Positive displacement pump curves give you the information you need to determine a pump's ability to produce flow under the conditions that affect pump performance. PD pumps come in a variety of mechanical designs, to name a few: Circumferential Piston Pumps Rotary Lobe Pumps Twin-Screw Pumps ...
Changes in pressure differential have little impact on the flow rate of positive-displacement pumps compared to centrifugal pumps when pumping viscous product. Disadvantages In comparison to other types of pumps, however, twin screw pumps have a couple of disadvantages: Twin screw pumps are relati...
