The Enduraplas 2800 Gallon Green Horizontal Sump Bottom Leg Tank ships with its own steel frame and a sump-bottom design built to drain hard agricultural and industrial liquids. It holds 2,800 gallons in a 1.9 specific-gravity polyethylene shell, and the sloped sump floor pulls product toward a single low point so you can pump the tank down and minimize the heel volume left sitting in the bottom. This is a hauling-class horizontal leg tank: the frame keeps it stable on a skid or trailer, and the green resin cuts UV transmission and algae growth on water-based loads.
Will it work for your load?
The tank measures 145 inches long by 97 inches wide by 76 inches tall, with a 97.0 x 145.0 inch footprint. Plan your pad, trailer deck, or containment around that footprint before you order. The 1.9 specific-gravity rating is the number that matters most here: it tells you how heavy a liquid this tank is engineered to carry. Full of plain water the tank and contents reach roughly 23,352 pounds, but at its maximum rated contents the tank is built to handle up to 44,369 pounds. That spread is exactly why the SG rating exists - a denser liquid weighs far more per gallon than water, so use the max-rated figure, not the water figure, when you size your frame support, trailer axles, and pad. If you are unsure how a given product's density stacks up against capacity, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
Chemical compatibility
This Enduraplas tank is rated at 1.9 specific gravity, and its resin is listed as HDLPE. Because that designation carries a question mark in our data, confirm whether the shell is HDLPE or XLPE with the manufacturer before you commit the tank to chemical service - resin type affects how the tank behaves against aggressive products. With a confirmed resin and the right fittings and gaskets, the 1.9 SG rating opens a wide chemical range. The following are compatible at the concentrations and seal materials shown, per the OEM chemical-resistance chart, which is concentration- and temperature-specific - always match the chart to your exact service conditions:
- Acetic Acid at 60% with PP/PVC fittings and EPDM gaskets
- Aluminum Sulfate at 50% with PVC fittings and EPDM gaskets
- Calcium Chloride at 40% with PVC fittings and EPDM gaskets
- DEF at 32.5% with 316SS fittings and EPDM gaskets
- Ethylene Glycol at 100% with PVC fittings and EPDM gaskets
- Ferric Chloride at 50% with PVC fittings and EPDM gaskets
- Ferric Sulfate at 60% with PVC fittings and EPDM gaskets
- Ferrous Sulfate at 20% with PVC fittings and EPDM gaskets
- Hydrochloric Acid at 37% with PVC fittings and Viton gaskets
- Hydrofluoric Acid at 48% with PP/PVC fittings and Viton gaskets
- Hydrofluosilicic Acid at 26% with PP/PVC fittings and Viton gaskets
- Hydrogen Peroxide at 50% with PVC fittings and Viton gaskets
- Magnesium Chloride at 30% with PVC fittings and EPDM gaskets
- Peracetic Acid at 30% with 316SS fittings and Aflas gaskets
- Phosphoric Acid at 85% with PVC fittings and Viton gaskets
- Polyaluminum Chloride with PVC fittings and EPDM gaskets
- Potassium Carbonate at 50% with PVC fittings and EPDM gaskets
- Potassium Hydroxide saturated with PVC fittings and EPDM gaskets
- Propylene Glycol with PP/316SS fittings and EPDM gaskets
- Sodium Bisulfate with PVC/PP fittings and EPDM gaskets
- Sodium Bisulfite with PVC/PP fittings and EPDM gaskets
- Sodium Carbonate at 30% with PVC fittings and EPDM gaskets
- Sodium Hypochlorite below 16.5% with PVC fittings and Viton gaskets
- Sodium Thiosulfate at 40% with PVC fittings and EPDM gaskets
- Sulfuric Acid at 98% with CPVC fittings and Viton gaskets
- Urea Solution at 50% with PP/PVC fittings and EPDM gaskets
- Zinc Orthophosphate with PP/316SS fittings and EPDM gaskets
- Ozonated Water up to 10 PPM with PVC fittings and EPDM gaskets
For full notes on any of these, see our chemical compatibility reference. Note the seal materials closely: the oxidizers and strong acids on this list - sodium hypochlorite, hydrogen peroxide, sulfuric acid, phosphoric acid - call for Viton rather than EPDM, so match the gasket to the chemical, not just the fitting.
The mistake to avoid
The most expensive error on a tank like this is treating the 2,800-gallon water weight as your design load. Many hauling liquids - fertilizer blends, brines, acids - are far denser than water, and stratification can make the bottom layer denser still. Match your product's specific gravity against the 1.9 rating and the 44,369-pound max-rated figure, and confirm your frame and trailer carry that weight, not the 23,352-pound water number. Our guide on fertilizer-blend tank stratification covers how density-driven layering catches operators off guard, and the writeups on applicator and leg tanks for fertilizer and portable utility tank DOT classification are worth reading before you put a leg tank on the road. Confirm the sump-outlet size, location, and gasket details against the technical drawing on this page before you plumb the drain.
