A high vacuum sorption pump with a speed of 14 I/sec for air has been developed and its various characteristics are given. A final pressure of 2 x 10-7 torr was achieved by this pump in a two-stage pumping of air from 760 torr. The pumping speeds for various gases were investigated in the pressure r
