The Snyder Industries 250 Gallon Plastic Chemical Feed Station Tank (SKU SII-5730103CF45) is molded from high density linear polyethylene (HDLPE) and carries a 1.9 specific gravity rating. That 1.9 rating is the sizing number that matters: filled with plain water this 250 gallon tank carries about 2,085 lb, but loaded to its full 1.9 SG rating the contents can reach roughly 3,962 lb, so build the pad, ring, or saddle for the heavier figure. At 1.9 SG this is Snyder's high-gravity chemical wall; if your liquid exceeds 1.9 SG, polyethylene is out of envelope. The tank stands 69 inches tall on a 62 x 76 inch footprint, holds 250 gallons, and is white.
Will it work for your application
Size the foundation and clearances to the loaded 3,962 lb figure rather than the 2,085 lb water weight whenever you are storing concentrated chemicals. The 62 x 76 inch footprint and 69 inch height set your clearance under fill lines and feed pumps, and the technical drawing on this page shows the molded port layout. To match gallons and fluid weight to your duty cycle, run the Tank Sizing Calculator or read the Tank Sizing Guide. This is a 250 gallon chemical tank built for metering and feed-station duty, not a general water tank.
Chemical compatibility
This tank has an HDLPE wall rated to 1.9 SG. If your chemistry or specific gravity demands a cross-linked (XLPE) wall, this is not the right tank, so settle resin choice before you order. Compatibility also depends on the fitting and gasket materials you pair with it, and every pairing below is concentration- and temperature-specific. Always verify each chemical against the OEM chemical-resistance chart at your exact operating concentration and temperature.
| Chemical | Conc. | Fitting | Gasket |
|---|---|---|---|
| Acetic Acid | 60% | PP/PVC | EPDM |
| 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 |
| Polyaluminum Chloride | verify | PVC | EPDM |
| Potassium Carbonate | 50% | PVC | EPDM |
| Potassium Hydroxide | Saturated | PVC | EPDM |
| Propylene Glycol | verify | PP/316SS | EPDM |
| Sodium Bisulfate | verify | PVC/PP | EPDM |
| Sodium Bisulfite | verify | PVC/PP | EPDM |
| Sodium Carbonate | 30% | PVC | EPDM |
| Sodium Hypochlorite | <16.5% | PVC | Viton |
| Sodium Thiosulfate | 40% | PVC | EPDM |
| Sulfuric Acid | 98% | CPVC | Viton |
| Urea Solution | 50% | PP/PVC | EPDM |
| Zinc Orthophosphate | verify | PP/316SS | EPDM |
| Ozonated Water | up to 10 PPM | PVC | EPDM |
Watch how the gasket call-out shifts by chemistry: sodium hypochlorite, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, phosphoric acid and sulfuric acid all want Viton over EPDM, and peracetic acid jumps to Aflas with 316SS hardware. Matching the gasket to the chemical is the single most common mistake on a chemical feed install. Entries marked "verify" are concentration-dependent in the chart, so confirm your strength before you spec hardware. Start at our Chemical Compatibility Database and confirm each chemical at your operating conditions.
The mistake to avoid
The trap with a 1.9 SG feed-station tank is treating gravity and gasket selection as afterthoughts. Size the foundation to the loaded 3,962 lb figure, not the 2,085 lb water weight, and match every flange gasket to the chemical rather than to whatever is on the shelf. Before commissioning, settle level instrumentation, labeling, and sampling cadence: see level gauge selection for chemical service, tank label and signage compliance, the chemical sampling protocol, and if you are weighing secondary containment, the Snyder Captor Plus 110% containment comparison.
