Selection Guide
Positive Displacement vs. Centrifugal Pumps
-
1
Positive displacement pumps suit controlled flow, higher viscosity, and pressure-sensitive transfer.
-
2
Centrifugal pumps suit continuous movement of clean, low-viscosity liquids at stable duty points.
-
3
Final selection should be based on duty point, fluid behavior, installation conditions, and maintenance goals.
For selection, share flow rate, discharge pressure or head, viscosity, temperature, solids content and installation conditions — our engineers will recommend the right dosing configuration.
