ZWL type direct connected self-priming non-clogging sewage pump

Product characteristics

ZWL type direct connected self-priming non-clogging sewage pump adopts direct connected structure compared with similar domestic production, has the characteristics of simple and compact structure, less vibration, good self-priming performance, strong sewage capacity, energy saving, convenient use and maintenance.

Product overview

ZWL type direct-connected self-priming non-clogging sewage pump is a novel product developed successfully on the basis of repeated research on similar technologies at home and abroad. ZWL type direct-connected self-priming non-blocking sewage pump set self-priming and non-blocking sewage in one, the use of axial return external mixing, and through the unique design of pump body, impeller flow channel, can be like the general self-priming clean pump does not need to install the bottom valve and irrigation water, but also can suck and drain containing large particles solid and long fiber impurities liquid. It can be widely used in municipal sewage engineering, river pond culture, light industry, paper making, textile, food, chemical industry, electricity industry, fiber, slurry and mixed suspension and other chemical media ideal impurity pump.

Compared with similar domestic products, the pump has the characteristics of simple and compact structure, less vibration, good self-priming performance, strong sewage capacity, energy saving, convenient use and maintenance. The technical performance index is higher in China, and it has broad application market and development prospect.
