Snyder Industries 550 Gallon Heavy Duty Vertical Storage Tank

Two totes, one tank, one pallet

A plant that takes two totes a delivery is handling two cages, two valves and two half-empty containers; a 550 gallon tank on a pad takes both pumped over and keeps one fitting, one valve and one float in one place. The 1.9 wall covers the dense chemicals a tote does, and the white wall shows the level through it in daylight. Full at the rating it puts 8,715 pounds on a 48 inch circle, which is a heavy load per square foot, so it stands on a level slab per the concrete pad sizing guide, inside a berm sized to the tank when the liquid is regulated, and strapped at the top third, because six feet of empty polyethylene on a four foot base goes over in a gust or a bump from a forklift. The tank sizing calculator turns feed rate and delivery interval into a volume, and the tank sizing guide covers the reserve to keep the pump wet between deliveries.

The 48 inch 550 in its grades, and the low 550 beside it

The 1800000C34 and N51 are the black tanks in this shell for sun or a light-sensitive liquid, and the N48 the other chemical grade. The 8060000C26 is the same 550 gallons laid down to 46 inches on a 64 inch base for a site with floor and no height. The 5780100N42 is the 500 gallon cross-linked tank for oxidizers, and the 1700200N42 the 710 in that resin on a 60 inch base.

Outlet, manway, limit

• Outlet: 2 inch polypropylene female NPT bulkhead fitting, at the base; a flexible connector to hard pipe, the valve supported off the pad, and the reducer to the pump's suction at the pump.
• Access: 18 inch threaded, vented manway, 75 inches up, reached from a step; fill from a tote through a dip tube so the liquid does not free-fall and foam, and vent outside on anything that fumes.
• Service limit: 120 F / 48 C.

Six feet of liquid above the outlet keeps a pump's suction flooded to the last inches, and the 2 inch fitting drains the tank in minutes for a chemical change. Mount the pump below the outlet so it primes by gravity, put a low-level float on it, keep the manway closed against vapor loss, and label the one chemical the tank holds; if the tank ever moves on its pallet, the pipe comes off at the flexible connector, not at the bulkhead.

Plants that pick the 48 inch 550

The acid or caustic supply at a boiler room, a coagulant or a polymer tank at a small water plant, a plating line's makeup tank, the brine tank behind a large softener, and the chemical supply on a truck wash. If the liquid warrants a second wall, the Captor double wall freeboard guide explains what a contained tank gives up in usable volume at this size. Not a fire tank; the fire-water reservoir design guide works in thousands of gallons and a water wall, and where a reuse system doses treatment chemical between storage stages, the industrial water reuse tank topology article shows where a tank this size sits.

Freight from Chowchilla, on the pallet it will live on

The 1800400C26 ships from Chowchilla, California as LTL freight at class 300; the freight cost estimator quotes it to your ZIP, and the listed price is before freight. Two people stand 110 pounds, or a forklift moves it on its pallet; at 48 inches across it goes through a double door upright. Fill it with water to the manway once and look at the outlet fitting for a weep, then drain and dry before the chemical goes in. Keep the pallet; a tank that moves again is easier to move on it. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
