Snyder Industries 300 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Certified, tall and light

The certification is against ASTM D1998, the standard rotationally molded polyethylene tanks are specified to, and the way a tank meets it is in the wall; the HDPE tank wall thickness guide sets out how D1998 sizes a wall and why the headspace, not the liquid side, is where failures start. The 18 inch manway admits a fill hose, a float switch and a level sender at once, and a wash-down wand reaches the floor at changeover. Full, it puts 4,754 pounds on a 35 inch circle at the rating, so it is strapped to a wall; a paver pad or a slab in full contact supports the load. The 300 gallon vertical tank buyers guide compares this shape across makers; the tank sizing calculator matches the tank to feed rate and refill schedule; the tank sizing guide covers the reserve.

Snyder's 290 to 330 gallon verticals

The 1630100N45 is the heavy-wall 300 with the same certification, 35 pounds heavier and 2 inches taller. The 1011200N42 is cross-linked polyethylene for oxidizers. The WB21 is the black water tank in this same doorway shape, for stored water rather than chemical, and the 1008200C26 lays 330 gallons down to 50 inches on a 47 inch base.

Connections

• Access: 18 inch threaded, vented manway; fill by hose or tote pump down a dip tube, and vent to the outside if the liquid fumes.
• Outlet: name the liquid when ordering so the bulkhead fitting matches it; run a flexible line to the pump suction and hang the valve off the floor, not the tank.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white 80 inch tank shows its level in daylight; a float switch for low level protects a pump. Put the dosing pump below the outlet, where it primes by gravity, close the manway against vapor loss, and keep a light-sensitive chemical out of direct sun. A 35 inch tank fits a standard spill pallet.

What it holds in practice

Treatment chemicals at a small system that needs the certification on file, brine for a softener, 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.

Getting it to the pad

The 1630000N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator turns your ZIP into a freight number; the price on this page is before freight. One person carries 65 pounds through a door. Strap it, water-fill to the manway and hold it, check the outlet fitting, and keep the certification paperwork with the project file. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
