The Snyder Industries 35 Gallon Heavy Duty Cone Bottom Mixing Tank is built for full-drain chemical batching where you need every gallon to evacuate through the cone. Molded in black High Density Linear Polyethylene with a 1.9 specific gravity rating, this 35 gallon cone bottom tank carries a 30 x 30 inch footprint and stands just 24 inches tall, putting heavy, dense liquids over a small floor area without crowding your mix station.
Will it work for your batch
The 1.9 SG rating is the number to plan around: the tank wall is engineered to hold contents up to 1.9 times the weight of water. Empty it is easy to handle; filled with plain water it carries roughly 292 pounds, and loaded to its full rated density it is built to carry up to 555 pounds of contents. That ceiling checks out against the rating itself - 292 pounds of water times 1.9 lands right at the 555 pound figure - so a skeptical engineer can verify the math before trusting the number. Match that 555 pound ceiling against the density of whatever you are mixing before you fill. At 1.9 specific gravity this is already the heaviest-duty resin rating offered in this cone bottom size and family; there is no higher-SG step-up to move to, so you are sizing against the top of the range. Because it is a cone bottom design, this tank must sit in a matching stand or rack rather than on a flat floor - confirm your stand before ordering, and see the cone bottom tank stand compatibility matrix for Norwesco, Snyder, and Enduraplas fit. To compare this 35 gallon size to your throughput, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity. Its fitting configuration is not pre-specified - you select the outlet, valves, and gaskets to match your chemical, so nothing ships installed by default. Compatibility always depends on concentration and temperature, so verify against the OEM chemical-resistance chart for your exact conditions. The fitting and gasket materials below come from that data and shift by chemical. Most candidates run plastic PVC or PP fittings; the metallic-fitting exceptions are DEF (316SS) and Peracetic Acid (316SS), with Propylene Glycol and Zinc Orthophosphate allowing PP/316SS. On gaskets, EPDM is the default, but a specific set demands Viton - Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Phosphoric Acid, Sodium Hypochlorite, and Sulfuric Acid - and Peracetic Acid alone requires Aflas. Sulfuric Acid also calls for CPVC fittings rather than PVC. Specifying EPDM where Viton or Aflas is required is the most common and most expensive mistake on a tank like this. Based on our compatibility data, this tank is a candidate for service with:
- 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
Cross-check your exact chemical, concentration, and temperature in the Chemical Compatibility Database before you order valves and gaskets.
Getting it dialed in
For chemical batching, keep stratification in mind: dense blends can layer if they sit, which throws off your mix downstream. The cone bottom helps here by promoting full drainage and recirculation, and the fertilizer-blend stratification guide covers the field checks that catch a stratified tank early. If you are metering or alarming on level, the level gauge selection guide for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive trade-offs. If secondary containment is part of your spec, the Snyder Captor Plus 110% containment comparison lays out the options.
