The YZB pump is a vertical fully cantilever submerged slurry pump. The hydraulic design of the pump fully considers the features of solid-liquid two-phase flow. The maximum temperature of the conveying medium is 70℃. The maximum concentration of the conveyed slurry is 50%-70% by weight. A small amount of large solid particles is allowed to pass, but the particles should not be larger than 80% of the minimum size of the flow section. It is widely used in metallurgy, mining, chemical industry, papermaking, thermal power plants and sewage treatment industries.
