1. Overview of ZH stainless steel self-priming pump
ZH temperature-resistant and corrosion-resistant self-priming chemical centrifugal pump is a single-stage single-suction self-priming chemical centrifugal pump developed by our factory in combination with similar products at home and abroad. For corrosive media with particles less than 3 mm, if the conveying medium contains particles or fibers above 3 mm, you can choose the ZW non-clogging self-priming sewage pump produced by our factory. According to the different conveying media, the materials of ZH type chemical centrifugal pump contacting liquid parts can be made of cast iron, cast steel, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 316, 316L and other materials. ZH chemical pump has the advantages of high efficiency, good performance, low energy consumption and low noise.
2. Application scope of ZH stainless steel horizontal self-priming pump
ZH self-priming pump is suitable for urban environmental protection, construction, fire protection, chemical industry, pharmaceuticals, printing and dyeing, brewing, electric power, electroplating, papermaking, equipment cooling, etc.
The ZH self-priming pump is equipped with a rocker-type spray head, and the water can be flushed into the air and scattered into fine raindrops for spraying. It is a good machine tool for farms, nurseries, orchards, and tea gardens.
ZH series self-priming pump products can also be made into stainless steel self-priming pumps, which are suitable for clean water, seawater, chemical medium liquids with acid and alkalinity, and slurry medium with general paste. The viscosity and solid content can reach Below 30%. Different liquids can use different materials. Respectively in ht200, icr18nigti, ocr18nig, ocr17ni14m02, icr18ni12m02ti.
If it is made into a sewage type non-clogging self-priming sewage pump, it can also be used with any type and specification of the filter press. It is an ideal matching pump for sending the slurry to the filter press for press filtration.

5. ZH self-priming pump failure causes and solutions
Fault phenomenon | Cause Analysis | Method of exclusion |
Self-priming centrifugal pump does not produce water | 1. There is no liquid or insufficient liquid in the pump casing 2. Suction pipeline leaks 3. The speed is too low 4. The suction lift is too high or the suction line is too long 5. Excessive leakage of mechanical seal 6. The gas in the suction line cannot be discharged from the outlet | 1. Add enough stock solution 2. Check and eliminate air leakage 3. Adjust the speed 4. Reduce the suction lift or shorten the suction pipeline 5. Repair or replace 6. Make it out |
Self-priming centrifugal pump has a lot of noise and vibration | 1. Unsteady feet 2. The pump shaft is bent 3. Cavitation phenomenon 4. The bearing is seriously worn 5. There are sundries in the inlet pipeline 6. The main shafts of the pump and the motor are not concentric | 1. Reinforcement 2. Replace or correct 3. Adjust working conditions 4. Replacement 5. Remove debris 6. Adjust the coaxiality |
Insufficient water output of self-priming centrifugal pump | 1. The flow channel of the impeller and the suction pipe are blocked 2. The impeller or impeller seal is seriously worn 3. Insufficient power or too low speed | 1. Remove blockage 2. Replace the mouth ring 3. Add sufficient power and adjust to the rated speed |
Self-priming centrifugal pump shaft power consumption is too large | 1. Excessive traffic 2. The speed is too high 3. The pump shaft is bent or the impeller is stuck 4. The flow channel in the pump is blocked or stuck | 1. Increase outlet pressure 2. Appropriately reduce 3. Replace or correct 4. Queuing blockages |
