8000 Gallon 15 Degree Plastic Cone Bottom Tank with Stand

The Enduraplas 8000 Gallon 15 Degree Plastic Cone Bottom Tank with Stand is built for high-volume batching, mixing, and full-drain process work where you need every gallon to move toward the outlet. The 15-degree cone floor slopes product to the center discharge so solids and slurries clear instead of settling, and the integrated stand holds the cone off the ground so you can plumb a valve and drain by gravity. At 8,000 gallons this is a large-capacity cone-bottom vessel, and the verified footprint and fill weight below tell you exactly what your pad and plumbing have to carry.

Confirm before you order for chemical service: this configuration does not carry a published specific-gravity rating. Do NOT order it for any fluid heavier than water (SG 1.0) until we confirm the resin and its SG rating by phone. If your chemical's weight-per-gallon exceeds the confirmed rating, this specific unit is not the tank for it — call 866-418-1777 and we will spec the right vessel.

Will it work for your process?

Verified dimensions are a 144 in x 144 in square footprint with 158 in overall height (dims verified), rated at 8,000-gallon working capacity. The stand-mounted 15-degree cone is the geometry you want for consistent full-drain service, versus a flat-bottom or a shallower slope that leaves a heel behind. Because this is a chemical-service vessel, match the resin to your fluid before you commit — the single most load-bearing number is the specific gravity of what you are storing. Water at SG 1.0 is your baseline; anything heavier must be verified against the tank's rating first. Our Tank Sizing Calculator and Tank Sizing Guide walk through matching volume, weight, and layout to your application, and searches for a poly cone bottom tank with stand land here for exactly this full-drain configuration.

Chemical compatibility

For a cone-bottom chem tank, the elastomer at the outlet matters as much as the tank wall. Confirm compatibility of your chemical against BOTH the tank resin AND the bulkhead-fitting gasket material before ordering — check both in our Chemical Compatibility Database, which is concentration- and temperature-specific. Outlet size and fitting configuration are confirmed per order on a tank this size, so call 866-418-1777 to spec your bulkhead fitting and gasket for chemical service rather than assuming a standard layout.

Weight and freight planning

Filled with water at SG 1.0, this tank carries roughly 66,720 lb — over 33 tons — across that 144 x 144 in footprint. That load dictates a reinforced concrete pad and a level, engineered base; a stand-mounted cone concentrates weight and cannot sit on soil or asphalt. Plan your discharge plumbing and containment before the tank arrives, and review the technical drawing on this page for the stand height and outlet position that set your valve and pump clearances. Our buyer's guides on the 550 gallon 20-degree cone bottom with poly stand and 300 gallon 30-degree cone bottom with poly stand explain how cone angle and stand choice change your drain performance.

A tank this size ships LTL freight as an oversized load, and freight is quoted separately to your ZIP — never rolled into the list price. Get an exact number with our Freight Cost Estimator, or call 866-418-1777 and we will size the truck and offload plan (this class of large cone-bottom tank often needs a flatbed) for your site. Confirm your resin, SG rating, and gasket with our team, get your freight number, and we will help you land this 8,000-gallon cone-bottom tank on a properly engineered pad.
