ABSTRACT: In an industry that
uses large centrifugal pumps continuously, pump speed setting can reduce energy
consumption significantly. By changing the speed of a centrifugal pump, capacity, head, and pump power required will
change according to pump affinity laws. Speed of a centrifugal pump can be
changed by variable frequency drive .
This study aimed to investigate the characteristics of mixed flow centrifugal
pumps with variable frequency drive. The results showed that 10% of maximum
speed reduction can decrease power consumtion until 50%, while the increase in
the efficiency is maximum 7.2%. The power reduction is different for different
speed reduction. In a dynamic head dominated system the efficiency will remain
constant during speed reduction while in static head dominated system will
change.
