Snyder Industries 330 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

What 108 pounds of resin is for

A rotationally molded tank's empty weight is its wall thickness, and 108 pounds against 85 in the squat certified tank of this volume is a shell that resists creep under a dense liquid, holds its shape through years of sun and thermal cycling, and carries a valve and hard pipe at the outlet without oval-ing the fitting; the extra 18 inches of height give a pump more head and the wall more room for freeboard. The certification is against ASTM D1998; the HDPE tank wall thickness guide explains the sizing logic and why inspection happens above the liquid line, and the freeboard sizing guide works out how much of the nominal 330 gallons is usable once thermal expansion is accounted for. Full, it puts 5,229 pounds on a 47 inch circle at the rating; a paver pad or a slab in full contact carries that, and the concrete pad sizing guide covers a shared slab. The tank sizing calculator sizes a day tank to the pump's rate and the refill schedule, and the tank sizing guide covers the reserve.

Snyder's 300 to 360 gallon verticals

The 1008200 tanks are the squat 330s on this same base, 18 inches shorter: the N45 certified, the N52 opaque and heavy-walled at this tank's weight, the N42 in cross-linked resin for oxidizers. The 1011200C26 is the doorway 300 on a 35 inch base, and the 5760100N42 lays 360 gallons down to 59 inches on a 53 inch base in cross-linked resin.

Bulkheads and lid

• Access: 18 inch threaded, vented manway; hose or tote pump fill through a dip tube; vent outdoors on a fuming liquid.
• Outlet: name the chemical when ordering so the bulkhead fitting matches it; a flexible transition to the pump suction and a valve supported off the floor.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white 68 inch tank shows its level in daylight; a low-level switch protects the pump. Mount the dosing pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and inspect above the liquid line, in the headspace, where a wall fails first. A 47 inch tank fits a standard spill pallet.

Day-to-day duty

Treatment chemicals at a small system that needs the certification on file and works the tank hard, brine for a softener, acid and inhibitor feed at a cooling tower, an outdoor day tank in full sun, and, with water in it, a well buffer or one cell of the small reserve the fire-water reservoir design guide describes. One chemical per tank, labeled.

From the plant to your site

The 5750100N45 ships palletized as LTL freight (NMFC 156600-01) at a class rate; the freight cost estimator quotes it to your ZIP, and what is listed here is the price before freight. Two people carry 108 pounds. Check the manway and the outlet fitting, fill it once with water to prove the seal, 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.
