A wet motor pump has an armature located in a motor chamber. A shaft bushing with an internal bore rotatably supporting a shaft end portion of an armature shaft is located in an outlet housing having a bore and a bushing support for receiving the shaft bushing. The bushing, end portion of the armature shaft, the internal bore as well as an end wall passage of the outlet housing structure defines an end chamber wherein are provided an end chamber inlet passage and an end chamber outlet passage for communicating the end wall passage and the wet motor chamber. A pressure differential structure establishes a pressure differential between the end chamber inlet passage and the end chamber outlet passage, to cause a fluid flow into the end chamber inlet passage, to cool and lubricate the shaft bushing, and therefrom out of the end chamber outlet passage forming a cooling and lubrication system.
