The Enduraplas 1400 Gallon White Horizontal Sump Bottom Leg Tank w/ Frame is a transport-oriented polyethylene tank built for moving heavy liquids over the road. It holds 1,400 gallons of natural white polyethylene, measures 102" long by 70" wide by 71" tall, and rides on an integrated steel frame with a sump bottom that drains the load completely. The 1.9 specific gravity rating is the headline number here: this tank is engineered to carry dense agricultural and industrial liquids, not just water, which is exactly why farmers and applicators searching for an Enduraplas horizontal leg tank or sump-style horizontal tank land on this size.
Will it work for your liquid?
Match the weight to the load before you commit, and plan to the heavier number. The same tank that hauls 11,676 lb of water carries up to 22,184 lb of 1.9-SG fertilizer or brine, an 89% jump, so size your trailer, axle, and hitch to 22,184 lb, not the water weight. That 1.9 SG rating is also the ceiling for this polyethylene line, which means there is no denser-rated sibling you need to step up to for heavy agricultural or industrial chemistries: this tank already sits at the top of the range. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your liquid's weight against the 70" x 102" footprint before loading. The sump bottom and frame are designed so the tank empties cleanly and stays supported under load.
Chemical compatibility
This tank is molded from polyethylene and carries a 1.9 specific gravity rating. The resin grade is unconfirmed in our data, so confirm HDLPE versus XLPE (cross-linked) with us before putting it into chemical service, because the two resins behave very differently against aggressive liquids. Per the OEM chemical-resistance chart, which is always concentration- and temperature-specific, this tank stores the following at the listed conditions:
Acetic Acid (60%), details, PP/PVC fittings, EPDM gaskets; Aluminum Sulfate (50%), details, PVC, EPDM; Calcium Chloride (40%), details, PVC, EPDM; DEF (32.5%), details, 316SS fittings, EPDM gaskets; Ethylene Glycol (100%), details, PVC, EPDM; Ferric Chloride (50%), details, PVC, EPDM; Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Potassium Carbonate (50%), Sodium Carbonate (30%) and Sodium Thiosulfate (40%) all on PVC with EPDM; Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Hydrogen Peroxide (50%), Phosphoric Acid (85%) and Sodium Hypochlorite (<16.5%) on PVC or PP/PVC fittings with Viton gaskets; Peracetic Acid (30%) on 316SS with Aflas; Potassium Hydroxide (Saturated), Polyaluminum Chloride, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Urea Solution (50%) and Zinc Orthophosphate on PVC/PP or PP/316SS fittings with EPDM; and Sulfuric Acid (98%) on CPVC with Viton. Ozonated Water (up to 10 PPM) runs on PVC fittings with EPDM gaskets per the OEM chart, with a dedicated page pending. See the full chemical compatibility resource and each chemical's page for the verified gasket and fitting build, and always cross-check against the OEM chart at your specific concentration and temperature.
The mistake to avoid
The expensive error on a 1.9 SG tank is matching fitting and gasket materials to the tank but ignoring the liquid. As listed above, DEF and Peracetic Acid require 316 stainless steel fittings, while the strong acids (hydrochloric, hydrofluoric, phosphoric, sulfuric) and sodium hypochlorite move off the default EPDM to Viton, and Peracetic Acid to Aflas. Specify the wrong elastomer and the gasket fails long before the polyethylene does. Tell us your chemical and concentration and we will build the correct PVC, CPVC, PP, or 316SS fitting set with the matching EPDM, Viton, or Aflas gaskets to order. And because the resin grade is unconfirmed, settle the HDLPE-versus-XLPE question with us first if you are storing anything more aggressive than water.
