1. High-flow start-up characteristics of Sanitary Centrifugal Pump - fully open valve start-up

The shaft power of the axial flow pump is the largest at zero flow conditions, which is 140%~200% of the rated shaft power, and the power is the smallest at maximum flow. Therefore, in order to minimize the starting current, the starting characteristics of the shaft power should be large-flow start-up (i.e. fully open valve start-up).

2. Start-up characteristics of mixed flow pumps - fully open valve start-up

The shaft power of the mixed flow pump at zero flow conditions is between the above two pumps, which is 100%~130% of the rated power, so the starting characteristics of the mixed flow pump should also be between the above two pumps, and it is best to start with a fully open valve.

3. Start-up characteristics of vortex pumps - fully open valve start-up

The shaft power of the vortex pump is the largest at zero flow conditions, which is 130%~190% of the rated shaft power. Therefore, similar to the axial flow pump, the starting characteristics of the vortex pump should be large-flow start-up (i.e. fully open valve start-up).
