I. Product Overview: ZW Self-priming non-clogging sewage pump is based on the Division ZX-type self-priming centrifugal pump and QW structure and properties of submersible sewage pumps, the advantages of similar foreign products reference, developed from the set of self-absorption and pump sewage to a new species. Either as a general self-priming pump that water without having to install a foot valve, without irrigation water, but can pump large solid particles having a diameter of 60% and fiber length outlet diameter of the impeller diameter of 1.5 times the dirt, sediment, abandoned mine impurities, excreta disposal and all sewage works and colloidal liquid, reduce labor intensity entirely human, and easy to install, minimal maintenance, performance reached the international advanced level, with broad applications and development prospects. Second, product characteristics: 1, sewage capacity: blockades special impeller design to ensure efficient and non-clog pump. 2, energy efficient: using hydraulic model, self-priming high-efficiency than the average of 3 to 5 percent. 3, self-priming performance: self-absorption than the height of one meter high general self-priming and self-absorption time is shorter. Third, the product uses: ZW Self-priming non-clogging sewage pumps for the chemical, petroleum, pharmaceutical, mining, paper, fiber, pulp, textile, food, power plants and municipal sewage works, public facilities, sewage, farming and other industries Ponds . Fourth, the technical parameters: Flow: 5-800m3 / h; Head: 12-60m; motor power: 2.2-55KW; speed: 1450-2900r / min; diameter: φ25-φ300; medium temperature: ≤100 ℃; self-priming height : 4.5-6.0m. V.
