A submersible mixed flow pump is a rotodynamic pump where fluid enters the impeller axially and is discharged at an angle between axial and radial. This hydraulic design purposefully blends the characteristics of axial and centrifugal flow patterns, creating a balanced solution that maintains high hydraulic efficiency in the moderate head range. According to a Pumps & Systems article analysing these pump types, “mixed-flow pumps offer the ideal solution for applications where the head requirements are too high for an axial flow pump but the flow rates are too large for a traditional centrifugal pump” (source: Mixed-Flow Pumps Bridge the Gap).
