15 Gallon HDLPE Cone Bottom Tank with Sump

The 15 Gallon HDLPE Cone Bottom Tank with Sump from Snyder Industries is a compact full-drain vessel built for chemical metering and batch work where you cannot afford a heel of product sitting in a flat bottom. Standing 36 inches tall on a 17 x 17 inch footprint and holding 15 gallons, this white polyethylene cone tank carries a 1.9 specific gravity rating - the high-density mark that tells you it is engineered for heavier-than-water chemistry, not just water transfer. The cone bottom feeds a sump so the tank empties cleanly between batches, which is why operators reach for a cone tank over a standard vertical when dosing or recirculating concentrated solutions.

Will it work for your application

Filled with water this tank weighs about 125 lbs, and at its maximum rated contents it carries up to 238 lbs - the gap between those two numbers is what the 1.9 SG rating buys you, the headroom to store fluids denser than water without overstressing the wall. The 17 x 17 inch footprint and 36 inch height make it a benchtop or stand-mounted unit; cone-bottom tanks of this style require a stand or support structure to hold the cone clear of the floor. Size that stand, saddle, and any strapping for the full 238 lb loaded weight, not the 125 lb water figure - defaulting to the water weight is how a frame gets under-built. To match capacity against your batch volume and dose rate, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.

Fittings and sump outlet

Our catalog record for this SKU has no confirmed factory fitting, top-port, or sump-outlet sizes, and there is no technical drawing on file for it here. If you are plumbing a metering skid or a recirculation loop, do not assume an outlet thread - call 866-418-1777 to confirm the sump outlet size and top-fitting configuration before you order hardware. Our guide on top fitting placement walks through laying out vent, fill, level, and drain so you avoid cross-contamination and maintenance conflicts.

Chemical compatibility

This is a high-density linear polyethylene tank with a 1.9 specific gravity rating. The resin family on the catalog record is marked HDLPE? - confirm HDLPE versus XLPE (crosslinked) with us before committing the tank to chemical service, because the two resins behave differently against certain oxidizers and solvents. The compatibility below comes from the OEM chemical-resistance chart and is concentration- and temperature-specific; verify your exact concentration and operating temperature against the chart before ordering, and match the listed fitting and gasket materials.

The 1.9 SG rating and HDLPE wall support storage of, among others: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), and Urea Solution (50%, PP/PVC, EPDM). Notice the gasket swing between EPDM and Viton, and the jump to 316SS or CPVC fittings on DEF, peracetic acid, and concentrated sulfuric - matching the wrong elastomer to the wrong chemistry is the most common metering-skid failure. Cross-check every selection in our Chemical Compatibility Database.

Several chart entries are listed compatible but did not carry a specified concentration: Polyaluminum Chloride (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), and Zinc Orthophosphate (PP/316SS, EPDM). Treat these as concentration-unspecified and confirm your exact strength against the chart before you commit. Ozonated Water (up to 10 PPM, PVC, EPDM) is also listed compatible but has no dedicated compatibility page here and is an oxidizer service item - confirm it with us directly, in line with the HDLPE-versus-XLPE oxidizer caution above.

The mistake to avoid

The error on a cone tank like this is treating it as a generic 15-gallon drum. Two things bite. First, the resin question - do not assume crosslinked; confirm the HDLPE versus XLPE record with us for your chemical, since SG-1.9 HDLPE is the right wall for these dense solutions but the resin chemistry still governs oxidizer service. Second, the fittings are not one-size: a feed line for sodium hypochlorite wants PVC and Viton, while DEF and peracetic acid call for 316SS - and because we have no factory port data on file, get the sump outlet and top layout confirmed by phone before you plumb it. Our guides on level gauge selection, hazard labeling, and loadout pad and containment design walk through getting these decisions right the first time.
