Positive Displacement (PD) Pumps Market - Global Industry Size, Market Share, Trends Analysis, And Forecast, 2012 - 2018
PD pumps (Positive displacement pumps) are pumps which displace or disperse fluids at a constant rate and volume. The positive displacement market faces a constant competition from the centrifugal pumps market.

These pumps are majorly used because of their ability to exhibit high performance in dealing with fluids with high viscosities and their ability to handle pressure changes.
