Positive Displacement Pumps Are

Positive displacement pumps are the pumps that provide flow and pressure to the outside, which are conventional pumps. A negative displacement pump is a hydraulic motor that runs on external pressure and flow. Positive displacement pumps are self-charging. Unlike centrifugal or turbo pumps, flow is constant regardless of system pressure
