Mutiple Stages Pumps

When you must select a multiple stages pumps the theory tells the efficiency is constant and the head is exactly the number of stages times the head of the single impeller. The reality often is different.


The Multiple stages pumps option allows you to set in the Builder the coefficients that must be applied for the correction of head and efficiency for every number of stages. When the pump is selected and the number of stages is set, the Selector will use the correct coefficients and will accordingly correct the performance curves.
