David Reed is President of Equilibar and has more than 30 years of experience in the pressure control industry. His practical videos demonstrating fluid control technology have attracted a strong following on YouTube. In this video, David explains how a BPR can be used to control the flow of a non-positive displacement pump and when an engineer should consider this option. While the video uses an Equilibar back pressure regulator to illustrate the method, almost any BPR would work in a similar fashion.
