Testing a Pump
(Plus a Demonstration of How Induction Motor Slip Varies with Load)
These videos illustrate how a centrifugal load in the form of a pump interacts with an induction motor as the load varies. In the course of the demonstration, the videos also illustrate how to perform a pump test and then assess the results.

This first video was developed by the Pacific Energy Center to support the On-Demand content on induction motor principles that can be accessed from the On Demand page of the website. In it, I vary the load that the pump sees and you an watch the motor slip and kW vary as I do it. In the course of doing that, I also illustrate the basic steps in performing a pump test. |
