The Snyder Industries 90 Gallon Plastic Chemical Feed Station Tank is a compact, day-tank-sized vessel built for metering and feeding chemicals in water-treatment, municipal, and industrial process rooms. It is molded in white High Density Linear Polyethylene (HDLPE) and carries a 1.9 specific gravity rating, so the wall is engineered to hold dense chemical solutions, not just water. At 41 in tall on a 43 x 56 in footprint, it tucks into a feed-station layout while leaving headroom for fill lines, level instrumentation, and a mixer or pump above the lid. It is the right size for a chemical tank that has to live indoors next to the equipment it feeds.
Will this Snyder chemical tank work for your application?
Size your fill by weight, not just gallons. Filled with water this 90-gallon tank carries about 751 lb; at its full 1.9 SG rating the wall is engineered for up to roughly 1,426 lb of contents. The wall itself is rated to that 1.9 SG, so within that envelope the limit you actually have to check is structural: confirm your floor, slab, or skid carries the loaded weight on the 43 x 56 in footprint, and confirm your chemistry stays at or below 1.9 SG (for reference, 98% sulfuric runs near 1.84 and 50% ferric chloride around 1.4 to 1.5, but verify your own product). Use the Tank Sizing Calculator and the Tank Sizing Guide to translate batch volume and chemistry into the right capacity and the loads your structure has to support. Because this is a chemical feed station tank, plan around the instrumentation it will carry and pair it with the right level technology using our guide to tank level gauge selection for chemical service. Fittings and ports are configured per order rather than shipped to a fixed layout, so call 866-418-1777 to spec bulkhead and outlet sizes for your piping, and see the technical drawing on this page for overall dimensions.
Chemical compatibility
This tank is molded in HDLPE with a 1.9 specific gravity rating, which is what qualifies it for the densest chemistries on the list rather than the standard 1.5 SG rating, including Sulfuric Acid 98% and Ferric Chloride 50%. Compatibility depends on the chemical, its concentration, your operating temperature, and the materials you choose for fittings and gaskets, so always verify against the Snyder chemical-resistance chart for your specific concentration and temperature before committing to chemical service. It also covers DEF 32.5% and Urea Solution 50%, both of which call for 316 stainless fittings (with EPDM on DEF) rather than PVC, a genuine spec difference worth confirming up front.
Within this tank's HDLPE / 1.9 SG envelope, commonly stored chemistries and the fitting and gasket materials specified for them include: 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), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate 40% (PVC, EPDM), Sulfuric Acid 98% (CPVC, Viton), Urea Solution 50% (PP/PVC, EPDM), and Zinc Orthophosphate (PP/316SS, EPDM). Match every wetted fitting and gasket to the chemistry, because the wrong gasket elastomer, not the tank wall, is the most common cause of a feed-station leak. The full Chemical Compatibility Database covers each of these with concentration-specific detail.
The mistake to avoid
The trap on a 1.9 SG tank is treating "chemical-rated" as one universal spec. It is not. The HDLPE wall and 1.9 SG rating give you the weight headroom, but your gasket and fitting selection has to follow the chemistry. Note that hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric all call for Viton (with CPVC fittings on sulfuric) while peracetic acid needs Aflas, where the milder salts run EPDM and the DEF and urea streams need 316 stainless. Confirm your exact concentration and temperature against the OEM chart, then specify gaskets and fittings to match. Get the labeling and containment right too: review tank label and signage compliance for bulk polyethylene storage, plan your QA with our chemical sampling protocol, and if you need spill containment compare options in our Snyder Captor Plus 110% containment vs UL-142 / SPCC comparison.
