The Enduraplas 3200 Gallon Yellow Horizontal Sump Bottom Leg Tank arrives on its own integrated steel frame, holds a true 3,200 gallons of polyethylene capacity, and carries a 1.9 specific gravity rating - the spec that matters most on a horizontal leg tank like this one. The sump bottom drains the tank completely, the cradled leg-and-frame design supports the load across the full footprint, and at 145 inches long by 97 inches wide by 84 inches tall, this is a stationary bulk vessel built for fertilizer blends, water haul, and heavy-density chemical storage. If you have been searching horizontal tank, leg tank, or horizontal sump configurations, this is the high-end Enduraplas option in that class.
Will it work for your load?
Run the numbers before you commit. Filled with water, this tank weighs 26,688 lb - that is the load your pad, your frame anchors, and any transfer equipment have to carry. The 1.9 specific gravity rating is the governor: the maximum rated contents weight of 50,707 lb is simply that water figure scaled by the rating (26,688 x 1.9 is roughly 50,707), so the rating and the max weight describe the same limit, not two separate specs. Read it this way - you can fill this tank to 100% only if your liquid's specific gravity is 1.9 or less; if your liquid is denser than 1.9, this tank is not rated for it and there is no partial-fill workaround on a rated vessel. Footprint is 97.0 x 145.0 inches, so confirm your slab and containment area before delivery. The Tank Sizing Calculator and Tank Sizing Guide will help you match contents weight to the rating, and the technical drawing on this page shows the sump, leg, and frame geometry in detail.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. Before you put any chemical into service, confirm the resin with us - the polyethylene grade (HDLPE versus cross-linked XLPE) determines how the tank stands up to aggressive chemicals, and that is non-negotiable for a buyer storing concentrated acids. Note too that fittings are not pre-installed: the materials below are the recommended fitting and gasket materials per chemical, configured to order. Match the fitting and gasket material to your chemical and confirm thread or flange size with us before ordering. Per the OEM chemical-resistance chart - always concentration- and temperature-specific - this tank is suited to a wide range of services:
- 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
One gasket warning worth its own line: the aggressive oxidizers and strong acids do not seal on EPDM. Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrogen Peroxide (50%), Phosphoric Acid (85%), Sulfuric Acid (98%), and Sodium Hypochlorite (<16.5%) all call for Viton gaskets, and Peracetic Acid (30%) is the one service that requires Aflas. Default to the cheaper EPDM on those and you fail the seal - so spec the gasket to the chemical, not by habit. Start at our chemical compatibility resource for the full picture, and always verify against the manufacturer's concentration- and temperature-specific chart.
Freight and the mistake to avoid
This tank ships LTL from the Enduraplas plant in Neche, ND, freighted live to your ZIP - get your number from the Freight Cost Estimator or call us at 866-418-1777. At 145 x 97 x 84 inches and 26,688 lb empty-of-product but full-of-water weight, this is an oversize, single-piece LTL load moving from one northern-plains origin, so quote early and confirm your offload plan - forklift or crane capacity at the receiving end - before you book. The most common mistake on a 1.9-rated horizontal leg tank is treating the rating as optional: it is the safe-fill governor for dense liquids, and the resin question must be settled with us before any aggressive chemical goes in. For fertilizer-blend planning, read our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification, plus our overview of portable utility tanks and DOT classification.
