How does a bilge system work?

A bilge system's function is to remove water from the hull of a boat. The systems consist of pumps, motors to run the pumps, piping, and control. The pumps are normally centrifugal type pumps, though any could be used as long as the pressure and flow rate are sufficient to drain the hull. Motors are normally electric driven off of a battery or alternator from the main engine, and can be controlled automatically in the event of an emergency or manually.
