The Snyder Industries 30 Gallon Heavy Duty Cone Bottom Mixing Tank is built for chemical service where the contents need to drain completely and stay mixed. It holds 30 gallons in a compact 27-inch by 27-inch footprint and stands 20 inches tall, molded in Natural White High Density Linear Polyethylene with a 1.9 specific gravity rating. That 1.9 rating makes it a true heavy duty cone bottom tank rather than a light water-service unit, and at 1.9 it sits at the top of the polyethylene density range, so there is no heavier-rated step up to size into for this footprint.
Will it work for your application
The cone bottom drains by gravity, so batch chemicals and mixed fertilizer blends empty out instead of settling on a flat floor. Because the floor is conical, the tank does not stand on its own; it needs a matching cone bottom stand or conical support to sit level and drain fully. Two top openings handle charging and service: a 20-inch PE threaded, vented lid plus a manway with 15-inch access, so you can fill the tank, drop in an agitator shaft, and reach the interior through the same opening.
- Capacity: 30 gallons, cone bottom
- Footprint: 27.0 x 27.0 in, 20 in tall
- Top opening: 20 in PE threaded, vented
- Manway: 15 in access
- Resin / SG rating: HDLPE, 1.9 specific gravity
Filled with water this tank carries about 250 lb; at its 1.9 specific gravity rating it is engineered to hold contents weighing up to 475 lb, so a heavy brine or acid load stays within its design limit where a 1.0-rated water tank would not. Size your batch against the actual fluid density with the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a fill level.
Chemical compatibility
This tank is HDLPE rated to 1.9 specific gravity. The tank ships bare; the wetted fittings, bulkhead, and gaskets are speced separately to your chemical, so match every wetted component to the service, not just the tank wall, and always confirm against the manufacturer chemical-resistance data at your specific concentration and temperature. Compatible chemicals from our compatibility data include Acetic Acid (60%, PP/PVC fittings, EPDM gasket), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 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), and Ozonated Water (up to 10 PPM, PVC, EPDM). See our full Chemical Compatibility Database to confirm your exact service.
The mistake to avoid
The fitting material matters as much as the tank. Notice that sodium hypochlorite, hydrogen peroxide, the strong acids, and peracetic acid call for Viton, Aflas, or 316SS rather than the EPDM that works for the salts and glycols. Spec an EPDM gasket on a hypochlorite or sulfuric line and the gasket degrades long before the polyethylene does. Because this tank ships without wetted hardware, lock in the fitting, bulkhead, and gasket package to your chemical, concentration, and temperature against the compatibility data before the chemical ever reaches the tank. For stratification-prone blends, review the fertilizer-blend stratification guide, and for level monitoring see the level gauge selection guide for chemical service. Since the cone bottom must be elevated to drain, check the cone bottom tank stand compatibility matrix for the right support.
