Mixflow
Mixed-flow hydraulics move higher water volume at moderate head. They are commonly suited to general borewell irrigation where discharge is the priority.
K-Type
K-Type hydraulics provide higher head per stage with lower discharge. They suit deeper bores where lifting water is more important than maximum volume.
Make the final selection
Use operating water level, total lift, delivery pipe, desired discharge, HP, and stage count together. Ask for a model recommendation when the bore data is incomplete.
