Abstract
Of the components making up the pump, one part including the bearing is removably assembled into the other part so that the bearing is received in the other part. This structure allows easy removal of the first part of the pump components from the second part for disassembly and for maintenance and inspection of the pump. The pump can also be reassembled with ease by inserting the first part into the other part.
