PURPOSE: A pump is provided to simplify maintenance and repair by easily moving a pump to a repair spot and repairing and simply assembling the pump. CONSTITUTION: A pump includes a housing (210), a motor, an impeller, a guide member, a valve (241) and an elastic member. A plurality of support ribs are extensively formed in the central side of an inlet hole in an inner surface of the inlet hole formed in the housing. A support pipe in which a support rod is inserted and supported is protruded parallel with the support rod in a guide member side which is the inner side of the housing an end unit of the support rib located in the central side of the inlet hole. One cross-section of the support pipe is located inside the housing and the other cross-section is located inside of the inlet hole. The support rod performs a straight-lined reciprocal motion within the support pipe. The body has an outer frame, a first protruded pipe, a middle frame, a second protruded pipe and an inner plate. The first protruded plate is protruded from the inner surface of the outer frame to the inlet hole side. The middle frame is protruded from an end unit of the first protruded pipe to the central side of the first protruded pipe. The second protruded pipe is protruded from the inner surface of the middle frame to the guide member side. The inner plate is formed in an end unit of the second protruded pipe. |
