A measurement technique for obtaining the pumping performance of a centrifugal collector under microgravity has been developed and evaluated through microgravity experiments. These tests have been conducted under conditions such that the pressure sensors cannot easily detect the pressure rise of the liquid working fluid. These conditions have a pressure increase smaller than 400 Pa. The characteristic of the head produced in a centrifugal collector calculated from experimental data agrees well with that predicted theoretically from the velocity and the pressure generated by rotation of the centrifugal collector. It is concluded from this result that the measurement technique can correctly obtain the pumping performance of the centrifugal collector under microgravity. The centrifugal collector has produced the head of 0.041 m at the rotation speed of 223 rpm under microgravity. The working fluid is silicon oil. This head corresponds to the pressure rise of approximately 390 Pa.
