Can we help you?

We offer a complete line of pilot plant and small commercial size flotation cells. The units are used in the mineral, chemical, environmental, and industrial applications requiring the efficient dispersion of fine air or gas bubbles in slurries or liquids. The units are designed for continuous trouble-free, 24-hour operation and to handle find and coarse-abrasive slurries.


  • Mechanism: "Sub-aeration" mechanism induces and disperses air or gas in sufficient quantities for virtually all applications. External blower air can also be added, if desired. Gate valve assures positive control of air input to each cell. Lightweight, suspended type unit assembly. Enclosed ball bearing aluminum housing with dust cap. Machined standpipe assures accurate alignment. Impeller-diffuser clearance set at factory. Molded urethane impeller and diffuser assure long-wearing life and permit close clearance setting for high aeration efficiency. They are easily replaceable whereas metal castings are virtually impossible to remove. Variable speed, dual and/or single cell V-belt drives are standard on No. 5, 7 and 8 cells. Froth paddle assembly all cells.
  • Cells: Three sizes of either "cell-to-cell" or "open-flow" design available. One to 16 cells available in bank. "Leakproof" adjustable weirs assure level control. Replaceable variable size sand reliefs. Adjustable slurry recycle ports in each feed plate assure proper flow through feed pipes regardless of new feed rate. Replaceable cell liners provided No. 8 and larger sizes. Front recycle ports with replaceable feed pipes.
