| Abstract: | Abandoned oil pumps can be refitted into circulating water pumps and used in the vacuum distillation of several chemical compounds with different boiling points. The analysis of the experimental data obtained shows that this refitted pumps has advantages of high vacuum, great pumpage, simplicity, convinience, economy and endurance. |
