The Snyder Industries 330 Gallon HDLPE Chemical Feed Station Tank is built for one of the hardest jobs in chemical storage: holding aggressive bulk liquids like concentrated sulfuric acid in a containment tank with a built-in basin, so a primary breach stays caught instead of spreading. This is a Specialty Tank molded from high density linear polyethylene (HDLPE), rated to a 1.9 specific gravity, with a 330 gallon working capacity. It stands 68 inches tall on a footprint of 62 inches (width) by 76 inches (length), so you can lay out the containment pad knowing which dimension faces your access aisle. The white tank lets operators read the liquid level and inspect for fill or stratification at a glance.
Will it work for your application?
The 1.9 specific gravity rating is the number that matters most on a chemical feed station. It tells you the tank wall is engineered to carry liquids heavier than water without overstressing the polyethylene, which is why a 330 gallon vessel can be trusted with dense acids. Concentrated sulfuric acid at 98% is roughly 1.84 SG, which sits under the 1.9 rating, so this tank carries that product within its rated envelope. Filled with plain water it carries about 2,752 pounds; that water figure is your floor. The number that governs slab design and anchoring is the 5,229 pound maximum rated contents weight, because at 1.9 SG a tank full of dense acid lands far above the water weight. Size the slab, the secondary containment area, and any tie-downs to that 5,229 pound design load. If you are confirming capacity against your dosing schedule, the Tank Sizing Calculator and the Tank Sizing Guide walk you through usable volume versus rated volume.
Chemical compatibility
This tank is HDLPE rated to 1.9 specific gravity, which puts a wide band of dense industrial chemicals in range. The chemical that defines this tank, sulfuric acid at 98%, requires CPVC fittings and Viton gaskets, not the PVC used for most of the other listed chemicals. Speccing PVC fittings on 98% sulfuric is exactly the expensive mistake to avoid. Compatibility always depends on resin, specific gravity, concentration, temperature, and the fitting and gasket materials at every penetration, so match the OEM chemical-resistance chart to your exact concentration and service temperature before you commit. The following chemicals are listed compatible with this resin and SG class, with the fitting and gasket materials called out for each:
- Sulfuric Acid at 98% concentration, CPVC fittings, Viton gaskets
- Hydrochloric Acid at 37%, PVC fittings, Viton gaskets
- Hydrofluoric Acid at 48%, PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid at 26%, PP/PVC fittings, Viton gaskets
- Phosphoric Acid at 85%, PVC fittings, Viton gaskets
- Hydrogen Peroxide at 50%, PVC fittings, Viton gaskets
- Sodium Hypochlorite at under 16.5%, PVC fittings, Viton gaskets
- Peracetic Acid at 30%, 316SS fittings, Aflas gaskets
- Acetic Acid at 60%, PP/PVC fittings, EPDM gaskets
- Ferric Chloride at 50%, PVC fittings, EPDM gaskets
- Ferric Sulfate at 60%, PVC fittings, EPDM gaskets
- Ferrous Sulfate at 20%, PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50%, PVC fittings, EPDM gaskets
- Polyaluminum Chloride, PVC fittings, EPDM gaskets
- Calcium Chloride at 40%, PVC fittings, EPDM gaskets
- Magnesium Chloride at 30%, PVC fittings, EPDM gaskets
- Sodium Carbonate at 30%, PVC fittings, EPDM gaskets
- Sodium Thiosulfate at 40%, PVC fittings, EPDM gaskets
- Sodium Bisulfate, PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite, PVC/PP fittings, EPDM gaskets
- Potassium Carbonate at 50%, PVC fittings, EPDM gaskets
- Potassium Hydroxide at saturated concentration, PVC fittings, EPDM gaskets
- Zinc Orthophosphate, PP/316SS fittings, EPDM gaskets
- Propylene Glycol, PP/316SS fittings, EPDM gaskets
- Ethylene Glycol at 100%, PVC fittings, EPDM gaskets
- Urea Solution at 50%, PP/PVC fittings, EPDM gaskets
- DEF at 32.5%, 316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM, PVC fittings, EPDM gaskets
The gasket material is not one size fits all: oxidizers and strong acids like sulfuric, hydrochloric, hydrofluoric, phosphoric, hydrogen peroxide, and sodium hypochlorite call for Viton, peracetic acid calls for Aflas, and the salts and glycols run on EPDM. Specifying the wrong elastomer is the most common and most expensive mistake on a feed station, because the tank can outlast a gasket that fails in months. Confirm every selection against the OEM chemical-resistance chart at your concentration and temperature, then cross-reference our Chemical Compatibility Database before ordering fittings.
Specifying the rest of the system
The fitting sizes and bulkhead locations for this tank are not yet listed on this page, so call 866-418-1777 to confirm the inlet, outlet, vent, and fill-port penetration schedule before you order CPVC pipe and Viton seals. A containment feed station is also more than a tank. Decide your level-measurement method early; our guide on level gauge selection for chemical service compares radar, ultrasonic, hydrostatic, and magnetostrictive so you do not over-buy. If you are weighing this integrated basin against a separate UL-142 steel approach, the Captor Plus 110% containment vs UL-142 SPCC comparison lays out the regulatory trade-offs. Before the tank goes into service, get the labeling and NFPA 704 signage right, and set a chemical sampling protocol so your lab results reflect what is actually in the tank. The basin dimensions and overall geometry are documented on the technical drawing on this page.
