Snyder Industries 440 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Two totes, certified, under six feet

Four hundred forty gallons is nearly two totes with room for expansion and freeboard, and a 53 inch base under 69 inches holds it beside a dosing skid without a forklift aisle. The wall is sized for a liquid nearly twice as dense as water and certified against ASTM D1998, the standard rotationally molded polyethylene tanks are specified to; the HDPE tank wall thickness guide explains the D1998 sizing logic and why the vapor headspace is where a wall fails first. Full, it puts 6,972 pounds on a 53 inch circle at the rating; a slab in full contact carries that, and the concrete pad sizing guide covers a shared slab. The tank sizing calculator sizes the tank to feed rate and delivery interval, and the tank sizing guide covers the reserve.

Grades on the 53 x 69 inch tank, and the sizes beside it

The N42 is cross-linked polyethylene for hypochlorite and the other oxidizers, and the N48 and N51 are other linear grades, all at this tank's weight in the same shell. The 1740000N48 holds 400 gallons on a 45 inch base 7 inches shorter and 45 pounds lighter, and the 5780100N42 is the cross-linked 500 on this same 53 inch base, 8 inches taller.

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.

What is fitted

• 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 69 inch tank shows its level in daylight; a low-level switch protects the pump. Set the dosing pump lower than the outlet so gravity primes it, keep the manway shut so nothing is lost as vapor, and shade the tank if the chemical is light-sensitive. A 53 inch tank fits a standard spill pallet, which is where a single wall chemical tank stands. Put a union and a check valve in the suction line so the pump can be serviced without draining the tank, and run the vent to the outside on anything that fumes.

Applications

Treatment chemicals at a small system that needs the certification on file, brine for a softener bank, acid and inhibitor feed at a cooling tower, polymer make-down on a skid, 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.

On the truck

The 5770100N45 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 130 pounds, and at 53 inches across it needs a wide door. Fill it to the manway once, hold it, check the outlet fitting, and keep the certification paperwork with the project file. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
