Google control wire diagram of start and stop a function

i have faced a problem in ro plant grunfos make bm30type pump it is 22kw pump. We start this pump using siemens 3rw 4423-ibc44, 30kw softstarter but this soft starter will frequently failier so we planed to change dol starter. So pls tell anybudy its possible or not.
