Structural characteristics of single-stage centrifugal pump

The single-stage centrifugal pump is characterized in that it also includes a wafer coupling arranged between the output shaft of the motor and the pump shaft, and a guide bearing mounted on the bearing seat to assist in supporting the pump shaft; the wafer coupling is provided. The shaft device is rigidly connected with the motor output shaft and the pump shaft respectively, and a space distance is left between the motor output shaft and the pump shaft to facilitate the assembly and disassembly of the mechanical seal and the mechanical seal gland. When repairing or replacing the mechanical seal, it is not necessary to remove the motor and pump cover.
