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

The middle wall, certified, on the low base

A water-rated wall is for water and nothing heavier; the chemical wall is what concentrated acid needs; a 1.5 wall is the middle, sized for brine, fertilizer solution and coagulant as delivered and every water application, with margin, and 510 pounds of resin is what it takes on this wide, low shell. ASTM D1998 is the standard the certification is written to, and a tank meets it in the wall; the HDPE tank wall thickness guide explains the sizing logic and why the headspace is where a wall ages. Full, it puts 31,275 pounds on a 96 inch circle at the rating, which a compacted gravel pad or a slab in full contact carries, and the wide base sits low enough that no strap is needed. The 2,500 gallon vertical tank buyers guide compares the shapes at this volume across makers; 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 96 x 98 inch tank, and the sizes beside it

The 5090300N39 is the certified 1.35 wall in this same low shell, 110 pounds lighter, for water and hypochlorite. The 5090000N43 is this same certified 1.5 wall on a 90 inch base 9 inches taller and 60 pounds lighter, the 5090000N45 the certified 1.9 wall on that base, and the C26 the general grade. The 5050000C26 is the general 2,000, and the 8390000C26 holds 2,650 gallons on a 102 inch base at nearly this height.

Bulkheads and lid

• Access: 18 inch threaded, vented manway; fill by hose or truck down a dip tube, and vent to the outside if the liquid fumes.
• Outlet: name the liquid when ordering so the bulkhead fitting matches it; hard pipe joined to the bulkhead through a flexible connector, valve on a bracket of its own.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

The white wall shows the level in daylight; a float switch for low level protects a pump, and the low shape keeps the suction flooded to the last few inches. The pump sits below the outlet so it primes by gravity; the manway stays closed; a light-sensitive liquid stays out of the sun. Insulate or drain the outlet valve and the first run of pipe wherever the ground freezes.

Receiving a delivery

A delivery truck's pump moves liquid faster than a manway vent passes air, so the vent is sized for the unload rate or the fill comes in through a top bulkhead with its own vent line. Run the fill pipe to the floor so the liquid does not free-fall and foam. The first delivery into a new tank is watched from start to finish, with the outlet fitting checked as the level climbs, and every delivery after that goes in the log with a date and a strength.

Day-to-day duty

Brine for a softener bank, fertilizer solution on a farm, coagulant as delivered at a small plant that needs the certification on file and has a lower roof, well storage, and a fire reserve of the kind the fire-water reservoir design guide describes, where the low center of gravity counts. One liquid per tank, labeled.

From the plant to your site

At 96 inches across the 5090300N43 is oversize freight (NMFC 156600-01) on a flatbed at a lane rate; the freight cost estimator quotes the haul to your ZIP; what is listed is the price before freight. A forklift with long forks sets 510 pounds on the pad. Fill it to the manway once, hold it, check the outlet fitting, and keep the certification paperwork with the project file. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
