107 inches long on the deck the 8140000N39 ships as oversize freight at a lane rate rather than a class rate; the freight cost estimator gives the flatbed number for your ZIP, and the listed price is before freight. A forklift with long forks sets 427 pounds on the pad, or two people stand it. Fill it to the manway once, hold it, and check the outlet fitting before the pump goes on. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
