1600 Gallon 30 Degree HDPE Cone Bottom Tank with Poly Stand in White

The Enduraplas 1600 Gallon 30 Degree Cone Bottom Tank with Poly Stand (SKU 40815) is a white HDPE tank built for full-drain batching, mixing, and dosing where the vessel has to empty completely through the bottom. The 30-degree cone lets solids and slurries slide toward the outlet instead of settling on a flat floor, and the integrated poly stand raises the outlet so you can gravity-feed a pump, valve, or transfer line underneath. One caution up front: this listing does not publish a specific gravity rating, so before you run any chemical or heavy liquid, confirm the SG rating and resin grade with our team for your exact product. This page covers what it holds, how it ships, and that specification to lock down before you put chemistry in it.

Does it fit your process?

Size the pad from these numbers at a glance: 1600 gallons, 96 inches tall, an 89 x 89 inch footprint, and about 13,344 pounds full of water. A heavier product raises that loaded weight in direct proportion to specific gravity, so the concrete or compacted base under the poly stand has to carry the full weight without shifting. Because the cone drains to a single low point, this geometry suits day tanks, blending, and metering setups better than a flat-bottom vertical tank where product would pool. Verified dimensions and the cone angle are shown on the technical drawing on this page — use it to confirm outlet height against your pump inlet. Our Tank Sizing Calculator and Tank Sizing Guide help you match capacity and footprint to your throughput, and the full 1600 Gallon Cone Bottom Buyer's Guide walks through stand and plumbing considerations.

The mistake to avoid: confirm the specific gravity rating

Cone bottom tanks are rated for a maximum contents specific gravity, and that rating is the single most common thing buyers overlook. Because this listing does not publish an SG rating, do not commit the tank to any chemical or heavy-liquid service until you confirm the rating and resin grade for your product. Running a fluid heavier than the tank is rated for stresses the cone and the stand connection over time. When you know your chemical, check it against our Chemical Compatibility Database so the HDPE body, gaskets, and fitting materials are all matched to the concentration and temperature you'll actually run. Do not assume compatibility from the tank material alone — the fittings and gaskets have their own limits.

Freight and how to order

This 1600 gallon cone bottom tank ships by LTL freight on its own pallet or skid, and because it is an oversized poly vessel, freight is quoted separately from the list price and priced to your delivery ZIP. Run your ZIP through our Freight Cost Estimator for a live LTL quote, and note whether you have a forklift or dock, since these tanks often need a liftgate or special unloading on a residential or field site. For help confirming the specific gravity rating, outlet configuration, or delivery logistics for SKU 40815, call One Source Plastics at 866-418-1777 and we'll spec it to your process before it leaves the plant.
