5)
Machine type:
Multi-stage vertical semi-axial pump with inducer.

Application:
Water transport pump, pump in process industry.

Project extent:
Determination of causes for insufficient suction capability of the pump.
Preposition of inducer and suction impeller modification in order to improve suction capability of the pump.

Main goals:
Achieve the desired cavitation characteristics of the pump.
