Upgrading instead of replacing can be a practical solution to improve motor reliability.
Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
