Enduraplas 1200 Gallon Black Horizontal Sump Bottom Leg Tank

The Enduraplas 1200 Gallon Black Horizontal Sump Bottom Leg Tank (SKU THD01200B) is a 1,200-gallon polyethylene haul tank built for moving dense liquid down the road and across the field.It measures 102 inches long by 70 inches wide and stands 63 inches tall on a 70.0 x 102.0-inch footprint.The 1.9 specific gravity rating is the key number: at 1.9 SG, this is the top density rating in the horizontal leg-tank line per our data, built to carry heavy fertilizer blends and concentrated chemicals that would overload a standard 1.0 or 1.9 SG water tank.Black polyethylene also holds up to UV and sunlight better than translucent or natural resins, which matters on a tank that lives outdoors on a sprayer or nurse rig.

Will it work for your load?

Weight decides everything here.Filled with water at 8.34 lb/gal, this tank holds about 10,008 pounds of contents.At its full 1.9 SG rating, the maximum rated contents weight climbs to roughly 19,015 pounds - close to five tons of dense fluid.Spec your trailer, axles, and tie-downs against the loaded figure for your actual fluid, not against plain water.The "Sump Bottom" name is a model label; our data does not include fitting or outlet locations or a verified sump-drain spec, so confirm outlet position and size from the technical drawing on this page or with us before you plumb it.Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity and loaded weight to your hauling setup.

Chemical compatibility

Resin type is NOT confirmed on this tank - it is recorded as HDLPE but unverified - so confirm HDLPE versus XLPE with us before committing this tank to any chemical service.Keep two ideas separate: the 1.9 SG rating governs how much weight the shell carries, not how it resists a given chemical.Compatibility is concentration- and temperature-specific; match your exact concentration and operating temperature, and note that no fittings are defined in our data for this tank - fittings and gaskets are a separate selection sized to your fluid, not included with the shell.

Fluids that handle on this resin with PVC or PP fittings and EPDM gaskets include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), magnesium chloride (30%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium thiosulfate (40%), urea solution (50%), and zinc orthophosphate.DEF (32.5%) calls for 316SS fittings with EPDM.Ozonated water (up to 10 PPM) handles on PVC fittings with EPDM as well; it does not yet have a dedicated reference page.

Strong oxidizers and acids handle here but require Viton gaskets rather than EPDM: hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), phosphoric acid (85%), and sodium hypochlorite (under 16.5%).Sulfuric acid (98%) needs CPVC fittings with Viton, and peracetic acid (30%) needs 316SS fittings with an Aflas gasket.The most common mistake on a chemical tank is getting the gasket or fitting material wrong - the polyethylene shell can be fine while an EPDM gasket fails against an oxidizer.We will spec the correct fitting and gasket to your exact chemical and concentration; confirm every pairing against our chemical compatibility reference before you order.

Freight and ordering

This tank ships LTL freight from the Enduraplas plant in Neche, ND, and freight is quoted live to your ZIP code rather than rolled into the listed price.Because a large horizontal leg tank is heavy and bulky, run your delivery address through the Freight Cost Estimator for an accurate rate.If you are spec'ing this for fertilizer work, review our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification before you commit to a blend program.Questions on fit, fittings, or freight?Call 866-418-1777.
