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.

Under Construction

The plan is to put together a video and post it here that shows how the data taken during the pump test in the video above can be plotted and interpreted on the pump's curve.
