Snyder Industries 550 Gallon Black Heavy Duty Vertical Storage Tank

Low, dark, and strapped down

A tank on a trailer lives by three rules: continuous support under the whole floor, a strap over the top, and the outlet valve protected from the road. A low wide tank makes all three easy, and full it puts 8,715 pounds at the rating on the deck, which is the axle question before it is the tank question. On a pad the same low shape needs the least strapping in its class, on a slab in full contact per the concrete pad sizing guide, inside a berm when the liquid is regulated. Black polyethylene ages far slower than white in the sun and keeps water clear of algae, but it runs warmer and hides the level, so a sight tube off the outlet is the gauge that rides with it. 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 low 550s and the tall ones

The 8060000C26 is this tank in white for a tank that lives indoors, and the 1820000C34 its inch-taller black twin from the Chowchilla and Lincoln plants for buyers nearer them. The 1800000 family stands the same 550 gallons up on a 48 inch base at 75 inches, black in the C34 and N51, for a pad with height and no floor. The 5780100N42 is the 500 gallon cross-linked tank for oxidizers, and the 1700200N42 the 710 in that resin, the next low tank up.

Fittings that ride

• Outlet: 2 inch polypropylene female NPT bulkhead fitting, at the base; on a trailer, a valve at the tank and a camlock so the hose comes off for the road, with a guard over the valve; on a pad, a flexible connector to hard pipe and the valve supported off the pad.
• Access: 18 inch threaded, vented manway, 46 inches up, opened from the ground or from the deck; fill through a dip tube, and vent outside on anything that fumes.
• Service limit: 120 F / 48 C.

A black wall hides the level, so the sight tube is the gauge, and a low-level float shuts a pump off before it draws air. The pump sits at floor level and primes by gravity. Keep the manway closed against dust and vapor loss, label the one chemical the tank holds, and where it freezes, drain the outlet valve and the line; the body takes ice from the top down without harm, and a black wall thaws first in the morning sun.

On the road and off it

A nurse tank on a spray contractor's trailer, water on a job site trailer where a white tank would go green, a chemical tank at a lift station, a spray-mix supply against a barn wall, and a low tank under a deck for a rain or a greywater reserve. 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 where a reuse system collects roof water and condensate, the industrial water reuse tank topology article shows where a low dark tank sits in the train.

Freight from Marked Tree or Philippi

The 8060000C34 ships from Marked Tree, Arkansas or Philippi, West Virginia, whichever is nearer, as LTL freight at class 400, the class light, bulky tanks take; the freight cost estimator quotes the lane to your ZIP, and the listed price is before freight. Two people stand 100 pounds; at 64 inches across it goes around the building or onto the trailer by forklift. Fill it with water to the manway once, look at the outlet fitting for a weep, and on a trailer run the same test parked level, then drive it around the block and look again. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
