Snyder Industries 1000 Gallon Black Heavy Duty Vertical Storage Tank

The round number, in the heavy wall

When a drawing says a 1,000 gallon chemical tank, it usually means a tank on a five foot base under an eight foot ceiling with a pump beside it, and this one is that tank in black. Black polyethylene ages far slower than white in the sun and keeps a light-sensitive chemical at strength; it runs warmer, so shade if the liquid must stay cool, and it hides the level, so a sender read at the pad goes in with the tank. Full at the rating it puts 15,846 pounds on a 60 inch circle, a heavy load per square foot, so it stands on an engineered slab per the concrete pad sizing guide, inside a berm sized to the tank when the liquid is regulated, strapped at the top third while it is empty. 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.

Grades on the 60 x 89 inch tank, and the 850 and 1,100 beside it

The N40 and N46 are the other chemical grades in this shell, and the N42 the cross-linked one for hypochlorite and peroxide at 40 pounds more resin on the sheet. The 1810000C34 stands 850 gallons on a 48 inch base at 117 inches for the narrowest floor, the 1830000C34 is the 1,100 on a 64 inch base at this tank's height, and the 1710000C26 lays 1,100 gallons down to 55 inches on an 86 inch base.

Two rows look the same? The difference is the wall; call 866-418-1777 with the liquid and we will say which, or ask for a quote on both.

Outlet, manway, vent

• Outlet: 2 inch polypropylene female NPT bulkhead fitting, at the base; a flanged transition, a flexible connector to hard pipe, and the valve supported off the pad in the material the chemical calls for.
• Access: 18 inch threaded, vented manway, 89 inches up, reached from a step; fill from a truck or a tote through a dip tube, vent outside on anything that fumes, and size the vent for the delivery pump.
• Service limit: 120 F / 48 C.

Seven feet of liquid above the outlet keeps a pump's suction flooded to the last inches; mount the pump below the outlet so it primes by gravity, and put a low-level float on it. The sender is the gauge on a black wall. Keep the manway closed against vapor loss, label the one chemical the tank holds, and where it freezes, wrap or trace the outlet valve and the first pipe run; the body takes ice from the top down without harm.

Where a specified 1,000 goes

The coagulant or the caustic tank at a small water plant, the acid supply at a cooling tower, a chemical tank at a lift station, the makeup tank on a plating line, and the bulk tank behind a chemical feed skid. 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 wants 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

The 1831000C34 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. A forklift with long forks sets 260 pounds on the pad, or three people walk it empty; at 60 inches across it goes through a double door upright. Fill it with water to the manway once and look at the outlet fitting and the pad edge, then drain and dry before the chemical goes in. The vent screen is the cheapest part on the tank and the one that saves it. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
