The Snyder Industries 150 Gallon Plastic Chemical Feed Station Tank is a 1.9 specific-gravity HDLPE vessel built for day-tank and chemical feed duty where you need a heavy-rated polyethylene tank in a compact footprint. Molded in white high-density linear polyethylene, it stands 62 inches tall on a 43 x 56 inch footprint - 62 in tall, 43 in wide, 56 in long - and holds 150 gallons. The 1.9 SG rating is the headline spec: it lets this tank carry dense chemistry up to a 1.9 specific gravity, which is why it shows up in chemical-tank and feed-station searches.
Will it hold your chemical and your weight?
Sizing comes down to fluid density. Filled with plain water this 150 gallon tank carries about 1,251 lb; at its 1.9 specific-gravity rating it is engineered for contents up to roughly 2,377 lb. Stay under that 2,377 lb ceiling and confirm your chemical's specific gravity before you fill - a 150-gallon batch of a heavy acid weighs far more than 150 gallons of water, and the SG rating is what determines whether this tank is the right one. The 1.9 SG is the top of the range offered in this footprint, so verify your chemical's specific gravity stays at or under 1.9. Run your fluid through the Tank Sizing Calculator or the Tank Sizing Guide if you are dialing in batch volume and weight. See the technical drawing on this page for fitting locations and dimensional detail before you plumb it.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity. Compatibility depends as much on your fittings and gaskets as on the tank wall, so match the materials below to your chemistry and always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature. With this resin and SG rating it also serves DEF and urea feed duty (DEF 32.5% requires 316SS wetted fittings, not the PVC default) and ethylene and propylene glycol service. The materials and concentrations listed here are the verified service points for this resin and SG rating:
- 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
- Hydrochloric Acid 37% - PVC fittings, Viton gaskets
- Hydrofluoric Acid 48% - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid 26% - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide 50% - PVC fittings, Viton gaskets
- Magnesium Chloride 30% - PVC fittings, EPDM gaskets
- Peracetic Acid 30% - 316SS fittings, Aflas gaskets
- Phosphoric Acid 85% - PVC fittings, Viton 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 Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate 30% - PVC fittings, EPDM gaskets
- Sodium Hypochlorite under 16.5% - PVC fittings, Viton gaskets
- Sodium Thiosulfate 40% - PVC fittings, EPDM gaskets
- Sulfuric Acid 98% - CPVC fittings, Viton gaskets
- Urea Solution 50% - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
Browse the full Chemical Compatibility Database before committing to fitting and gasket materials. Note the pattern: oxidizers and strong acids like sodium hypochlorite, hydrogen peroxide, hydrochloric, phosphoric, and sulfuric acid call for Viton over EPDM, and the hottest-service chemistry (peracetic acid) moves to Aflas - the gasket is the most common mistake on a chemical feed tank, not the tank itself.
Specify it right the first time
A few choices upstream save a service call later. Pick your wetted fitting and gasket materials from the list above for your specific chemical, plan your level sensing before drilling, and label the tank for the chemistry it actually holds. For help with those decisions, see our guides on level gauge selection for chemical service, tank label and signage compliance, and the chemical sampling protocol. If you are weighing primary versus full containment, the Snyder Captor Plus 110% containment vs UL-142 comparison walks through SPCC requirements.
