The Enduraplas 2000 Gallon Green Cone Bottom Tank with Stand is a full-drain vessel built for batching, mixing, and chemical storage where the tank has to empty completely. Molded from polyethylene with a 1.9 specific gravity rating, it stands 113 inches tall on a 90-inch-diameter footprint, carries a 3" PP female NPT bulkhead fitting at the cone tip, and takes a 16" threaded vented manway up top. The empty tank weighs 500 lb and is FDA approved. The cone-and-stand design lets gravity pull solids and sediment to the outlet, so you drain and clean without a residual heel sitting in a flat bottom.
Will it handle your load?
The 1.9 SG rating is the number that matters. Filled with water, contents weigh about 16,680 lb; at the full 1.9 specific gravity the tank is rated to carry up to roughly 31,692 lb of contents. That headroom is what qualifies this tank for dense chemistries, not just water. It is also the point worth being clear on: 1.9 SG is the top build of this tank — there is no denser-rated version to step up to, so spec confidence comes from confirming resin and wetted parts, not from a bigger tank. Because it is a cone on a steel stand, that whole load is elevated — figure roughly 32,000 lb of tank plus contents landing on a 90-inch-diameter footprint, and size your slab and anchoring to that loaded elevated figure, not to the water weight. If you are still matching gallons to your process volume, run the numbers through our Tank Sizing Calculator and cross-check the Tank Sizing Guide before you commit. See the technical drawing on this page for the full dimensional layout of the tank and stand.
Chemical compatibility
This tank carries a 1.9 SG rating, and its resin is high-density polyethylene pending confirmation — before any chemical service, confirm HDLPE vs XLPE with us, because that single answer decides your entire fitting and gasket spec. The compatibility data below is cross-referenced from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and the actual Enduraplas resin for this SKU before you order fittings.
Chemistries this tank's 1.9 SG rating supports at the listed concentrations include hydrochloric acid (37%), sulfuric acid (98%), phosphoric acid (85%), hydrofluoric acid (48%), hydrogen peroxide (50%), sodium hypochlorite (under 16.5%), ferric chloride (50%), ferric sulfate (60%), ethylene glycol (100%), peracetic acid (30%), potassium hydroxide (saturated), and potassium carbonate (50%). Match the fitting material (PVC, CPVC, PP, or 316SS) and gasket (EPDM, Viton, or Aflas) to each chemical — the wrong gasket fails long before the tank does. Full detail lives in our Chemical Compatibility Database.
The mistake to avoid: the stock outlet is not the right outlet for every chemistry
The tank ships with a 3" PP female NPT bulkhead as the default outlet, and many of the chemistries above need different wetted parts than that default. A few examples straight from the resistance chart:
- Sulfuric acid 98% — CPVC fitting, Viton gasket
- Sodium hypochlorite <16.5% — PVC fitting, Viton gasket
- Hydrochloric acid 37% — PVC fitting, Viton gasket
- DEF 32.5% — 316SS fitting, EPDM gasket
Lower-SG chemistries each carry their own spec as well: DEF (32.5%) calls for 316SS, while urea solution (50%) runs on PP or PVC with EPDM. Do not spec this tank to its 1.9 ceiling without confirming resin and fittings first. And because this is a cone on a steel stand, the stand carries the whole load — read our stand selection decision tree and the stand compatibility matrix so the frame is matched to the tank.
