The Snyder Industries 200 Gallon Plastic Chemical Feed Station Tank is a 1.9 specific-gravity-rated vessel molded in white High Density Linear Polyethylene (HDLPE), purpose-built as a day tank or feed station for bulk chemical metering. It stands 57 inches tall on a 62 by 76 inch footprint, so it sits wider than it is tall: a low-profile, stable platform for pump skids and level instrumentation. The 1.9 SG rating is the number that matters here. It means the shell is rated to hold liquids up to 1.9 times the density of water, which is why the same tank that holds 1,668 lb of water to the brim carries a maximum rated contents weight of 3,169 lb.
Will it work for your chemical?
Match three things before you buy: the liquid's specific gravity, its chemistry against HDLPE, and the wetted materials on every fitting and gasket. At 1.9 SG this tank covers the dense feed chemicals that lighter tanks cannot, including 98% sulfuric acid and 85% phosphoric acid. The 200 gallon figure is the brim volume, not your working volume. On a feed station you never fill to the vent, so plan real working volume below the overflow line and keep pump suction and level-switch deadband inside usable liquid rather than in freeboard you cannot draw down. Run your batch volume and density through the Tank Sizing Calculator and the Tank Sizing Guide to confirm freeboard for the 200 gallon working duty.
Pad and load planning
Size the foundation to the full 62 by 76 inch footprint and the 3,169 lb maximum rated load, not to the empty weight. The wide footprint is what makes this a low-profile feed tank, but the pad still needs continuous, level contact across the entire 62 x 76 base so the load stays distributed instead of bridging on high spots. A brimful water load is 1,668 lb; at the 1.9 rating the contents alone can reach 3,169 lb, so your slab, saddle, and anchoring need to carry that figure.
Chemical compatibility
This is an HDLPE shell rated to 1.9 specific gravity. Always verify against the OEM chemical-resistance chart at your exact concentration and temperature, and treat the fitting and gasket materials below as part of the rating, not optional extras. Compatible chemistries from the chart include:
- 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 (<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
Two warnings carry most of the field failures on a feed station. First, the gasket: pairing EPDM with an oxidizer like sodium hypochlorite, hydrogen peroxide, or sulfuric acid degrades the seal even though the HDLPE shell is fine, so use Viton where the chart specifies it, and note that peracetic acid uniquely calls for Aflas rather than Viton or EPDM. Second, three services on this chart require metallic 316SS wetted parts, not plastic: DEF, peracetic acid, and zinc orthophosphate (with propylene glycol also rated for PP/316SS). If you are metering any of those, confirm 316SS bulkheads and fittings before ordering rather than defaulting to PVC. The 1.9 SG rating already covers every chemistry on this chart at the listed concentrations, including 98% sulfuric and 85% phosphoric, so no higher-density tank is required for these services.

Specifying fittings, level gauges, and labeling
This listing does not pre-define outlets, bulkheads, or vents, so specify and confirm every fitting around your chemistry at order rather than assuming a standard outlet is included. Our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options for aggressive liquids, and our tank label and signage compliance guide covers NFPA 704 placarding and GHS pictograms once the tank is in service. If secondary containment is on your scope, compare it against the Snyder Captor Plus 110% containment approach, and establish a chemical sampling protocol for ongoing QA. See the technical drawing on this page for fitting locations and dimensional detail.
