The Snyder Industries 330 Gallon XLPE Chemical Feed Station Tank is a cross-linked polyethylene vessel rated to 1.9 specific gravity, built for bulk chemical metering and day-tank duty where you need a stable, contained supply point for a feed pump or dosing skid. It holds 330 gallons in a white tank standing 69 in. tall on a 62 x 76 in. footprint (62 in. wide by 76 in. long), so plan your pad and clearance around those numbers before you order. This is a Snyder chemical tank built for aggressive XLPE service, not a water cistern.
Will this tank work for your chemical?
Two specs decide it: the 1.9 specific-gravity rating and the XLPE resin. The 330 gallons is gross capacity - a feed or day tank is sized on the usable volume that sits above your pump suction, between the high and low cutouts, so size the tank on that working band, not the nameplate. On weight, this tank carries a maximum rated contents weight of 5,229 lb. Plain water (1.0 SG) at 330 gallons is about 2,752 lb, which leaves roughly 2,477 lb of headroom for denser chemistries. You can verify your own liquid with a single check: gallons x 8.34 x your chemical's specific gravity must stay under 5,229 lb, and that SG must be at or under 1.9 at your operating temperature. The Tank Sizing Calculator and Tank Sizing Guide help you match the gallon volume to your feed rate.
Chemical compatibility
This is an XLPE tank rated to 1.9 specific gravity. The chemicals below are compatible with XLPE at the concentrations shown - always match your exact strength and operating temperature against the specific chemistry before service, since compatibility is concentration- and temperature-specific. Fitting and gasket materials are listed because the tank wall is only half the seal; the wrong gasket fails before the resin does.
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Do not default to PVC across the board. DEF (32.5%) calls for 316 stainless fittings, propylene glycol calls for PP or 316SS, and acetic acid, hydrofluosilicic acid, and urea solution all run PP/PVC. Watch the gaskets too: most rows are EPDM, but hydrofluosilicic acid here is paired with Viton - get that elastomer right or the joint leaks first. Ozonated water is capped at 10 PPM on this resin; oxidizer service is concentration-limited, so for anything stronger, or any chemistry not listed here, check the full Chemical Compatibility Database before you commit.
The mistake to avoid
The number-one error on a chemical feed station is treating the 1.9 SG rating as a suggestion. 1.9 SG is the ceiling for this vessel; running a denser liquid, or running near-full at a temperature that softens the wall, overstresses the structure. There is no higher-SG version of this tank - chemistries above 1.9 SG, oxidizers beyond the rows shown, or elevated-temperature service need a different vessel specified through the compatibility database or a call to us. And match your fittings and gaskets to the chemical, not to whatever the installer has on the truck - the lists above are your reference. For dosing accuracy, pair the tank with the right level instrument; our guide on tank level gauge selection for chemical service compares radar, ultrasonic, hydrostatic, and magnetostrictive sensors for exactly this duty. Before you fill, label the tank correctly - see tank label and signage compliance - and set a chemical sampling protocol so your lab results stay trustworthy. If you need secondary containment, our Snyder Captor Plus 110% containment comparison walks through the SPCC math.
