Because the problem of the failure state of used centrifugal pump impellers is uncertain， and the remanufacturability evaluation also focuses on the remanufacturing process and qualitative evaluation， a remanufacturability evaluation method of centrifugal pump impellers for re-service performance is proposed. This method integrates the whole process of centrifugal pump impeller remanufacturing to re-service, establishes the corresponding evaluation index system from three aspects of technical feasibility， economic feasibility(considering remanufacturing cost and remanufacturing cycle)， and re-service performance of remanufactured centrifugal pump impellers， and conducts qualitative or quantitative analysis. The remanufacturability evaluation method was verified and analyzed through the remanufacturing process of a certain type of impeller. The remanufacturability evaluation method has good practicability， is conducive to ensuring the service safety of remanufactured impellers， and provides a decision-making tool for the implementation of waste impeller remanufacturing.
