750 Gallon 20 Degree Cone Bottom Tank with Poly Stand

The Norwesco 750 Gallon 20 Degree Cone Bottom Tank with Poly Stand (SKU N-40809) is a closed-top polyethylene tank built to fully drain by gravity through its 20-degree cone and integrated poly stand.It carries a 1.5 specific gravity rating and FDA Approved polyethylene construction, making it a working choice for metered chemical dosing, batching, and mixing where you need the tank to empty cleanly to the 2" bottom outlet.This Norwesco cone bottom tank stands 67" tall on a 73" diameter footprint, ships empty at 319 lbs, and includes a 16" lid for filling and access.

Will it work for your process?

The elevated poly stand and 20-degree cone let you drain, transfer, or feed downstream equipment without a pump pit.Plan your load around the numbers: filled with water this tank holds roughly 6,255 lbs, and at its full 1.5 SG rating the contents can reach about 9,382 lbs, so the stand pad and floor under the 73" diameter base must be rated for that.The 2" outlet and 16" lid set your plumbing and fill options.Rated maximum operating temperature is 120 F (48 C) - keep the contents below that.Run your volumes through the Tank Sizing Calculator and the Tank Sizing Guide before you commit, and see the technical drawing on this page for the cone geometry and stand dimensions.

Chemical compatibility

Resin grade not yet confirmed - verify HDLPE vs XLPE with us before chemical service, since that difference materially changes compatibility for oxidizers like sodium hypochlorite.This is a polyethylene tank rated to 1.5 specific gravity.Compatibility is always concentration- and temperature-specific per the Snyder Industries OEM chemical resistance chart, so confirm your exact chemical, concentration, temperature, and fitting plus gasket materials.Within its 1.5 SG rating this tank suits Acetic Acid (60%) with PP/PVC fittings and EPDM gaskets, Aluminum Sulfate (50%), Calcium Chloride (40%), Ferrous Sulfate (20%), Magnesium Chloride (30%), and Sodium Carbonate (30%), all with PVC fittings and EPDM gaskets.It also handles DEF (32.5%) with 316SS fittings and EPDM gaskets, Urea Solution (50%) with PP/PVC and EPDM, and Ozonated Water up to 10 PPM with PVC fittings and EPDM gaskets.

The mistake to avoid: specific gravity

The most common and costly error on a chem tank is under-rating specific gravity.This is a 1.5 SG tank, and a number of chemicals need a higher-SG (1.9) tank than this one - do not put them in this 1.5 SG unit.If you are storing Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, or Zinc Orthophosphate, each page states the 1.5 SG requirement.Gasket choice matters too: Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric all require Viton rather than EPDM; Peracetic Acid requires Aflas; and Sulfuric Acid (98%) needs CPVC fittings, not just PVC.Check your chemical in the Chemical Compatibility Database first, and read the 750 Gallon Cone Bottom Complete Buyer's Guide for the full walkthrough.
