ZW stainless steel explosion-proof self-priming sewage pump, ZW 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, and convenient use and maintenance. They are among the top domestic products in the non-clogging sewage pump series. Various technical performance indicators rank among the top domestic ones, reaching international advanced level, and have broad application markets and development prospects. ZW self-priming sewage pump is a structurally innovative product developed on the basis of repeated research on similar technologies at home and abroad. 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 priming water like ordinary self-priming clean water pumps, but also suck and discharge liquids containing large particles of solid matter 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.

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 water. The advantage of ZWL self-priming sewage pump is that it covers a small area, with low vibration and noise. Since the direct connection type is adopted, the disadvantage of the coupling type that needs dynamic balance adjustment is avoided, so the operation is reliable and the failure rate is low. The self-priming height of ordinary self-priming sewage pumps 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. 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 problem of insufficient self-priming height.
