The Snyder Industries 250 Gallon Plastic Chemical Feed Station Tank is purpose-built for metering and dosing aggressive chemicals, molded from high density linear polyethylene (HDLPE) and rated to a 1.9 specific gravity. At 86 inches tall with a 62 by 76 inch footprint, this white tank holds 250 gallons and gives you the headroom and stability a feed-station layout needs. The 1.9 SG rating is the number that matters most here: it means the tank is engineered to carry chemistries far heavier than water, which is why it surfaces when buyers search for a heavy-duty 250 gallon chemical tank rather than a general-purpose 250 gallon tank. At 1.9 SG this sits at the top of the standard rating tier, well above a 1.5-rated general-purpose 250-gallon tank.
Will it work for your application?
Start with weight, because that drives both your pad and your freight. Filled with water this tank carries roughly 2,085 lb; loaded to its maximum rated contents at the 1.9 SG limit it can reach about 3,962 lb. Size your concrete pad, secondary containment, and anchoring to the heavier figure, not the water number, since chemical feed stations rarely run plain water. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 250 gallon working volume and the 62.0 x 76.0 footprint fit your dosing skid before you commit. The molded outlet and fitting configuration are shown on the technical drawing on this page; reference it for fitting locations and exact dimensions rather than assuming an outlet size. Because chemical level drives your dosing accuracy, pair the tank with the right instrumentation - our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options for this kind of duty.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, which covers the full slate of common water-treatment and feed-station chemistries below. Compatibility always depends on concentration and temperature, so verify every chemistry against the OEM chemical-resistance chart at your specific concentration and operating temperature before service. The single most common mistake on a feed station is matching wetted parts to the tank instead of to the chemistry: EPDM is the default gasket for most of these chemistries, but the strong oxidizers and acids do not tolerate it. Specify Viton gaskets for hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, and sulfuric acids plus hydrogen peroxide and sodium hypochlorite, and Aflas for peracetic acid. On the fitting side, most chemistries run PVC or CPVC, but four require stainless: DEF, peracetic acid, propylene glycol, and zinc orthophosphate all call for 316SS (or PP/316SS) wetted parts. DEF in particular (the 32.5% urea solution that also appears below as a 50% urea solution) demands clean, dedicated 316SS fittings - PVC and any cross-contamination will spoil the fluid.
The fitting and gasket materials listed are the recommended wetted materials for each chemistry:
- 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
Build the wrong fitting train and the tank will outlast hardware that fails in weeks. See the full Chemical Compatibility Database for concentration and temperature detail on each chemistry.
