Claims

[Scope of utility model registration request]

Two submersible pumps la and lb are removably accommodated in the pump tank 2 so as to share a single drain pipe 9, and each of the pump discharge ports 3a and 3b of these two submersible pumps la and 1b is Check valves 1la and llb are formed at the connecting portion 10, the mouth end of which is separably opposed to the conduction chamber 9' formed at the end of the drain pipe 9, and are used to prevent backflow when the pump is stopped. The two submersible pumps la and lb are attached to the respective pump discharge ports 3a and 3b, and are operated alternately at predetermined time intervals when the connecting portion 10e is connected.
If necessary, the two submersible pumps 1aib are electrically connected so that they can be operated simultaneously, and when one submersible pump 1a is in operation, the check valve 11a is opened so that the pump discharge port 3a communicates with the communication chamber 9'. When the other submersible pump 1b is operated, the check valve 11b is opened so that the pump discharge port 3b communicates with the communication chamber 9',
The outer wall of the pump tank 2 is provided with an inlet 6 that communicates with each pump suction port 4a, 4b of the two submersible pumps 1aib+ through the inside of the pump tank 2, and an inlet 6 that communicates with each pump suction port 4a, 4b of the two submersible pumps 1aib+ through the inside of the pump tank 2. A drainage unit having a discharge port 8 communicating with each pump discharge port 3at3b in the submersible pumps 1a and lb.
