ZW Series self priming and non-clogging pump is a new structure product which is developed on basic of domestic and foreign advanced technology.. This kind pump has feature of simple structure.,good self priming performance and high sewage ability, high efficiency and energy saving, convenient usage and easy maintenance etc . And it belongs to the first designing in the country at sewage pump series. All technology and performance data are on top of the nation. Reaching the international advanced level. So it has the wide application market and developing future.
This kind pump combines self priming and non-clogging, adopting axial circumfluence outer-mix type. And through the particular design of case and impeller channel. It not only needn’t to be fixed with foot valve and poured in water like normal self priming, but also can suction and discharge liquid containing big grain and long fibre substance. So it is widely used in municipal sewage project, river and pond breeding, light industry, papermaking, weaving, foodstuff, chemical industry, power industry, fibrin, slurry and mixed suspend ,chemical medium and so on
1. Surrounding temperature ≤ 50℃, medium temperature ≤ 200℃.
2. Medium consistency should not exceed 1240 kg/m3
3. Self priming height should not exceed the stated number of 4.5-5.5 meters, and the suction pipe should not be over 10 meter long.
4. It can pass the suspended grain whose diameter is 60 percent of punp caliber, and the fiber which is 5 times longer of pump caliber.
5. PH range of liquid: 6-9 (for cast iron pump), 2-13(for stainless steel pump).
