Are the impellers of all-plastic pumps and lined pumps both considered wear-prone components? What is the guaranteed lifespan?
The difference between all-plastic and lined pumps lies in the pump casing; the internal components are actually pretty similar. It is a vulnerable part with a half-year warranty.
Whether it is a vulnerable component is determined based on the pump, operating conditions, and the user organization; the warranty period is also set according to actual circumstances, with no uniform mandatory requirements
Impellers are wear-prone components; as long as they are not running idle and operate normally, their lifespan is quite long. Just replace the seal.
They are all vulnerable components; those of better quality can last for a few years, while those of lower quality break after just a few months
