Is the shaft power of a centrifugal pump the same as that of the motor?
Motor power specificationRelationship between pump shaft power and motor power0.75-2.2KW 1.2-1.4 times, 3.0-7.5KW times 1.15-1.25 times, 11KW times 1.1-1.15 times, and according to national standard Y series motor power specifications.
Centrifugal pump shaft power and motor power is not the same.Pump shaft power is the original motivation to design on the pump power, during the actual operation, the operating point will change, so the original motivation to pump power should have a certain margin, the other motor output power due to power factor, so the experience is equipped with motor power is greater than the pump shaft power.
Motor power selection and estimation of centrifugal pumps0.12-0.55kw 1.3-1.5 times 0.75-2.2kw, 1.2-1.4 times, 3.0-7.5, kW, 1.15-1.25 times, more than 11 times 1.1-1.15 times kW, and according to national standard Y series motor power specifications matching.
