The Snyder Industries 330 Gallon Plastic Chemical Feed Station Tank is a white, high density linear polyethylene (HDLPE) vessel built for bulk chemical storage and dosing on tight feed-station and metering-skid layouts. Molded to a 1.9 specific gravity rating, it carries the dense, aggressive chemistries a standard 1.0 or 1.5 SG tank cannot - covering service up to chemistries like 98% sulfuric acid, 85% phosphoric acid, and 50% ferric chloride. If you have been searching for a 330 gallon white Snyder chemical tank sized for concentrated solutions, this is the unit.
Quick specs: 330 gallons | 86"H x 62"W x 76"L | 62 x 76 in footprint | 2,752 lb full of water (SG 1.0), engineered for up to 5,229 lb of contents at the 1.9 SG rating | white HDLPE.
Will it hold your chemical and your weight?
The 1.9 SG rating is the number that matters: it tells you the wall thickness and resin were specified for liquids heavier than water, which is exactly what you need for dense acids and concentrated solutions. Filled with water the contents weigh 2,752 lb; at the full 1.9 rating the tank is engineered to carry up to 5,229 lb. Confirm your chemical's specific gravity against the 1.9 rating before you order, then use the Tank Sizing Calculator and Tank Sizing Guide to check fill volume and weight loading against your slab or containment pad. The 62 by 76 inch footprint and 86 inch height are on the technical drawing on this page - verify clearances for fill, mixing, and lid access before the tank arrives.
Chemical compatibility
This tank is HDLPE rated to 1.9 specific gravity, a true heavy-chemistry vessel. The chemicals below are compatible with this resin and SG rating; compatibility is concentration- and temperature-specific, so always cross-check the OEM chemical-resistance chart for your exact concentration and operating temperature before service.

- 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

- 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
The gasket choice changes with the chemistry, and getting it wrong is the most common feed-station failure: Viton for sodium hypochlorite, hydrochloric, hydrogen peroxide, phosphoric, and sulfuric acid; Aflas for peracetic acid; EPDM for the salts, glycols, and most everything else. Watch the fitting exceptions too - DEF and peracetic acid need 316SS, propylene glycol and zinc orthophosphate need PP/316SS, and 98% sulfuric acid needs CPVC rather than stock PVC.

The mistake to avoid on this tank
The biggest error is treating the 1.9 SG rating as a license to skip the resin and elastomer questions. Because this resin is shown as HDLPE, confirm the resin grade with us before chemical service if your application demands cross-linked (XLPE) walls. The fittings field on this tank is open - it ships as a bare vessel, with bulkheads, gaskets, and fitting materials specified to your chemistry at order, so plan that package up front rather than ordering a stock PVC bulkhead that your DEF, peracetic, or 98% sulfuric service can't use. Plan level instrumentation early (see Tank Level Gauge Selection for Chemical Service), get labels and hazard placarding right (Tank Label and Signage Compliance), and set a sampling cadence for your chemistry (Tank Chemical Sampling Protocol). If your install needs full secondary containment, compare options in our Snyder Captor Plus 110% Containment vs UL-142 guide.
