In this paper, one aerospace centrifugal pump with flowrates of 1~2g/s was developed which was applicable to the mechanically pumed two phase loop (MPTL) system. Moreover, an experimental test platform was built to test and verify the performances of pump. Besides, the environmental adaptation tests of the designed pump were verified. Results show that: 1) the flow rate and lift of the pump at the rated working point are 2.043g/s and 0.0517MPa, while the input power is only 9.92W. These can meet requirements of the design indexes. 2) The input power is only 4.71W under the two-phase operation state and this pump can transfer the heat of 240W, and the pump shows a very high energy efficiency ratio (EER). 3) The lift of designed pump is constant at specified rotation speed and it can assure the temperature stability of MPTL system. 4) This pump can meet the requirements of services in vibration, vacuum and thermal cycling environments.
