I. Overview This series of non-clogging sewage pump is the introduction of foreign energy-efficient non-clogging sewage pump and the development of domestic technical force made, the performance indicators have reached the technical level of similar foreign products, due to the use of a unique single-channel impeller, Two sets of special materials carbide mechanical seal, with no clogging; durable, accurate line, easy to use and maintain, high efficiency, energy-saving significant, is China's pump replacement of the latest products, welcomed by users. Second, the main purpose and model description This series of non-clogging sewage pump, suitable for conveying industrial wastewater and municipal sewage, its biggest advantage is that it has a strong self-priming capacity, suction pipe without bottling valve, can transport solids containing particles It is widely used in mining, construction sites, hospitals, hotels, sewage treatment and other occasions in addition to the application of sewage, but also for the sewage pump, pulp pump, filter flush condensate circulating pump, irrigation pump and so on. . Suitable for medium temperature 0-250 degrees. Third, the pump model description ZW (F) 100-80-8 Z - self-priming; F - flow components 1Cr18Ni9Ti; 80 - the provisions of flow m3 / h; W - sewage dirt; (M); 4, Structure Introduction This series of non-clogging sewage pump, to meet the different requirements of users supporting the material is cast iron, stainless steel, and can be equipped with explosion-proof motor, the structure of the motor, Pump composition. 1, the motor adopts Y series asynchronous motor, B class insulation. 2, part of the pump, the pump is located at the other end of the motor, the pump impeller single blade, large passage, sewage and strong, easy to plug, pumping containing fiber material and suspended solids impurities in the dirt, using double mechanical seal to ensure that the transmission medium No leaks.
