Abstract To meet the requirement of continuous production of refinery units, quit high requirements are imposed on the shaftsealing of pump, eventually, magnetic drive pump technique is developed for transporting hot oils. Flow filed in a high temperature and pressure magnetic drive pump was simulated numerically by using software ICEM and CFX. Pressure, velocity and streamline distributions were analysed, and the pump characteristic curves of high temperature oil and 20 ℃ water were compared, further axial thrust acting on the pump rotor was estimated to examine the rationality of pump design. The magnetic derive pump can work properly when flow rate is in a range of 1.0Qd -1.6Qd, specially, internal flow lines are smooth, and the pressure distributions on blade suction and pressure sides are even, and no flow separation phenomenon emerges as well. Physical property of the media shows little effect on magnetic pump performance curves so that the pump is applicable for two kinds of media. The axial thrust generated in inner magnetic rotor can be ignored compared with the axial thrust by the other factors. The total axial thrust is decreased with increasing flow rate. The resultant force in the impeller flow passages increases with increasing flow rate, but also the static pressure around the impeller is reduced; hence the total axial thrust is lowered. Hydraulic structure and axial thrust of the magnetic drive pump have been verified, the paper provides a reference to design of high temperature and pressure magnetic derive pump.
