KEERTHI MF series – Mixed Flow Pumps are single‐stage centrifugal pumps suitable for handling pure or contaminated liquids in large volumes. The energy efficient and reliable MF series mixed flow pumps function as a compromise between radial and axial flow pumps. They operate at higher pressures than axial flow pumps while delivering higher capacities. The pumps are available in both horizontal and vertical configurations.
