    摘要: A pump has a main body. An assembling part is formed in the main body and has an assembling chamber. A mounting part is formed in the assembling chamber and has a discharging chamber. An influent hole and an effluent hole are respectively defined through an inner surface of the discharging chamber. A storage hole is defined through the assembling chamber and communicates with the effluent hole. A mounting cover is mounted on the mounting part. A motor is mounted on the main body. An impeller is located in the discharging chamber and connected with the motor. A covering assembly is mounted on the assembling part and has a storage chamber that communicates with the storage hole. When working fluid passes through the effluent hole, some of the working fluid enters the storage chamber via the storage hole, eliminating the need to additionally process the mounting cover.
