The 40 Gallon 40 Degree Cone Bottom Inductor Tank from Norwesco (SKU N-44978) is a 40-gallon white polyethylene cone-bottom inductor built for mixing, batching, and full-drain chemical dosing. The steep 40-degree cone forces complete drainage of slurries and solutions that would settle flat in a conventional tank, and the 2" NPT male thread at the cone tip lets you connect directly to a pump or transfer line. It stands 34" tall on a 27" x 27" footprint, so it drops into tight pump-skid and inductor-stand layouts where floor space is limited. If you are sizing a cone bottom inductor across capacities, this sits in the same line as our 15, 35, 60, and 80 gallon cone bottom inductor tanks.
Will this tank work for your application?
This is a 1.5 specific gravity tank, rated to hold contents up to 1.5 times the weight of water. The math chains directly: 40 gallons of water weighs about 334 lb, and at the 1.5 SG rating the tank is engineered for up to roughly 500 lb of contents (334 lb x 1.5). Before you commit to a chemical, confirm your fluid's specific gravity against that 1.5 rating - overrunning it is the single most common cone-bottom inductor mistake. The only factory fitting is a 2" NPT male thread at the cone apex (see the technical drawing on this page for its exact location), so plan on supplying your own chemical-matched valve, bulkhead, and gasket to complete the plumbing. Run the numbers with our Tank Sizing Calculator and Tank Sizing Guide if you are deciding between this and a larger cone tank.
Chemical compatibility
This tank is white polyethylene at a 1.5 specific gravity rating. Its resin is listed as HDLPE but not confirmed - call us at 866-418-1777 to verify HDLPE versus XLPE before placing it in chemical service, because linear and crosslinked polyethylene resist different chemistries, and that difference matters most with the stronger oxidizers and acids below. A standout fit for this size is diesel exhaust fluid work: the tank is compatible with DEF at 32.5% (316SS fittings, EPDM gaskets, details) and Urea Solution at 50% (PP/PVC fittings, EPDM gaskets, details), making this a ready DEF blending and dosing rig. At the 1.5 SG rating it also handles Acetic Acid (60%, PP/PVC, EPDM, details); Aluminum Sulfate (50%, PVC, EPDM, details); Calcium Chloride (40%, PVC, EPDM, details); Ferrous Sulfate (20%, PVC, EPDM, details); Magnesium Chloride (30%, PVC, EPDM, details); Sodium Carbonate (30%, PVC, EPDM, details); and Ozonated Water (up to 10 PPM, PVC, EPDM). Because the bare tank ships with only the 2" NPT outlet, match every valve, fitting, and gasket to your chemical exactly as listed - for example DEF needs 316SS with EPDM - and always check the OEM chemical-resistance chart for your specific concentration and temperature before filling.
Chemicals that need a higher-SG tank
Several heavier chemicals resist polyethylene but require a 1.9 specific gravity tank rather than this 1.5 SG model - do not run them here. High-demand examples include Sodium Hypochlorite (bleach), Sulfuric Acid, Hydrochloric Acid, and Ferric Chloride, all of which need the heavier-rated cone bottom inductor; the strong oxidizers and acids - Sodium Hypochlorite, Sulfuric Acid, Hydrochloric Acid, Hydrogen Peroxide, and Hydrofluoric Acid - also call for Viton gaskets, and Peracetic Acid needs Aflas. The full 1.9-SG list also includes Ethylene Glycol, Ferric Sulfate, Hydrofluosilicic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Thiosulfate, and Zinc Orthophosphate. If your application is on this list, step up to the 1.9 SG version and review each chemical's requirements in our Chemical Compatibility Database before specifying.
