Snyder Industries 2500 Gallon HDPE Vertical Liquid Storage Tank in Black

The heavy wall in black

A 1.9 specific gravity wall is sized for a liquid nearly twice as dense as water, and 560 pounds of resin is what that takes at 2,500 gallons, 110 pounds more than the general-grade tanks in this shell; the black pigment adds ultraviolet resistance on top of the wall, which is what makes this the 2,500 to leave outdoors for decades with a dense liquid in it. The wall is sized under ASTM D1998; the HDPE tank wall thickness guide explains that logic and why a tall wall is inspected in the headspace. Full, it puts 39,615 pounds on a 90 inch circle at the rating, which a slab in full contact carries, and the empty tank is strapped against wind. The 2,500 gallon vertical tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator sizes the tank to feed rate and delivery interval, and the tank sizing guide covers the reserve.

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

The N45 is this same 1.9 wall in white with ASTM certification, and the N43 the certified 1.5 wall, 110 pounds lighter; the C37-BLACK is the general-grade black water tank and the C26 the general white. The 5050000C26 is the 2,000 gallon step down on this base, 19 inches shorter, and the 8390000C26 lays 2,650 gallons down to 97 inches on a 102 inch base.

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.

Access and outlet

• Access: 18 inch threaded, vented manway, 107 inches up; vent outside on anything that fumes, fill through a dip tube, and size the vent for a delivery truck's unload rate.
• Outlet: name the liquid when ordering so the bulkhead fitting matches it; a flexible connector between the bulkhead and hard pipe, and the valve supported off the pad.
• Service limit: 120 F / 48 C.

The black wall hides the level, so tee a sight tube off the outlet or fit a sender read at ground level; fit a low-level float switch so a pump never runs dry. On a chemical, choose the sender for the liquid and keep the manway closed against vapor loss. If winters freeze, wrap or drain the outlet valve and the first pipe run; the body takes ice from the top down without harm.

Put to use

A fire reserve of the kind the fire-water reservoir design guide describes, where the black wall keeps the water clean while it waits and the heavy wall outlasts the building; well storage in full sun; and a light-sensitive chemical or a dense brine at a plant with a berm. One liquid per tank, labeled.

How it ships

At 90 inches across and 107 inches long on the deck the 5090000N49 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator prices the move to your ZIP, and the price on this page is before freight. A forklift with long forks sets 560 pounds on the pad. Strap it, fill it to the manway once, hold it, and check the outlet fitting before it goes to work. A strap that is checked once a season is a strap that holds; put it on the same calendar as the gutters.
