WebDec 17, 2011 · One of the advantages of positive displacement pumps is their ability to self-prime under suction lift conditions. Air-operated diaphragm and peristaltic pumps, for example, can self-prime up to as much as 20 feet of lift, while controlled volume metering pumps are usually limited to 3 to 5 feet. WebFeb 1, 2010 · Positive displacement pumps are actually more efficient at higher viscosities C. Flowrate versus viscosity — Centrifugal pumps lose flow as viscosity increases, while the flow of a PD pump can actually increase at higher viscosities D. Efficiency versus pressure — Changes in pressure have minimal effect on PD pumps, but have a dramatic effect on …
WebPositive displacement pumps are less able to handle low viscosity fluids than centrifugal pumps. To generate suction and reduce slippage and leaks, a rotary pump relies on the seal between its rotating elements and the …
