Single-stage pump

Single-stage pump is the only one impeller of the pump, the general single-stage pump head is only about 100 meters. The utility model has the advantages of simple structure, stable performance, high speed, small size, light weight, high efficiency, large flow rate, easy operation and maintenance, etc.. In accordance with the installation position of the motor is divided into: Horizontal single-stage pump, vertical single-stage pump. The typical Horizontal single-stage pump is IS type, IR type, IY type, vertical single-stage pump is represented by ISG. According to the suction channel can be divided into: single suction centrifugal pump, single-stage double suction centrifugal pump. Single stage single suction centrifugal pump is represented by IS, single stage double suction centrifugal pump is represented by S. Single-stage pump pump of single-stage pump comprises a pump body, pump cover, a motor with an output shaft, the single-stage pump installed in the pump shaft, bearing, impeller, mechanical seals and sealing cover, characterized in that it also comprises a motor output shaft is arranged between the pump shaft and clamp type couplings, and mounted on the bearing seat to guide bearing auxiliary supporting shaft; the clamp coupling respectively with the output shaft of the motor shaft and the rigid connection between the motor output shaft and the pump shaft is left for mechanical seals and sealing cover installation space. In the maintenance or replacement of mechanical seal, no need to remove the motor and pump cover.
