Abstract Numerical calculation of axial force was performed on two seal conditions by commercial CFD software Fluent 6.0 on 100SJB8 and several other models.The axial force was calculated with the pressure on the impeller.As regard to 100SJB8,when the seal was fully closed,the force was toward the impeller back shroud which would open the seal;when there was a 0.5 mm clearance,the force was toward the impeller inlet which would close the seal.By comparison,it is found that the pump could keep self-balancing.The discriminant developed by LU Wei-gang,et al.was evaluated by analyzing the results on several models.The results showed that the discriminant agree with the calculation for most of the cases.deep well pump;end face seal;axial force;self-balancing impeller;CFD
