Cap Start/Induction Run vs Cap Start/Cap Run
Cap Start/Induction Run vs Cap Start/Cap Run
(OP)
I was recommended to replace my old control box (for submersible pump) which was capacitor start/induction run with capacitor start/capacitor run one. Will somebody please explain to me the pro and con on both winding.

Check out page 15+ for descriptions, and a chart on page 26 boils it down.
This one has additional information specific to pump motors.

Siamterm:
For submersible pump motors the voltage drop in the power supplying cables must be kept to a minimum. For that reason a "Capacitor start - Capacitor run motor" is very convenient due to the improved Power Factor and resultant reduction in line current.
