Snyder Industries 30 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Small tank, plant-grade wall

A 30 gallon tank is the day tank on a pilot plant, the make-up tank on a lab skid, the polymer batch for a small package plant, or the reservoir on a chemical feed cart, and a shell as wide as it is tall cannot tip. What it shares with the largest tanks in the same line is the wall, 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, at any size. Full, it puts 475 pounds on a 23 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 N51 is another resin option in the same shell, a pound lighter. The 1530000N45 is the 22 gallon step down, the same 23 inches tall on a base 5 inches narrower at half the weight. The 1000110N42 is the cross-linked 35, 13 inches taller on a base an inch narrower, for oxidizers.

Ports and access

• Access: 10 inch lid; filled by hose or funnel from a carboy.
• Outlet: specify the bulkhead fitting for the chemical when ordering; a flexible line to the pump suction.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

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 23 inch tank shows its level at a glance; a low-level float switch protects the pump. Keep the lid shut so nothing is lost as vapor, and shade the tank if the chemical is light-sensitive.

Typical duty

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.

Freight to your ZIP

At 19 pounds and 23 by 23 by 23 inches, the 1541000N45 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, fill it once with water to prove the seal, and keep the certification paperwork with the project file. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
