An examination of the conditions required to obtain the optimal performance of semicontinuous and continuous parametric pumps, defined by the achieving of the maximum possible solute free product for a given column height, was undertaken. The model system sodium nitrate ? water on an ion retardation resin adsorbate was employed. Equations defining maximum values of certain important parameters such as the bottom product flow rate and reservoir displacement rate were developed by extending previous theories of parametric pumping. Experimental runs were carried out using parameters whose values were both less than and greater than the maximum values predicted for optimal performance. It was found that for pumps operating with parameter values less than the limiting maximum values, complete removal of solute from the bottom of the column was obtained. Furthermore, for those pumps for which the parameter values were greater than the predicted maximum quantities only partial removal of solute was observed. The experimental results agreed quantitatively as well as qualitatively with the theory for almost all runs.
