The Snyder Industries 2500 Gallon 30 Degree Plastic Cone Bottom Tank (SKU SII-5110000N45) is built for full-drain chemical and process service where you need the contents to empty completely and leave no settled solids behind. Molded in white polyethylene with a 1.9 specific gravity rating, this 2500-gallon cone bottom tank ships from Lincoln, NE, stands 125 inches tall, and sits on a 90 x 90 inch footprint. The 30-degree cone, fittings, and access points are documented on the technical drawing on this page.
Will this cone tank work for your application?
The 1.9 specific gravity rating is the number that matters most here. At that rating, the tank is engineered to hold contents up to 1.9 times the weight of water, which is why the maximum rated contents weight reaches 39,615 lb even though a full load of plain water weighs 20,850 lb. That headroom is what lets you run dense liquids in this tank rather than topping out at water weight. Factory fittings on this unit include a flange outlet, an 18-inch PE threaded and vented lid, and a manway with 15-inch access. That 15-inch cleanout opening is the figure to note if you run slurry or settling work: a 30-degree cone sheds solids faster and more completely than a shallow cone, but you still want to physically reach inside to clear any residue, and the 15-inch access lets you do it. If you are sizing across cone angles, the Tank Sizing Calculator and Tank Sizing Guide walk through capacity and footprint, and our 2500 Gallon 30 Degree Cone Bottom Tank buyer's guide compares this geometry against the 15-degree version; the 15 vs 30 vs 45 degree selection guide explains when the steeper cone earns its keep. One planning note: at 125 inches (about 10.4 ft) of tank height plus the cone stand underneath, this needs real overhead clearance. Confirm your door, ceiling, or roof-line clearance against the 125-inch tank height plus your stand height before ordering.
Chemical compatibility
This is a polyethylene tank rated at 1.9 specific gravity. Snyder molds cone tanks in both HDLPE and cross-linked (XLPE) resin, and the two carry different chemical-resistance envelopes. Our data records the resin on this unit as HDLPE with a question mark, so resin confirmation is a required pre-order step for any aggressive-oxidizer or strong-acid service - call 866-418-1777 and verify HDLPE vs XLPE before you select from the Viton, CPVC, or 316SS chemicals below. The 1.9 rating gives you genuine density headroom: it clears even the densest listed services, such as 98% sulfuric acid and 85% phosphoric acid, both of which sit near or above water-weight density and would overload a 1.5-rated tank. Fitting and gasket materials below come from the OEM chemical-resistance chart, which is concentration- and temperature-specific - match your actual service conditions to it before ordering hardware.
Chemicals this tank can handle at the listed concentrations, with the recommended fitting and gasket materials:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Notice that aggressive oxidizers and strong acids - sodium hypochlorite, hydrogen peroxide, phosphoric, sulfuric, and the hydrofluoric chemistries - call for Viton or CPVC hardware rather than the standard PVC/EPDM, while DEF and peracetic acid need 316 stainless. Specifying the wrong gasket or fitting material is the most common and most expensive mistake on a chemical cone tank, so cross-check the full Chemical Compatibility Database against your concentration and operating temperature before you order.
Freight and ordering
This is a large cone bottom tank, and a fully loaded unit can carry up to 39,615 lb of dense contents, so the cone stand or support structure has to be rated accordingly. It ships LTL on a freight pallet from the Snyder plant in Lincoln, NE, with freight quoted live to your ZIP - get your number from the Freight Cost Estimator or call 866-418-1777. Confirm the resin type, that the 1.9 specific gravity is correct for your chemistry, and your fitting and gasket materials before you place the order, and our team can help match the hardware to your service conditions.
