The Enduraplas 1100 Gallon White Cone Bottom Tank with Stand (SKU THC01100KW) is a full-drain vessel built for processing and dosing work where you need every gallon to gravity-feed out the bottom. Molded in Natural White polyethylene with a 1.9 specific gravity rating and FDA-approved, this 1100 gallon tank stands 113 inches tall on a 60-inch diameter footprint and ships with its supporting stand. The empty tank weighs 440 pounds, and the cone-and-stand design keeps the outlet elevated so you can pipe straight into a pump or drain line.
Will it work for your application?
The 1.9 SG rating is the number that matters most here. It tells you the walls are engineered to hold contents up to 1.9 times the weight of water. Filled with water, the load is 9,174 pounds; at the full 1.9 rating the tank is built to carry up to 17,431 pounds of contents. That headroom is why this white cone bottom tank suits heavier chemical duty, not just water storage. As supplied, the fittings are a 3" PP Female NPT bulkhead outlet at the cone tip and a 16" threaded vented manway on top for filling and inspection. The vented manway matters: gravity draw and pump feed both need air to replace the volume leaving the tank. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 1100-gallon working volume and the filled weight your stand pad and floor must carry, and see the technical drawing on this page for the cone and stand geometry.
Chemical compatibility
This tank is polyethylene rated to 1.9 specific gravity, checked against the Snyder Industries OEM chemical resistance chart. The resin is listed as HDLPE with a question mark, so before you commit to any chemical service, confirm whether your tank is HDLPE or XLPE and match your exact chemical, concentration, and temperature. Chemicals the chart supports at this tank's 1.9 SG include Ethylene Glycol (100%, PVC fittings, EPDM gaskets), Ferric Chloride (50%, PVC/EPDM), Ferric Sulfate (60%, PVC/EPDM), Hydrochloric Acid (37%, PVC fittings with Viton gaskets), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC/Viton), Phosphoric Acid (85%, PVC/Viton), Potassium Hydroxide (saturated, PVC/EPDM), Sodium Hypochlorite (under 16.5%, PVC/Viton), Sulfuric Acid (98%, CPVC fittings with Viton gaskets), and Peracetic Acid (30%, 316SS fittings with Aflas gaskets). Lower-SG-rated fluids are within capability too, since 1.9 exceeds their requirement, but they still carry specific fitting and gasket calls: DEF (32.5%, 316SS fittings, EPDM), Urea Solution (50%, PP/PVC, EPDM), Acetic Acid (60%, PP/PVC, EPDM), and Calcium Chloride (40%, PVC/EPDM). The chart is concentration and temperature specific, so verify fitting and gasket material for your exact fluid in our Chemical Compatibility Database before ordering.
The mistake to avoid
Do not assume one gasket material covers every fluid. Several chemicals on the chart require Viton (hydrochloric, sulfuric, hydrogen peroxide, sodium hypochlorite) or specialty elastomers like Aflas (peracetic acid) rather than EPDM, and some demand metal or CPVC fittings rather than PVC: peracetic acid and DEF call for 316SS, and 98% sulfuric acid calls for CPVC. Confirm the gasket material on the supplied bulkhead and match it to your fluid, not to the fitting. And because the resin carries a "?", confirm HDLPE versus XLPE for aggressive service before you fill.
