When to use a Positive Displacement Pump
When to use a Positive Displacement Pump When to use a centrifugal or a Positive Displacement pump ( PD Pump ) is not always a clear choice. To make a good choice between these pump types it is important to understand that these two types of pumps behave very differently. Flow rate versus pressure By looking at the performance chart to the ryou can see just how different these pumpare. The centrifugal has varying flow depending on pressure or head, whereas the PD pump has more or less constant flow regardless of pressure. ight s ate chart how the centrifugal pump only the e fficiency versus pressure n By e Performance050100150200250050100150 Capacity GPMHead FeetPositive Centrifugal Flow rate versus viscosity Another major difference between the pump types is the effect viscosity has on the capacity of the pump.
