Replacing an Oversized and Underloaded Electric Motor

Replacing an Oversized and Underloaded Electric Motor

Many energy-efficient motors tend to operate with a reduced full-load slip or at a slightly higher speed than their standard efficiency counterparts. This small difference can be significant. For centrifugal fans and pumps, even a minor change in the motor ’s operating speed translates into a significant

Back to Basics: How to Increase Pump Motor Efficiency ...

Nov 01, 2011 Most pumps are driven by induction motors, which means that motors contribute to the overall pumping system efficiency. This column is dedicated to exploring the key motor efficiency issues that are under the pump user’s control. In a typical industrial site, motor driven equipment accounts for two thirds of the electric energy consumed.

Calculation of Pump Efficiency: Formula Equation Linquip

Sep 16, 2021 Two simple but highly efficient machines are used a lot in the pump industry: centrifugal pumps and AC induction motors. Centrifugal pumps turn mechanical energy into hydraulic energy (flow, pressure, and velocity), and AC motors convert electrical energy into mechanical energy. Most medium and larger centrifugal pumps have efficiencies in the ...

Bearings in centrifugal pumps - SKF

The centrifugal pump impeller is most typically supported on its own shaft and bearings and driven by an electric motor, and less often by an engine or a turbine. The pump shaft is connected to the driver either directly through a flexible coupling or indirectly by a belt drive. The impeller can also be rigidly connected to the motor shaft ...

the most efficient pump, even if it requires higher initial outlay. Replacing incorrectly sized motors or pumps can often have a quick payback. The efficiencies of both the pump itself and the motor are combined for overall efficiency. So, for example, a 90% efficient motor on a 70% efficient pump is only 63% efficient overall ( 0.9 x 0.7 = 0.63 ).

How to Size an Electric Motor for Use with a Centrifugal Pump

How to Size an Electric Motor for Use with a Centrifugal Pump

The power required to drive the pump at the rated design condition should always be less than the nameplate horsepower rating of the motor. So if the pump will require 4.5 HP at the design condition, at a minimum, the motor should be sized for 5 HP – the next nominal size above 4.5 HP. In many cases, it will make sense to select a motor large ...
