The PN type slurry pump features a simple structure, reliable operation, and long service life. It is suitable for use in mining, power plants, construction, and environmental protection units for transporting ore sand and slurry. The maximum concentration of the transported slurry, by volume and weight, is 50-60%. It can also be used in industries such as building materials, papermaking, textiles, food, and feed for transporting various slurries. Note: The PN type pump must be supplied with a certain amount of shaft seal water, typically 1-3% of the working flow rate, and the water pressure should generally be greater than the working pressure by 1 kg/cm².
