750-gallon cone bottom tank built for full-drain mixing and batch processing. Manufactured by Chemtainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 16.7 pounds per gallon. Cone bottom design provides 100% drainage — no residual liquid left behind between batches.
The 750 Gallon 15 Degree Plastic Vertical Cone Bottom Tank is designed for chemical processors, water treatment plants, and agricultural operations requiring complete tank drainage. At 750 gallons, this cone bottom tank is sized for batch processing, chemical mixing, and applications where complete drainage between cycles is non-negotiable. The cone geometry eliminates the dead volume that flat-bottom tanks leave behind.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. The 2.0 specific gravity rating means this tank is built with significantly heavier wall sections than a standard water tank — necessary to safely contain liquids weighing up to 16.7 pounds per gallon. That extra wall thickness is not optional when you are storing aggressive industrial chemicals. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. UV stabilizers are compounded directly into the resin — not a surface coating — for outdoor service life that lasts the full warranty period and beyond.
This tank measures 69 inches tall with a 64-inch diameter, requiring 22.3 square feet of level ground. Empty weight is 225 pounds. At full capacity with a 2.0 SG liquid, expect approximately 12,735 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Must be installed on the manufacturer-supplied or compatible stand rated for the full loaded weight. Never rest a cone bottom tank directly on its apex.
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" 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.
