Snyder Industries 1900 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Nearly two thousand gallons on a five foot circle

A water-rated wall is for water and nothing heavier; the heaviest wall is for concentrated acid; a 1.5 wall is the middle, sized for brine, fertilizer solution and coagulant as delivered and every water application, with margin. 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 a tall, narrow wall is inspected from the top, in the headspace. Full, it puts 23,769 pounds on a 64 inch circle at the rating, the most concentrated floor load in its size class: a slab in full contact under the whole floor, per the concrete pad sizing guide, with the tank strapped at two heights, because a 64 inch base under twelve feet of liquid has a high center of gravity. The tank sizing calculator tells you whether 1,900 gallons covers the draw, and the tank sizing guide covers days of supply.

The 64 x 147 inch pair, and the sizes beside them

The N45 is the 1.9 wall in this same shell, 50 pounds heavier, for ferric at strength and the heavy brines. The 1780200 tanks hold the same 1,900 gallons on a 72 inch base at 119 inches, 28 inches lower, the N40 and N42 in cross-linked resin for oxidizers; the 32118 lays 1,600 gallons of water down under 71 inches, and the 5050000C26 holds 2,000 gallons on a 90 inch base at 88 inches.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

Connections

• Access: 18 inch threaded, vented manway, 147 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: tell us the liquid when ordering and the bulkhead fitting is matched to it; a flexible connector between the bulkhead and hard pipe, and the valve supported off the pad.
• Service limit: 120 F.

On a tank this tall nobody reads a level by eye from the top; the white wall shows it in daylight from the ground, and a sender read at ground level with fit a low-level float switch so a pump never runs dry. Mount the pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and keep the tank out of direct sun where the liquid is light-sensitive. Where it freezes, insulate or drain the outlet valve and the first length of pipe; the body takes ice from the top down without harm.

When the delivery truck arrives

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; on a shell this tall that is a long drop. Somebody stands at the tank for the whole of the first delivery, watching the slab edge and the outlet fitting as the level rises, and the log takes the date and strength of every load that follows.

What it holds in practice

Treatment chemicals in the corner of a plant room, brine for a softener bank, well storage for a house and a garden where the pad is small, fertilizer solution at a farm, and a fire reserve of the kind the fire-water reservoir design guide describes, where twelve feet of head gives a pump a flooded suction. One liquid per tank, labeled.

Getting it to the pad

At 147 inches long on the deck the 8300000N43 ships as oversize freight at a lane rate rather than a class rate; the freight cost estimator prices the move to your ZIP, and the price on this page is before freight. Two people stand 460 pounds with a strap and a helper on the top, or a forklift does it; at 64 inches across it goes through a double door. Fill it to the manway once, hold it, and check the outlet fitting before the pump goes on. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
