There’s often much confusion in today’s general manufacturing space about the true nature of positive displacement pumps. In fact, PD pumps are frequently lumped together with centrifugal pumps, which further muddies the waters in terms of how PD pumps work, their real-world value proposition, and which industries or applications are the best fit to maximize performance.
The good news for you is that the confusion, conflation, and chaos around positive displacement pumps ends here. Today. With this very blog entry. We’ll start with a simple, workable definition. PD pumps trap fixed amounts of fluid within the system to create a constant, consistent flowrate that is independent of pressure. Additionally, because of this consistent nature of fluid movement, PD pumps are a mission-critical tool for environments where high-degrees of dosing accuracy is key.
