Centrifugal pump - Wikipedia

A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts. At each stage, the fluid is directed to the center before making its way to the discharge on the outer diameter....<<more>>

Centrifugal Pump Efficiency ~ ME Mechanical

Mechanical efficiency of a centrifugal pump (η m) is the ratio of theoretical power that must be supplied to operate the pump to the actual power delivered to the pump. Mechanical efficiency can be used to determine the power loss in bearings and other moving parts of a centrifugal pump....<<more>>

Pump efficiency | KSB

For centrifugal pumps whose mechanical design does not clearly separate the pump shaft from the drive shaft, such as is the case with close-coupled pumps and submersible motor pumps, the efficiency of the pump set (η Gr) is specified in place of pump efficiency (see DIN 24 260) (Gr stands for group)....<<more>>

Pump ED 101

The overall efficiency of a centrifugal pump is simply the ratio of the water (output) power to the shaft (input) power and is illustrated by the equation below. η = P W / P S where η is efficiency, P w is the water power, and P s is the shaft power....<<more>>

Centrifugal Pump Efficiency Calculation - Chemical

Centrifugal pump efficiency is the ratio of Hydraulic power delivered by the pump to the brake horsepower supplied to the pump. Hydraulic Power (Power Output from Pump): Centrifugal Pump consumes energy to develop the discharge pressure and to deliver flow....<<more>>
