Product details
Overview of ZX Horizontal Self priming Centrifugal Pump
The ZX series self-priming pump is an energy-saving pump product developed by absorbing, digesting, and improving relevant technical data at home and abroad. This pump belongs to the self-priming centrifugal pump, which has the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Therefore, the pipeline system has been simplified and the working conditions have been improved.
Application scope of ZX horizontal self-priming centrifugal pump
1. Self suction centrifugal pumps are suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, printing and dyeing, brewing, electricity, electroplating, papermaking, equipment cooling, etc.
2. With the rocker nozzle, the water can be washed into the air and dispersed into small raindrops for spray. It is a good machine for farms, nurseries, orchards and tea gardens.
3. Suitable for clear water, seawater, chemical media liquids with acid and alkalinity, and slurries with general paste like properties (medium viscosity and solid content up to 30% or less). Different liquids can be made of different materials. On HT200, ICR18NIGTI, OCR18NIG, OCR17Ni14M02, ICR18NI12M02TI respectively.
4. It can be used in conjunction with any type and specification of filter press, and is an ideal pump for delivering slurry to the filter press for pressure filtration.

Cause and solution of malfunction
| Fault phenomenon | cause analysis | Troubleshooting |
| ZX self-priming centrifugal pump does not produce water | 1. There is no liquid storage or insufficient liquid storage inside the pump casing 2. Air leakage in the suction pipeline 3. The speed is too low 4. The suction stroke is too high or the suction pipeline is too long 5. Excessive leakage of mechanical seal 6. The gas in the suction pipeline cannot be discharged from the outlet |
1. Add sufficient fluid storage 2. Check and eliminate any air leaks 3. Adjust the speed 4. Reduce the suction stroke or shorten the suction pipeline 5. Repair or replace 6. Discharge it |
| ZX self-priming centrifugal pump has significant noise and vibration | 1. Unstable footing 2. Bending of pump shaft 3. Cavitation phenomenon 4. Severe bearing wear 5. There are impurities in the imported pipeline 6. The main shafts of the pump and motor are not concentric |
1. Reinforcement 2. Replace or calibrate 3. Adjust the working conditions 4. Replace 5. Remove debris 6. Adjust coaxiality |
| Insufficient water output of ZX self-priming centrifugal pump | 1. The impeller passage and suction pipe are blocked 2. The impeller or impeller seal is severely worn 3. Insufficient power or too low speed |
1. Remove blockages 2. Replace the mouth ring 3. Increase power and adjust to rated speed |
| Excessive power consumption of ZX self-priming centrifugal pump shaft | 1. Excessive traffic 2. The speed is too high 3. Bending of pump shaft or collision of impeller 4. The flow channel inside the pump is blocked or stuck |
1. Increase the outlet pressure 2. Reduce appropriately 3. Replace or calibrate 4. Queue congestion |
