High suction self-priming sewage pump

Application of open impeller self-priming sewage pump

1. 1. Water supply and drainage for industrial and mining enterprises.

2. 2. Used for water supply and drainage in construction projects.

3. 3. Used for agricultural irrigation and drainage.

4. 4. Used for drainage in sewers and purification tanks.

5. 5. Wastewater transportation in sewage treatment plants.

High suction self-priming sewage pumpfeature

1. High efficiency, small size, light weight, no space occupation, easy installation.

1. 2. Using mechanical shaft seals to ensure no water leakage, no damage to the shaft axis, no trouble with cotton yarn insertion, and extended service life.

2. 3. The special structure of the body has high self-priming ability.

3. 4. The impeller adopts a semi open design, which has strong conveying capacity for sewage and debris.

4. 5. As long as the water is added for the first operation, the trouble of watering in the future can be avoided.

High suction self-priming sewage pumpUsage steps:

1. Before use, check whether the rotation direction of the pump is correct and whether it rotates flexibly.

2. Unscrew the liquid filling plug above the pump body of the self-priming unobstructed sewage pump, fill the reservoir, and then tighten the plug. In the future, there will be no need to refill the reservoir when starting up. The pump should not be started and operated when there is insufficient liquid storage, otherwise the pump cannot work properly and the mechanical seal may be damaged.

3. When starting the self-priming sewage pump, the outlet flow control valve should be opened first to facilitate the discharge of gas during the self-priming process. After starting, adjust the opening of the outlet flow control valve to ensure that the pressure gauge reading is within the specified range (various pump type pressure control range tables), avoiding the pump from working within the lower limit of the specified range, to prevent motor overload and burnout caused by excessive shaft power or cavitation caused by excessive flow, affecting the normal operation of the pump and causing strong vibration and noise.

4. During operation, the temperature rise of the pump and motor should be checked regularly. If noise or other abnormal sounds are found, the machine should be stopped for inspection and troubleshooting before resuming operation.

5. When shutting down, the outlet flow control valve should be closed first before shutting down to avoid insufficient liquid storage in the pump due to siphon effect.

6. Regularly refuel and maintain the pump. If it is not used for a long time, the pump should be disassembled, cleaned, and oiled, and stored properly.
