The Enduraplas 2800 Gallon White Horizontal Sump Bottom Leg Tank ships as a complete unit on its molded frame: a 2,800-gallon polyethylene tank measuring 145 in long by 97 in wide by 76 in tall, in Natural White. The sump bottom drains toward a low point so you can empty the tank fully, and the integrated leg/frame design is built for stationary outdoor storage of water and the chemicals listed below. This is a heavy-haul item, so the numbers below matter before you order.
Will it work for your job?
The tank carries a 1.9 specific gravity rating, which means it is engineered to hold contents up to 1.9 times the density of water. Filled with plain water it holds about 23,352 lb, and the polyethylene shell is rated to carry up to 44,369 lb of contents at the full 1.9 SG. Confirm your liquid's density falls inside that window: a 1.9-rated horizontal leg tank covers heavy chemicals and fertilizer blends that a standard 1.0 or 1.5 SG tank cannot. Use the Tank Sizing Calculator and the Tank Sizing Guide to match the 2,800-gallon capacity and the 97.0 x 145.0 in footprint to your pad before delivery. Buyers searching for an Enduraplas horizontal leg tank or a sump-bottom horizontal tank land here because few sites publish the full water weight and rated SG side by side.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. Its resin is logged as HDLPE pending confirmation, so verify HDLPE versus XLPE with us before putting this tank into chemical service. Compatibility, fitting material, and gasket material must be matched to the exact concentration and temperature of your chemical against the OEM chemical-resistance chart. Based on that chart, this tank is suitable for:
- 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
Concentrations shown are the chart reference points; confirm yours against the OEM chemical-resistance chart for your temperature, and see our full chemical compatibility resource before specifying fittings and gaskets.
The mistake to avoid
Do not pair this 1.9 SG tank with the wrong gasket or fitting material. Sodium hypochlorite, sulfuric acid, phosphoric acid, hydrogen peroxide, and the hydrofluoric and hydrofluosilicic acids on the list call for Viton (or Aflas for peracetic acid) rather than EPDM, and the wetted parts are specific too: sulfuric acid needs CPVC, DEF and peracetic acid need 316SS, sodium bisulfate and bisulfite accept PVC or PP, and propylene glycol and zinc orthophosphate take PP or 316SS. Matching the tank's SG rating but mismatching the seal material is the most common way these installs fail, so build to the table above rather than a single default. And because the resin is logged as HDLPE pending confirmation, settle HDLPE versus XLPE before any aggressive chemical goes in.
