The PN type mud pump features a simple structure, reliable operation, and long service life. It is suitable for use in mining, power plants, urban construction, environmental protection, and other units for transporting ore sand and mud. The maximum concentration of the transported slurry, by 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.
