Snyder Industries 35 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Small tank, plant-grade wall

A 35 gallon tank is the day tank on a pilot plant, the make-up tank on a lab skid, or the reservoir on a chemical feed cart, and at 36 inches on a 22 inch base it is bracketed to something. What it shares with the largest tanks in the same line is the wall, sized for a liquid nearly twice as dense as water under ASTM D1998; the HDPE tank wall thickness guide explains that logic and why the vapor headspace is where a wall fails first, at any size, and the freeboard sizing guide works out how much of the nominal 35 gallons is usable once thermal expansion is accounted for. Full, it puts 555 pounds on a 22 inch circle, which a bench or a paver supports; 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; at this size the reserve is measured in hours, and the tank is refilled from a carboy.

Snyder's smallest verticals

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 1541000N51 is the squat 30, 13 inches shorter on a base an inch wider, for a bench without a bracket, and the 1540700N51 holds 50 gallons 2 inches taller.

Need the taller or the wider one? Every row links to its page with freight to your ZIP on each; 866-418-1777 will check the ceiling and the pad.

Access and outlet

• Access: 6 inch threaded lid; filled by funnel or drum pump from a carboy.
• Outlet: the bulkhead fitting is chosen for the chemical at order time; a flexible line to the pump suction.
• Service limit: 120 F / 48 C.

A tank this small stands on a bench or a spill tray, bracketed so a snagged hose cannot drag it, with the dosing pump below the outlet so it primes by gravity. A white 36 inch tank shows its level at a glance; a low-level float switch protects the pump. Close the lid to stop vapor loss, and keep a light-sensitive chemical out of direct sun.

Put to use

Pilot plants, lab skids, chemical feed carts, small package treatment plants, and the bench reservoir that feeds a metering pump for a test. One chemical per tank, labeled, refilled on a schedule the chemistry tolerates, and rinsed at every changeover, which takes a minute.

How it ships

At 18 pounds and 22 by 22 by 36 inches, the 1000110N45 ships by UPS rather than freight; the freight cost estimator shows the cost to your ZIP, and the listed price is before shipping. Unbox it, check the lid and the outlet fitting, and fill it once with water to prove the seal before the first chemical goes in. A strap that is checked once a season is a strap that holds; put it on the same calendar as the gutters.
