Snyder Industries 120 Gallon HDLPE Chemical Feed Station Tank with Stand in White

The Snyder Industries 120 Gallon HDLPE Chemical Feed Station Tank (SII-5700104CFWS45) pairs a 120-gallon white high density linear polyethylene tank with an integrated stand, giving day-tank and metering-pump operations a compact, elevated feed point.It carries a 1.9 specific gravity rating, a 14" lid, and a 120 F / 48 C maximum service temperature, and ships empty at 166 lb on a 43" x 56" footprint standing 67" tall.It carries Snyder certifications 2285 and 2282.Because the tank is molded in HDLPE with a heavy 1.9 SG wall, it handles dense chemistries that a standard 1.9 SG water tank cannot — and 1.9 SG is Snyder's top rating for this line, so no heavier shell is needed even for the SG-1.9 acids below.

Will it work for your feed station?

Plan the load before you plumb it.Filled with water the tank and contents run about 1,001 lb; at the full 1.9 SG rating the maximum rated contents weight is 1,902 lb, so confirm your slab, curb, or containment pad and the stand's footing carry the loaded weight at the 43" x 56" footprint.The tank stands 67" tall on its stand, so check overhead clearance for filling and top-fitting access before you site it.Size the volume to your dosing rate and refill interval with the Tank Sizing Calculator and Tank Sizing Guide so the station holds a sensible day's supply without oversizing the stand.When you lay out the top, keep vent, fill, level, and drain penetrations from fighting each other — the fitting placement strategy guide walks the layout, and the level gauge selection guide helps you choose sensing that survives your chemistry.Refer to the technical drawing on this page for the 14" lid position and overall dimensions before ordering accessories.

Chemical compatibility

This tank is molded in HDLPE and rated to 1.9 specific gravity per the Snyder Industries OEM chemical resistance chart.Those ratings are the HDLPE-chart values — the chart also lists XLPE, so confirm you are reading the HDLPE line, not an XLPE datasheet.Compatibility is concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and the fitting and gasket materials before committing.From the OEM chart, this 1.9 SG HDLPE tank suits hydrochloric acid (37%, PVC fittings, Viton gaskets), sulfuric acid (98%, CPVC, Viton), phosphoric acid (85%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), peracetic acid (30%, 316SS, Aflas), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), sodium hypochlorite (<16.5%, PVC, Viton), ethylene glycol (100%, PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), polyaluminum chloride (PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium thiosulfate (40%, PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM).Lower-density chemistries such as acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%, 316SS), urea solution (50%, PP/PVC), ferrous sulfate (20%), magnesium chloride (30%), and sodium carbonate (30%) are compatible as well, though they only need a 1.35–1.9 SG tank — this 1.9 SG shell simply gives you extra margin.Match every fitting and gasket to the material called out for your chemical, and check the full Chemical Compatibility Database before you order.

The mistake to avoid

Do not read the 1.9 SG rating as license to skip the gasket check.On the aggressive oxidizers and strong acids above — hydrochloric, sulfuric, phosphoric, hydrofluoric, hydrogen peroxide, and sodium hypochlorite — EPDM will fail; those seats require Viton (or Aflas on peracetic acid), while 316SS is specified for DEF and peracetic acid.Confirm the exact concentration and temperature against the OEM chart, since the ratings shift with both.If you're carrying and labeling hazardous chemistry, the tank label and signage compliance guide and the chemical sampling protocol guide keep your program inspection-ready.
