This unit has been designed to experience with the main equations correlating power, head, number of r.p.m. and flow rate of a centrifugal pump and to show the advantages of operating in series and in parallel.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Performance of the pump according to the following parameters:
– head
– power absorbed by the motor
– number of revolutions
• Operations in series, in parallel and with only one pump
