The self-balancing multi-stage pump uses an advanced modular design that uses a large number of long-running partial components for high interchangeability. High-strength, high-quality materials and a wide selection of inlet and outlet flanges and adapter designs increase the pump's high allowable nozzle load. High-strength, high-quality pump housing construction materials have a tight service life five times that of ordinary castings. The impeller and guide vane of the over-flow part are precision cast, and the smoothing and flatness is more than 2% higher than that of the ordinary casting. The specific requirements of the system under special circumstances of the user can be met at any time.
1. Flatten a clean cloth, plastic film or wooden board and place the removed inner magnetic rotor part vertically on the cloth or wooden board. The impeller is above and the inner magnetic rotor contacts the cloth or wood board.
2. Determine the direction of the impeller according to the direction of rotation, and then determine the direction of the impeller nut. Remove the impeller nut.
3. Pull the impeller out.
4. Remove the front thrust plate.
5. Pull out the pump cover and take care when pulling out the pump cover to prevent the sliding bearing from slipping out of the pump cover.
6. Place the pump cover on the ground, take out the front end sliding bearing, then turn the pump cover over, place it on the ground, and take out the rear end sliding bearing.
7. Remove the bushing and bushing positioning sleeve.
8. Remove the rear thrust plate.
9. Remove the rotor from the pump shaft.
