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.

Compare and Contrast: conventional flow control valve vs. an Equilibar regulator

Equilibar’s direct-sealing diaphragm technology was first introduced to provide precise backpressure control for complex applications; however, engineers and scientists soon discovered that these devices can offer advantages for extremely complex flow control applications as well. Specifically, they perform well in applications involving wide flow rate ranges, corrosive chemicals, extreme pressures, multi-phase flows and supercritical states. Read More
