The Enduraplas 5000 Gallon White Cone Bottom Tank with Stand (SKU THC05000KW) is a full-drain vessel built for processes where you need the tank to empty completely - settling, batching, dosing, and dewatering. It stands 175 inches tall on a 110-inch diameter footprint, molded in natural white polyethylene at roughly 1,100 pounds empty, and rides on an integrated stand that holds the cone above grade so gravity does the draining. The tank carries a 1.9 specific gravity rating, ships with a 3" PP female NPT bulkhead outlet at the cone tip and a 16" threaded vented manway up top, and is FDA approved. If you are cross-shopping, the common search language here is 5000 gallon cone bottom, Enduraplas white cone, and 5000 gallon tank with stand.
Will it hold what you are putting in it
Start with weight, because a cone-bottom on a stand lives and dies by load math. Filled with water this tank carries about 41,700 pounds; at its full 1.9 SG rating the contents can reach roughly 79,230 pounds. That 1.9 rating is the maximum poly rating we carry - there is no higher-SG tank to step up to - so confirm your product's specific gravity against that ceiling before you buy. Several chemistries below sit at exactly 1.9 required SG, which means zero headroom: a heavier-than-spec batch or a concentrated slurry leaves no margin, and the stand and anchoring have to carry the full load. Use the Tank Sizing Calculator and the Tank Sizing Guide to check your fill weight against the rating, and see the technical drawing on this page for the fitting locations and overall geometry.
Chemical compatibility
This tank is molded in polyethylene rated to 1.9 specific gravity, but the resin type is unconfirmed - HDLPE versus XLPE - so confirm which with us before committing it to chemical service, since crosslinked and linear polyethylene behave differently against some chemistries. The chemicals below are drawn from the Snyder Industries OEM chemical resistance chart; every entry is concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and the fitting and gasket materials before ordering.
Representative compatible chemistries include Sulfuric Acid at 98% (CPVC fittings, Viton gaskets), Hydrochloric Acid at 37% (PVC, Viton), Sodium Hypochlorite below 16.5% (PVC, Viton), Ferric Chloride at 50% (PVC, EPDM), Phosphoric Acid at 85% (PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Peracetic Acid at 30% (316SS, Aflas), Aluminum Sulfate at 50% (PVC, EPDM), and Calcium Chloride at 40% (PVC, EPDM). Lower-SG products such as DEF at 32.5% (316SS fittings, EPDM gaskets) and Urea Solution at 50% (PP/PVC fittings, EPDM gaskets) both carry a 1.35 required SG and sit well within this tank's 1.9 rating.
The single most likely field failure here is the outlet. The stock 3" bulkhead is PP (polypropylene), and the flagship acids above require non-PP wetted parts: Sulfuric 98% needs CPVC, Hydrochloric 37%, Phosphoric 85%, Hydrogen Peroxide 50% and Sodium Hypochlorite need PVC with Viton, and Peracetic 30% needs 316SS with Aflas - not EPDM. Plan to swap the PP stock outlet for the correct fitting and gasket for your service. Full pairings live in our Chemical Compatibility Database.
