The Snyder Industries 35 Gallon Plastic Chemical Feed Station Tank is a compact, high-specific-gravity vessel built for day-tank and chemical feed duty where bench space is tight but the chemistry is aggressive. Molded by Snyder Industries from white high density linear polyethylene (HDLPE) and rated to a 1.9 specific gravity, this tank carries the headroom most feed chemicals demand. It stands 36 in. tall on a 36 in. x 47 in. footprint, so it tucks alongside metering pumps, day-tank skids, and dosing panels without dominating the room. Verify exact clearances against the technical drawing on this page before you size the pad.
Does this 35 gallon chemical tank work for your application?
The numbers let you self-qualify before you fill. Full of water this tank weighs about 292 lb, but the 1.9 SG rating means it is engineered to carry up to roughly 555 lb of denser contents at full volume. To check your chemistry, multiply your chemical's specific gravity by the 292 lb water weight and confirm the result stays under the 555 lb max rated contents weight: 98% sulfuric (about 1.84 SG) lands near 537 lb and clears; 50% ferric chloride (about 1.5 SG) sits near 438 lb. That spread between water weight and rated contents is the whole reason to buy a high-SG chemical tank rather than a standard water tank. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 35-gallon volume covers your batch and refill cadence. Fitting configuration is not pre-set in this listing, so confirm outlet size and bulkhead placement at order and match the wetted hardware to the compatibility table below; see the technical drawing on this page for outlet and gallon-mark detail.
Chemical compatibility
This is a 1.9 SG HDLPE chemical tank. Compatibility always depends on resin, specific gravity, concentration, and the fitting and gasket materials at every penetration, so confirm your exact chemistry against the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific. The chemicals below are documented for HDLPE at the noted concentrations; each links to its entry in our Chemical Compatibility Database:
- 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
Notice the gasket column changes with the chemistry: oxidizers and strong acids like sulfuric, phosphoric, hydrogen peroxide, and sodium hypochlorite call for Viton, while peracetic acid steps up to Aflas. Specifying EPDM where a chemical demands Viton is the most common and most expensive mistake on a chemical feed tank, because the elastomer fails long before the polyethylene does.
The mistake to avoid
Beyond the gasket trap, the fitting column has its own outliers. DEF, peracetic acid, propylene glycol, and zinc orthophosphate require 316 stainless wetted hardware per the table above — PVC is not rated for those, even though it covers most of the acid list. Match the wetted hardware to the right column (PVC, CPVC, PP, or 316 stainless) rather than reusing whatever bulkhead fitting is on the shelf. One more honest note on the ceiling: at 1.9 SG this is the heaviest-content rating in the standard chemical-tank line, so if your chemistry exceeds 1.9 SG, contact us before ordering — a standard polyethylene tank will not safely carry it. If you are dosing oxidizers, plan your instrumentation early; our guide on level gauge selection for chemical service covers radar versus ultrasonic versus hydrostatic for these duties, and our tank labeling and signage compliance guide walks the NFPA 704 and GHS placarding you will need at the point of use. For batches drawn for lab analysis, the chemical sampling protocol guide keeps your results representative. If secondary containment is on your checklist, compare options in our Captor Plus 110% containment versus UL-142 steel writeup.
