Abstract
Hickman has made a contribution to pump development which is outstanding since the original work of Gaede and Langmuir. We have checked his conclusions regarding the desirability of incorporating a distillation process in conjunction with the pumping operation. The results of our work are incorporated in a pump design based upon a design of Hickman's. This pump: (1) yields very low ultimate vacuums; (2) operates against moderately high backing pressures; and (3) is made entirely of metal. In addition, we have made ``life tests'' on Octoil which indicate its superiority over available petroleum distillates as regards vapor pressure and ability to withstand abuse.Keywords
