The post-evaluating indexes of pump performances of large low-lift pumps in the Eastern Route of the South-to-North Water Diversion Project in first stage were put forward, which would help progress with high quality and standard in purchasing, supervising, installation and ac-ceptance check of pump. The efficiency and the values of vibration and noise of pump set should be post-evaluated. Based on the production of model pump test in the same test-bed for the South-to-North Water Transfer Project and related codes and specifications,the indexes were put for-ward. Ultrasonic flowmeter set in inlet passage was suggested to test flow of pump. The vibration of stators of pump set should use vibration ve-locity sensors. The test error of efficiency of pump should not exceed ±2.0%.
