Abstract
A method of installing the diffusers and impellers on a shaft of a centrifugal pump uses a latent locking member. The locking member is positioned within a counterbore of each impeller when the impellers are placed on the shaft between each diffuser. After positioning, the locking member is activated to bond the impellers to the shaft. Preferably, the locking member is a heat activated material that requires heat for the material to become fluid. On cooling, the adhesive forms a rigid bond with the shaft.
