A semicontinuous parametric pump with batch operation during one half‐cycle and continuous operation in the other half‐cycle was experimentally investigated using the model system toluene‐ n ‐heptane on silica gel adsorbent. A mathematical model based on an equilibrium theory is presented and is found to be in good agreement with the experimental results. Furthermore, it is shown that when the penetration distance for the cold cycle is less than or equal to that of the hot cycle and the height of the column, the rate of production of pure solvent by this pump may become quite large compared to the rate of production by a pump in which operation is continuous during both half‐cycles.
