The Enduraplas 1900 Gallon White Horizontal Sump Bottom Leg Tank rides on its own steel frame for over-the-road agricultural transport, holding 1900 gallons in a natural white polyethylene shell rated to the maximum 1.9 specific gravity class. The horizontal leg tank body measures 130 inches long by 71 inches wide by 70 inches tall. The 1.9 SG rating is the headline number: this is built to move dense fertilizer blends and heavy chemicals, not just water. The sump bottom gives the tank a low drain point so dense product gravity-drains completely instead of leaving residue settling on a flat floor, which matters when a blend is prone to salting-out or stratifying between loads.
Will this Enduraplas horizontal sump leg tank work for my haul?
Size the load to the contents, not just the gallons. Filled with water (SG 1.0) this tank carries 15,846 pounds, and at its full 1.9 specific gravity ceiling it is engineered for up to 30,107 pounds of contents — that figure already bakes in the 1.9 multiplier, so don't double-count it. The 71-by-130-inch footprint defines how it sits on a trailer or skid, so confirm your deck and tie-down points against that before you spec the truck. Because contents weight nearly doubles between water and a 1.9 SG product, run your actual fluid density through the Tank Sizing Calculator and review the Tank Sizing Guide to confirm the rated weight covers what you intend to haul. At 1.9 SG this tank is already at the top of the poly range — there is no heavier-rated tank to step up to.
Chemical compatibility
This tank is molded from polyethylene rated to 1.9 specific gravity, and the resin is listed as HDLPE but not fully confirmed — for a high-SG chemical haul tank the resin classification governs the entire compatibility list, so verify HDLPE versus crosslinked (XLPE) construction with us before putting it into chemical service. The single most common spec error here is defaulting every fitting and gasket to EPDM: the materials shift by chemical, with Viton called for on oxidizers and strong acids, Aflas on peracetic acid, and 316 stainless wetted fittings on DEF. Match per chemical, never blanket-EPDM, and confirm every selection against the OEM chemical-resistance chart at your specific concentration and temperature. Within this tank's 1.9 SG rating, the following are listed as compatible:
- 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
