A wet rotor-type pump, in particular used for pumping a coolant in vehicle motors, comprises a pump impeller (10) for feeding a fluid and a motor rotor (22,24) connected with said pump impeller (10). In wet rotor-type pumps the motor rotor is cooled by the fluid to be pumped. For protecting the motor rotor (22,24) against corrosion, the latter is, according to the invention, surrounded by a protective means comprising a ring-shaped hollow space (20). In said hollow space (20) the motor rotor (22,24) is received.
