ZW self-priming sewage pump, high-lift self-priming sewage pump

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

Compared with similar domestic products, self-priming non-clogging sewage pumps have the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, convenient use and maintenance, etc. They are among the top domestic products in the non-clogging sewage pump series. Their various technical performance indicators rank among the top in China, reaching international advanced level, and have broad application markets and development prospects. The ZW self-priming sewage pump is a structurally innovative 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 neither need to install foot valves and priming water like ordinary self-priming clean water pumps, but also can suck and discharge liquids containing large particle solids and long fiber impurities. It is an ideal impurity pump for chemical media such as municipal sewage engineering, river and pond aquaculture, light industry, papermaking, textile, food, chemical industry, electric power industry, fibers, pulp and mixed suspensions.

4. Characteristics of ZW self-priming sewage pump

ZW non-clogging self-priming sewage pumps are 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 the high liquid temperature, and will not cause the motor to be flooded when the mechanical seal leaks. The advantages of ZWL self-priming sewage pump are 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 pumps is within 5 meters. If you need self-priming sewage pumps with better self-priming height, you can consult us. We can customize various high-lift self-priming sewage pumps according to actual needs. For ZW self-priming sewage pumps and ZWL self-priming sewage pumps, we can also customize vacuum-assisted self-priming sewage pumps to solve the defect of insufficient self-priming height.
