The Snyder Industries 150 Gallon Plastic Chemical Feed Station Tank is a 1.9 specific-gravity chemical tank molded in High Density Linear Polyethylene for day-tank and feed-station duty where the stored chemistry is heavier than water. It stands 78 inches tall on a 43 x 56 inch footprint, holds 150 gallons, and carries a maximum rated contents weight of 2,377 pounds at its 1.9 SG rating - the headroom you need for dense solutions that would overload a water-rated tank. White HDLPE lets operators read the level and watch for changes at a glance.
Will this tank work for your chemical?
Two numbers decide fit: weight and specific gravity. Filled with plain water this tank carries 1,251 pounds; at the full 1.9 SG rating it is engineered for up to 2,377 pounds of contents - that works out to roughly 15.8 pounds per gallon, or any fluid up to 1.9 SG. So a quick self-check: 50% sulfuric acid (about 1.4 SG) and 37% hydrochloric acid (about 1.18 SG) both sit comfortably under that ceiling. Verify your chemical's specific gravity against 1.9 before you order. The 43 x 56 inch footprint and 78-inch height tell you whether it clears your doorway, fits the containment pad, and leaves room above for fill lines and a level gauge - if you are spec'ing instrumentation, the level gauge selection guide for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive trade-offs. To size a 150 gallon feed station against your draw rate, run the Tank Sizing Calculator or read the Tank Sizing Guide. As a 150 gallon chemical tank in the Snyder line, it slots into the same family of 150 gallon tank options buyers compare for chemical feed work.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, which gives it the wall strength to store dense acids and concentrated solutions. The resin grade reads as confirmed HDLPE; if your records show any ambiguity, confirm HDLPE versus XLPE before chemical service, since the two resins behave differently against oxidizers. The decision that actually trips people up is the wetted material, not the tank. Match every fitting and gasket to the chemical and verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific. As a quick guide from the data below: most salts and bases run on EPDM gaskets; oxidizers and strong acids (sodium hypochlorite, hydrogen peroxide, sulfuric, phosphoric, hydrochloric, hydrofluoric, hydrofluosilicic) need Viton; peracetic acid needs Aflas; and DEF, peracetic acid, propylene glycol, and zinc orthophosphate call for 316SS fittings.

| Sodium carbonate | 30% | PVC | EPDM |
| Sodium hypochlorite | <16.5% | PVC | Viton |
| Sodium thiosulfate | 40% | PVC | EPDM |
| Sulfuric acid | 98% | CPVC | Viton |
| Urea solution | 50% | PP/PVC | EPDM |
| Zinc orthophosphate | - | PP/316SS | EPDM |
| Ozonated water | up to 10 PPM | PVC | EPDM |
Where a concentration shows a dash, the OEM chart lists the chemistry as compatible without a single rated concentration - confirm your exact strength against the chart before ordering. Ozonated water is compatibility-listed but does not yet have a dedicated page; browse the full Chemical Compatibility Database for it and any chemistry not shown here.
The mistake to avoid
The costliest error on a chemical feed station is mismatching the wetted materials, not the tank. The gasket call-outs in the table above are deliberately not uniform: install an EPDM gasket on a sodium hypochlorite, hydrogen peroxide, or sulfuric line - all of which require Viton - and it will fail in service. Peracetic acid goes a step further and requires Aflas. Confirm both the fitting material and the gasket material for your exact chemical and concentration against the OEM chart, and for high-acid service like sulfuric (98%) and hydrochloric (37%) double-check the bulkhead and valve body materials too.
