ZX series and ZW series self-priming pumps are the two types of commonly used self-priming pumps. They have a compact design, high efficiency and energy saving, strong discharging capacity, easy maintenance and good self-priming. They are available in cast iron and stainless steel, you can choose according to your needs. However, how to distinguish between a ZX series self-priming centrifugal pump and a ZW series self-priming sewage pump? Next, we will take you to understand it in detail.
1. Difference of materials to be conveyed
ZX series self-priming pump is mainly used for conveying clear water or medium similar to clear water, while ZW series self-priming sewage pump is used for conveying material containing material with impurities, such as sewage.
2. Impeller difference
The ZW self-priming sewage pump and ZX self-priming pump have quite different impellers. The ZW self-priming pump's impeller is partially open, whereas the ZX self-priming pump's impeller is completely closed. Because the ZW self-priming sewage pump has a unique impeller and pump body structure that allows it to pass through longer fibers and larger particles, it can be utilized without the need for a bottom valve, unlike other self-priming pumps. ZW self-priming sewage pump is also known as a solid-liquid pump or impurity pump. This pump series has a unique hydraulic construction, the impeller is shrunk in a separate impeller chamber, and the pressure water chamber is connected to the impeller chamber. The liquid inside the pump creates a powerful axial vortex effect while the impeller rotates, creating head at the outlet and vacuum at the input. Its sewage effect is superior to that of other self-priming sewage pumps because contaminants can be released from the pressure water chamber, allowing for a completely unobstructed flow path.
3. Different application scope
ZW self-priming sewage pumps can be widely used in municipal sewage engineering, food, light industry, papermaking, mining, petroleum, textiles, river and pond breeding, and other industries. And this machine is the ideal impurity pump for handling solid particles, slurry, fibers and mixed suspended media. The ZW series electric self-priming pump has the advantages of compact structure, easy operation, smooth running, easy maintenance, high efficiency, long service life and strong self-priming ability. Simultaneously, the pipeline does not need to install the bottom valve, before work. This is done merely to guarantee that the quantitative priming liquid stored in the pump body may be used, which will simplify the pipeline system and enhance working conditions. ZX self-priming pumps are available for urban environmental protection, construction, fire fighting, the chemical industry, pharmaceuticals, printing and dyeing, brewing, electric power, electroplating, papermaking, equipment cooling and other fields. It can also be sprayed by scattering water into tiny raindrops after rushing it into the air, which is good equipment for farms, nurseries, orchards and tea gardens.
In summary, the primary distinction between the ZW and ZX self-priming sewage pumps is the medium to be delivered, the impeller, and the range of applications. As a result, when choosing the type, we must consider the actual working conditions. If you have any queries, please contact our professional staff. Just click to get selection help!
