Product details

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 based on similar products at home and abroad. ZH pump is suitable for conveying corrosive media with a temperature of 0 ℃~220 ℃ and solid particles less than 3 millimeters. If the conveying medium contains particles or fibers of more than 3 millimeters, our factory's ZW non clogging self-priming sewage pump can be used. According to the different media being transported, the materials for the liquid contact section of ZH type chemical centrifugal pumps can be made of cast iron, cast steel, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 316, 316L and other materials. ZH chemical pumps have the advantages of high efficiency, good performance, low energy consumption, and low noise.

2、 Application scope of ZH stainless steel horizontal self-priming pump

1. ZH self-priming pumps are suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, printing and dyeing, brewing, electricity, electroplating, papermaking, equipment cooling, etc.
2. The ZH self-priming pump is equipped with a rocker nozzle, which can wash water into the air and then disperse it into small raindrops for spray. It is a good machine for farms, nurseries, orchards and tea gardens.
3. The ZH series self-priming pump products can also be made into stainless steel self-priming pumps, suitable for clean water, seawater, chemical media liquids with acid and alkalinity, and slurry media with general paste viscosity and solid content up to 30% or less. Different liquids can be made of different materials. On HT200 icr18nigti、ocr18nig、ocr17ni14m02、icr18ni12m02ti。
4. If made into a sewage type non clogging self-priming sewage pump, it can also be used with any type and specification of filter press, making it an ideal matching pump for sending slurry to the filter press for pressure filtration.

5、 Reasons and Solutions for ZH Self priming Pump Malfunctions

Fault phenomenon	cause analysis	Troubleshooting
Self suction centrifugal pump does not produce water	1.No or insufficient liquid storage inside the pump casing 2.Air leakage in the suction pipeline 3.The speed is too low 4.The suction distance 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 suction or shorten the suction line 5.Repair or replace 6.Let it be expelled
The self-priming centrifugal pump has significant noise and vibration	1.Unstable footing 2.Pump shaft bending 3.Cavitation phenomenon 4.Severe bearing wear 5.There are impurities in the inlet pipeline 6.The main shafts of the pump and motor are not concentric	1.reinforce 2.Replace or calibrate 3.Adjust working conditions 4.replace 5.Remove debris 6.Adjust coaxiality
Insufficient water output of self-priming centrifugal pump	1.The impeller passage and suction pipe are blocked 2.Severe wear of impeller or impeller seal 3.Insufficient power or too low speed	1.Remove blockages 2.Replace the mouth ring 3.Add sufficient power and adjust to rated speed
Excessive power consumption of 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.Raise export pressure 2.Reduce appropriately 3.Replace or calibrate 4.Line blockage
