LG,

Please clarify what you are looking for.

You state your DE filter pump has stopped.
A DE Filter is not a pump. It is the filtration for your system
Your pump draws the water from your pool and circulates the water through your filter.
A salt chlorine generator is a sanitizing system that replaces the need to add chlorine manually, as you will be producing your own.
There are several posts here that compares salt systems, describes benefits to salt systems and also describes what is involved to salt pool ownership.

There is another pool owner based site that you can read other reviews.

If you have any specific questions about salt systems after you have reviewed the other posts, let me know and I can help.
