The composition and work principles of a positive displacement pump（PD pump） WJP were introduced and the comparative analyses were made between the positive and negative displacement pump（ND pump） WJP.Based on the traditional WJP theory,a study of introducing correction coefficients of momentum/kinetic and the impact factors of boundary layer and pump suction was carried out to investigate the energy transformation and the theory of PD pump WJP,such as the calculation of thrust and efficiency.The related conclusions are extended to design high performance PD pump WJP units.
