Hello,
Tecnically it's possible to use a VFC for controlling a linear motor pump with power factor 0,08, but I would like to know if someone have experiens of this kind of application. Motor is 700 A meaning hence the current drawn from the supply net is about 70A. The magnetizing current is huge.

mosse,
your power factor seems to be too low for a three-phase motor.
Can you give more details, like nominal voltage and frequency?
Best regards

I have not done it, but it should be able to be done.
Your pf does seem very low!!
Best regards,
