850-gallon black storage tank built for agricultural chemical and fertilizer storage. Manufactured by Chem-Tainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 850 Gallon Vertical Storage Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 850-gallon capacity hits the sweet spot for agricultural chemical and fertilizer storage — large enough to be genuinely useful, compact enough to install without heavy equipment or specialized foundations.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. Rated to 1.5 specific gravity, this tank handles liquids up to 12.5 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. UV-resistant black pigmentation provides maximum outdoor durability and inhibits algae growth in stored liquids. Maximum operating temperature is 120° F / 48° C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 124 inches tall with a 48-inch diameter, requiring 12.6 square feet of level ground. Empty weight is 200 pounds. At full capacity with a 1.5 SG liquid, expect approximately 10,834 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Place on a firm, level surface free of rocks or sharp objects that could damage the tank bottom. Ensure adequate ventilation if stored chemicals produce vapors.
This tank ships without pre-installed fittings, giving you full flexibility to position inlet and outlet connections exactly where your plumbing layout requires. Use polyethylene-compatible bulkhead fittings for all penetrations. The 16" Threaded Vented Manway lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. Use schedule 80 PVC or stainless steel bulkhead fittings on the NPT connections. Install a full-port ball valve and consider a Y-strainer to protect downstream equipment.
Chem-Tainer Industries has manufactured chemical-resistant polyethylene tanks in the USA since 1957. Their tanks are specifically engineered for chemical storage applications with wall thicknesses and resin formulations matched to the demands of aggressive chemicals. Backed by a 3-year manufacturer warranty from Chem-Tainer against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
