The Snyder Industries 275 Gallon Plastic Chemical Feed Station Tank is purpose-built for the dosing room: a 275-gallon white HDLPE vessel molded to a 1.9 specific-gravity rating, standing 59 inches tall on a 62 by 76 inch footprint. The heavier 1.9 SG rating is the headline number for a chemical feed station, because most concentrated treatment chemicals weigh more than water and the resin has to carry that load for years. Filled with plain water this tank holds roughly 2,294 pounds; filled to its maximum rated contents weight it is engineered to support up to 4,358 pounds, so you size your slab, saddle, and anchoring to that upper figure, not the water number.
Will this Snyder chemical tank work for your application?
Confirm three things before you commit it to service. First, capacity and fit: 275 gallons inside a 62 by 76 inch footprint and a 59 inch height, which is the dimension that decides whether it clears a roll-up door or fits under a low ceiling alongside your feed pump skid. Second, weight: design the floor and any restraint for the 4,358 pound max-rated load, because a feed station that sloshes or vibrates against an undersized stand is the most common mistake we see. Third, the chemical itself against the 1.9 SG rating and the HDLPE resin. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the gallons you actually need for your dosing interval, and review the technical drawing on this page for the molded-in details.
Chemical compatibility
This tank is molded from high density linear polyethylene (HDLPE) and carries a 1.9 specific-gravity rating, which is why it is rated for the dense, concentrated chemistries common to water and wastewater feed stations. Always confirm the chemical against its concentration and temperature using the OEM chemical-resistance chart and our Chemical Compatibility Database before service, since compatibility is concentration- and temperature-specific. Documented compatible chemistries for this resin and SG rating include sodium hypochlorite (<16.5%, PVC fittings, Viton gaskets), sulfuric acid (98%, CPVC fittings, Viton), hydrochloric acid (37%, PVC, Viton), phosphoric acid (85%, PVC, Viton), ferric chloride (50%, PVC, EPDM), aluminum sulfate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), hydrogen peroxide (50%, PVC, Viton), peracetic acid (30%, 316SS, Aflas), hydrofluoric acid (48%, PP/PVC, Viton), DEF (32.5%, 316SS, EPDM), urea solution (50%, PP/PVC, EPDM), ethylene glycol (100%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), ferric sulfate (60%), sodium carbonate (30%), polyaluminum chloride, zinc orthophosphate, and ozonated water (up to 10 PPM, PVC fittings, EPDM gaskets), among others. Fitting and gasket material matters as much as the tank wall: most acids and salts run PVC fittings with EPDM, chlorine and oxidizer service want Viton gaskets, and the most aggressive oxidizers move you off plastic entirely — peracetic acid, for instance, requires 316SS fittings with Aflas seals. A short list of chemistries run on stainless rather than plastic fittings: DEF and peracetic acid both spec 316SS, as do propylene glycol and zinc orthophosphate (PP/316SS). Choosing an EPDM gasket on a sodium hypochlorite line is the kind of detail-level mistake that fails before the tank ever does.
Freight and ordering
This Snyder Industries chemical tank ships LTL from the manufacturing plant in Marked Tree, AR, with freight quoted live to your ZIP code rather than rolled into the list price. Get an exact number through the Freight Cost Estimator, or call 866-418-1777 to talk through plumbing your feed station. Before you finalize the build, a few resources worth reading: our guide on tank level gauge selection for chemical service for picking the right level technology, the Snyder Captor 110% containment vs UL-142 / SPCC comparison for speccing secondary containment on a concentrated-chemical feed station, the chemical sampling protocol for keeping dose accuracy honest as stored chemicals stratify, and tank label and signage compliance for getting the hazard placarding right the first time.
