ABSTRACT:
A pump unit is disclosed which is used in feeding liquid in pipe line. The unit comprises a motor section and a pump section axially coupled with each other. The pump section includes a volute casing in which an impeller is rotatably mounted on an extended shaft of the motor and a cover plate having suctioning opening is attached to the volute casing in such a manner that it is radially adjustable to the casing at the time of installation, whereby the alignment of the suctioning opening with the impeller is made easy. The construction of the casings and parts related thereto are designed so that the elements involved are possible to be produced out of sheet metal stock. Further, the air ventilation system of the motor section is designed so as to prevent the entrance of liquid, rain or water droplets into the inside of the motor.
