Abstract The axial thrust is always a problem which researcher pay attention to. The former researcher has brought forward many methods of balancing axial thrust of the pump. In this paper the theory is proved that increasing back sealing ring can balance the axial thrust, and the theory is testified by quoting experiment result of literature. This method is simply in practice and can realize pump operation under negative axial thrust.
