To save energy, some multi-stage pumps adopt measures to reduce the number of impellers. What factors should be considered when reducing the number of impellers in a multi-stage pump, and how should this reduction be carried out?
Based on the head you need, subtract that amount after conducting the dynamic balance test. A single stage can also be used to cut the impeller in order to save energy
A range of factors such as your head, flow rate, axial force balance, and rotor balance all need to be taken into consideration; it is recommended that the manufacturer carry out the calculations and modifications.
