Snyder Industries 250 Gallon Heavy Duty Vertical Storage Tank

Sizing a feed tank to the delivery, not the pump

A metering pump draws gallons a day; the tank behind it is sized to how often the truck comes and how much it brings, and 250 gallons is the size that takes a tote delivery whole with margin for what was left in the bottom. The 1.9 wall holds the dense chemicals at strength, and the white wall shows the level in daylight, which is the gauge most small feed tanks actually run on. Full at the rating it puts 3,962 pounds on a 36 inch circle, the most weight per square foot of any tank in this family, so it stands on a level slab per the concrete pad sizing guide, inside a berm when the liquid is regulated, strapped to a wall or a post because five feet of empty polyethylene on a three foot base is a sail. The tank sizing calculator does the feed-rate arithmetic, and the tank sizing guide covers the reserve to keep the pump wet between deliveries.

The 36 inch family, and the wider 275

The C34 is the twin in the other general grade, the N42 the cross-linked tank for oxidizers, and the N48 the other chemical grade, all on the same 36 x 64 shell at this weight. The 1012900C26 is the 210 gallon step down, nine inches shorter, and the 5740100N42 puts 275 gallons on a 47 inch base at 59 inches in the cross-linked resin for a site with floor and no height.

Connections five feet up and at the floor

• 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, 64 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.

A tote pump fills this tank in minutes, and a manway at 64 inches means the hose goes in over the rim from the floor, no ladder. Mount the pump below the outlet so it primes by gravity, set a low-level float, and keep the manway closed against vapor loss; a strap at the top third of the wall holds the tank against a bump from a cart. One chemical per tank, labeled, in a spill tray or behind a curb.

Sites that buy this one

The acid or caustic supply at a boiler room or a cooling tower, a coagulant or a polymer tank at a small water plant, the hypochlorite tank at a pool plant when it is the N42, a brine tank for a large softener, and the chemical supply on a wash bay. Not a fire tank; the fire-water reservoir design guide works in thousands of gallons and a water wall. Where a reuse system doses treatment chemical between storage stages, the industrial water reuse tank topology article shows where a tank this size sits.

Getting it in the door

The 1008100C26 ships from Merced, California as LTL freight at class 300; the freight cost estimator quotes it to your ZIP, and the listed price is before freight. One person carries 70 pounds, and a 36 inch tank does not pass a 36 inch door upright; it goes through on its side or through a double door. Fill it with water to the manway once, check the outlet fitting for a weep, then drain and dry before the chemical goes in. Write the chemical and the fill date on the wall in paint marker. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
