Radford Series Self-Priming Pumps
The Radford Series self-priming sewage pump of this kind has features of simple structure, good self-priming performance, high sewage capability, high efficiency and energy saving, convenient usage and maintenance, etc., compared with similar domestic products. And it belongs to the first creation in the country’s sewage pump series. Moreover, all technology and performance indexes are on top of the nation, reaching an advanced international level. So it has a broad application market and a developing future. The demand for this product is continuing to grow and expand, and there is a potential for future development. The product is constantly being improved and updated, and new features are added continuously as new ways to improve the product and make it more user-friendly. They always seek user feedback to help them make the best possible product.
This kind of pump combines self-priming and non-clogging. It adopts an axial circumfluence outer-mix type. And through the particular design of the case and impeller channel, it not only needs to be fixed with a base valve and poured in water like normal self-priming, but also can suck and discharge liquid containing big grains and extended fibrin substance. So it is widely used in municipal sewage projects, river and pond breeding, the light industry, papermaking, weaving, foodstuff, chemical industry, power industry, fibrin, slurry, mixed suspension, etc., and chemical medium.
