The Snyder Industries 550 Gallon HDPE Liquid Storage Tank is a vertical white storage tank molded from high density linear polyethylene at the Snyder plant in Marked Tree, Arkansas. It stands 75 inches tall on a 48 x 48 inch footprint, so it holds 550 gallons while occupying just four feet by four feet of floor space. The tank carries a specific gravity rating of 1.9 and is listed with ASTM certification.
Will this vertical storage tank work for your liquid?
The number that decides whether a vertical tank like this fits your application is the specific gravity rating, and Snyder rates this one to 1.9. That is the density of the heaviest liquid the wall is built to carry. Plain water has a specific gravity of 1.0, so a 1.9 rating leaves a wide margin for water service. In practical terms a 1.9-rated wall on water duty is thicker than a water-only tank of the same size, which means a longer service life on water and headroom if you later move to a denser liquid. Use the two contents weights below to size the pad, the forklift, and the strapping before the tank arrives full.
- Footprint and height: 48 in wide x 48 in long x 75 in tall
- Full of water: about 4,587 lb of contents
- Maximum rated contents (at SG 1.9): up to 8,715 lb
To work backward from how much you need to store to which tank fits, the Tank Sizing Calculator and the Tank Sizing Guide walk through capacity, footprint, and headspace.
The mistake to avoid on an HDPE vertical tank
The trap on a rotomolded HDPE vertical tank is treating the wall as full strength everywhere. The cross-section is thickest at the base, where head pressure is highest, and thinnest at the top near the vapor-saturated headspace, which is exactly where premature wall failures tend to start and where liquid-side inspection misses them. Our guide on HDPE tank wall thickness at the vapor-saturated headspace breaks down the ASTM D1998 sizing logic that operators need to understand. Confirm the fitting layout against the technical drawing on this page, or call us, before you plumb it.
How it ships and what to plan for
This 550 gallon vertical tank ships LTL from the Snyder plant in Marked Tree, AR, with freight quoted live to your ZIP code. Because it is a tall vertical tank, plan a clear delivery spot and someone to receive it. Get a freight quote to your ZIP before you order with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. If you are weighing this 550 against a larger vertical, our 2000 gallon vertical liquid storage tank buyer's guide shows how footprint and height scale up the line.
