Snyder Industries 850 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Certified, and all height

A 48 inch base under 117 inches is a column of liquid nearly two and a half times as tall as it is wide, so the tank is strapped to a wall or anchored at two heights, and full it puts 13,469 pounds on that circle at the rating, which a slab in full contact carries. The reward is 850 gallons where nothing wider would fit, with ten feet of head keeping a pump's suction flooded. The certification is against ASTM D1998, and the way a tank meets it is in the wall; the HDPE tank wall thickness guide explains the D1998 sizing logic and why a tall wall is inspected in the headspace. Work out the usable volume once thermal expansion is accounted for with the freeboard sizing guide. The 850 gallon vertical tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator sizes the tank to feed rate and delivery interval, and the tank sizing guide covers the reserve.

Grades on the 48 x 117 inch tank, and the sizes beside it

The N42 is cross-linked polyethylene for oxidizers and the N48 another linear grade at this tank's weight; the C34 is the general grade, 10 pounds lighter. The 5990900N42 lays 750 gallons down to 66 inches on a 68 inch base in cross-linked resin, and the 1831000C34 holds 1,000 gallons on a 60 inch base at 89 inches, 28 inches shorter than this tank.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

Access and outlet

• Access: 18 inch threaded, vented manway, 117 inches up, reached from a platform; filled by hose or tote pump through a dip tube, vented outside on anything that fumes.
• Outlet: tell us the liquid when ordering and the bulkhead fitting is matched to it; a flexible connector to the pump suction, with the valve carried by a bracket rather than the fitting.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white tank shows its level in daylight, and on a tank this tall a sender on the outlet or a sight tube saves the climb; fit a low-level float switch so a pump never runs dry. Mount the dosing pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and keep the tank out of direct sun where the chemical is light-sensitive. A 48 inch tank fits a standard spill pallet, which is where a single wall chemical tank stands.

Put to use

Treatment chemicals at a system that needs the certification on file and has a tall, narrow corner to fill, brine for a softener bank, acid and inhibitor feed at a cooling tower, and, with water in it, a well buffer or a cell of the small fire reserve the fire-water reservoir design guide describes. One liquid per tank, labeled.

How it ships

At 117 inches long on the deck the 1810000N45 ships as oversize freight (NMFC 156600-02) at a lane rate; the freight cost estimator prices the move to your ZIP, and the price on this page is before freight. Two people stand 220 pounds up and walk it into place. Strap it at two heights, water-fill to the manway and hold it, check the outlet fitting, and keep the certification paperwork with the project file. A strap that is checked once a season is a strap that holds; put it on the same calendar as the gutters.
