Snyder Industries 90 Gallon HDLPE Chemical Feed Station Tank with Stand in White

The 90 Gallon HDLPE Chemical Feed Station Tank with Stand (SKU SII-5690104CFWS45) is a Snyder Industries specialty tank built for point-of-use chemical dosing where you need the tank elevated on its own integrated stand. Molded from high density linear polyethylene in white, it carries a 1.9 specific gravity rating - meaning the tank wall is engineered for heavy chemistries, not just water - and stands 57 inches tall on a 43 x 56 inch footprint. The empty tank weighs 123 pounds, the 14-inch lid gives you top access for fill, vent, and level instrumentation, and it carries Snyder standards 2285 and 2282. Its rated temperature ceiling is 120 F / 48 C.

Will it work for your chemical feed setup?

This is a 90 gallon feed-station tank, so size the duty around what it actually holds. Filled with water the tank and contents run about 751 pounds; at its 1.9 SG rating the maximum rated contents weight is 1,426 pounds. The stand and pad are the anchoring point here - engineer them for that 1,426 lb max rated load, not the 751 lb water figure buyers default to, and plan any secondary containment under the stand for the same load path. If you are unsure the 90 gallon working volume matches your dosing cycle, run your feed rate and refill interval through the Tank Sizing Calculator and the Tank Sizing Guide. Because this is a chemical feed station, plan your top penetrations before you drill: our guide on top fitting placement strategy and level gauge selection will save you a reconfiguration later. See the technical drawing on this page for the dimensioned layout.

Chemical compatibility

This tank is HDLPE with a 1.9 SG rating, sourced against the Snyder Industries OEM chemical resistance chart. Compatibility is always concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and fitting plus gasket materials before service. Chemistries this tank supports (with the fitting and gasket materials that pair to them) include sulfuric acid at 98% (CPVC fittings, Viton gaskets), hydrochloric acid at 37% (PVC, Viton), phosphoric acid at 85% (PVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), hydrogen peroxide at 50% (PVC, Viton), sodium hypochlorite under 16.5% (PVC, Viton), peracetic acid at 30% (316SS fittings, Aflas gaskets), ferric chloride and ferric sulfate (PVC, EPDM), potassium hydroxide saturated (PVC, EPDM), ethylene glycol at 100% (PVC, EPDM), and zinc orthophosphate (PP/316SS, EPDM). Lower-SG chemistries such as acetic acid at 60%, aluminum sulfate, calcium chloride, magnesium chloride, sodium carbonate, ferrous sulfate, DEF at 32.5% (316SS fittings), urea solution, and ozonated water are also on the chart. A materials warning that catches people out: oxidizer and high-purity lines - peracetic acid, DEF, propylene glycol, and zinc orthophosphate - need 316SS or PP fittings, not the PVC most feed lines default to. Match each chemical to its specific fitting and gasket and verify against the concentration/temperature-specific OEM chart. Full detail for each chemistry is on our Chemical Compatibility Database - for example sodium hypochlorite, sulfuric acid, ferric chloride, hydrochloric acid, and DEF. If you sample the dosing line, follow our chemical sampling protocol so your lab results match what is actually in the tank.

The mistake to avoid

Do not assume every gasket is fine because the tank wall is rated 1.9 SG. The tank body and the elastomer at each fitting are two separate decisions - sodium hypochlorite, sulfuric acid, and hydrogen peroxide all need Viton (or Aflas for peracetic acid), while most salts and glycols run EPDM. Putting an EPDM gasket on a strong-oxidizer line is the failure that shows up as a leak, not a warning. Note too that sodium hypochlorite, hydrogen peroxide, and sulfuric acid all sit at required SG 1.9 - they consume the full rating with zero derating headroom, so hold temperature under the 120 F / 48 C ceiling and confirm concentration tightly for those lines. The good news on the flip side: no chemistry on the Snyder chart for this service exceeds the tank's 1.9 SG rating, so no heavier-wall upgrade is required for any of the listed chemicals. When you handle these chemistries, label the tank correctly too; our guide on NFPA 704 and GHS labeling covers the placarding that inspectors check.
