PURPOSE: A pump assembly is provided to perform maintenance and repair after pulling up internal components of a pump, thereby remarkably reducing costs as an assembly of an impeller and a rotary shaft is pulled up during initial installation states of a column pipe and a suction pipe are maintained. CONSTITUTION: A pump assembly comprises a column unit assembly, a pumping unit assembly, a rotary shaft supporting member(140), and a discharging pipe(400). The column unit assembly is composed of a connection pipe(230), a suction pipe(220), and a column pipe(210). The connection member includes an outlet(232) discharging waste water to the discharging pipe in one side. The waste water flows in through the suction pipe. The column pipe connects the connection member and the suction pipe. The pumping unit assembly discharges the waste water to the discharging pipe by rotating a motor(110) and a rotary shaft(120) inside the column unit assembly. The rotary shaft supporting member supports the rotary shaft to be rotatable inside, and the outer circumference of the rotary shaft supporting member is joined to be slid in and out on the inner circumference of the column pipe. The discharging pipe is joined to the outlet formed in one side of the connection member. The pumping unit assembly is joined to or separated from the column unit assembly by joining or separating a joining member(500) which joins or separates the motor and the connection member. |
