125 Gallon 15 Degree Cone Bottom Tank with Poly Stand

The Norwesco 125 Gallon 15 Degree Cone Bottom Tank with Poly Stand (SKU N-43161) is built for batch mixing and full-drain chemical handling where you need gravity to empty the vessel completely.It holds 125 gallons in a white FDA-approved polyethylene tank rated to a 1.5 specific gravity, sits on a matching poly stand at 48" diameter and 41" tall, and empties through a 15-degree cone into a 2" fitting with a 2" siphon.Fill and vent from the 8" lid on top.Empty tank weight is 87 lb.

Will it work for your process?

The 1.5 specific gravity rating is the number that decides fit.Water-weight full, this 125 gallon tank carries about 1,042 lb; loaded to its full rated density it can hold up to roughly 1,564 lb of contents.Size your pad and any anchoring to that 1,564 lb loaded figure - not the 87 lb shipping weight - because the cone geometry puts the entire load onto the stand's 48" diameter footprint.Maximum service temperature is 120 F (48 C); keep sustained contents below that.The 2" outlet with siphon pulls from the very bottom of the cone for near-complete drainage on each batch.Run your working volume and weights through the Tank Sizing Calculator and Tank Sizing Guide before you buy, and see the technical drawing on this page for exact port placement.

Chemical compatibility

This is a polyethylene tank rated to 1.5 specific gravity.The resin is listed as HDLPE but not fully confirmed - confirm HDLPE versus XLPE before putting any chemical in service, since crosslinked and linear polyethylene handle some chemistries differently.Compatibility below is drawn from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific; verify your exact chemical, concentration, temperature, and fitting plus gasket materials before ordering.

Chemicals this 1.5 SG tank handles at the listed concentrations include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC/EPDM), calcium chloride (40%, PVC/EPDM), ferrous sulfate (20%, PVC/EPDM), magnesium chloride (30%, PVC/EPDM), sodium carbonate (30%, PVC/EPDM), and ozonated water in oxidizer service up to 10 PPM (PVC/EPDM) - note the 10 PPM ceiling, this is not for unlimited ozone exposure.For DEF (32.5%, 316SS/EPDM) and urea solution (50%, PP/PVC, EPDM), which only call for a 1.5 SG tank, this 1.5-rated tank runs with margin to spare - a comfortable pick for the DEF and ag-urea buyer.Match the fitting and gasket material to the chemical; the wrong elastomer fails long before the tank does.Cross-check every choice against our Chemical Compatibility Database.

The mistake to avoid: don't put a heavy chemical in a 1.5 SG tank

Several common chemicals need a heavier-walled, higher specific-gravity tank than this one - do not run them in the 1.5 SG N-43161.Those requiring a 1.5 SG tank include sulfuric acid (98%), hydrochloric acid (37%), phosphoric acid (85%), hydrofluoric acid (48%), ferric chloride (50%), ferric sulfate (60%), sodium hypochlorite (<16.5%), sodium bisulfite, hydrogen peroxide (50%), peracetic acid (30%), ethylene glycol (100%), and potassium hydroxide (saturated), among others.Several of these also demand Viton or Aflas gaskets - and CPVC or 316SS fittings - rather than the EPDM used on the compatible list above, so it is not just wall thickness that changes.If your process uses one of these, spec the higher-SG tank instead; that is the honest fit, and we can point you to it.
