Using a basement sump pump is like using an automobile airbag; you hope you do not ever have to use it. If you do need it, it can be a real live saver. A home sump pump can be of either manual or automatic type. Battery operated sump pumps are available as well.

If you have a wet basement problem as a usual thing, you probably already have an automatic sump pump in place. If you only occasionally have this issue, you may be able to get by with a manual type sump pump that you operate as needed. Either type will do the job. Both require safe installation and operation as well. For safety and for the protection of your investment, it is best to have your sump pump installed and inspected by a plumbing professional.
