ZW non-clogging sewage pump, explosion-proof submersible sewage pump, pipeline sewage pump

1. Overview of ZW self-priming non-clogging sewage pump

Compared with similar domestic products, the self-priming non-clogging sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, convenient use and maintenance, etc. It belongs to the domestic leading level in the non-clogging sewage pump series products. Its various technical performance indicators rank among the top in China, reaching the international advanced level, and it has broad application market and development prospects. The ZW self-priming sewage pump is a novel structure product developed on the basis of repeated research on similar technologies at home and abroad. The ZW self-priming sewage pump integrates self-priming and non-clogging sewage discharge, adopts axial reflux external mixing type, and through the design of the pump body and impeller flow channel, it can not only install bottom valves and fill water like ordinary self-priming clean water pumps, but also suck and discharge liquids containing large particles and long fiber impurities. It is an ideal impurity pump for chemical media such as municipal sewage engineering, river pond aquaculture, light industry, papermaking, textile, food, chemical industry, electric power, fiber, pulp and mixed suspension.

2. Scope of application of ZW self-priming non-clogging sewage pump:

Compared with similar domestic products, ZW self-priming sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, convenient use and maintenance, etc. It ranks among the top in domestic sewage pump series products. Its various technical performance indicators lead the domestic market, reaching the international advanced level, and it has broad application market and development prospects.

4. Characteristics of ZW self-priming sewage pump

ZW non-clogging self-priming sewage pump is mainly divided into two types: ZW type with coupling and ZWL type without coupling direct connection. ZW self-priming sewage pump is an earlier type of self-priming sewage pump product. The ZW self-priming sewage pump with coupling has certain advantages for transporting high-temperature liquids: it will not transfer heat to the motor due to high liquid temperature, and will not cause motor water ingress after mechanical seal leakage. The advantage of ZWL self-priming sewage pump is small floor area, low vibration and noise. It adopts direct connection type, which avoids the disadvantage of balancing required for coupling type, with reliable operation and low failure rate. The self-priming height of ordinary self-priming sewage pump is within 5 meters. If you need a self-priming sewage pump with better self-priming height, you can consult us. We can customize various high-lift self-priming sewage pumps according to actual needs. We can also customize vacuum-assisted self-priming sewage pumps for both ZW self-priming sewage pumps and ZWL self-priming sewage pumps to meet the defect of insufficient self-priming height.
