Abstract
An electric water pump, and more specifically an electric water pump having an improved wet sleeve so that the water pump is free of a housing. The electric water includes a pump rotor having a shaft. A wetsleeve surrounds the rotor and has a cap, a sleeve that houses the rotor, and a seat in communication with the shaft of the rotor so that the seat assists in supporting the shaft a stator. Surrounding the wet sleeve and the rotor is a volute covering an upper portion of the rotor, wet sleeve, and stator. The electric water pump further includes a rubber boot covering a lower portion of the rotor, wet sleeve, and stator and is in communication with the volute forming a cover.
