The ZJ Series Slurry Pumps are horizontal, axial-suction,single-state,single-suction and centrifugal slurry pumps. The series pumps, through combination of advantages of similar products both at home and abroad and innovation in the aspects of hydraulic design,structural design and materials of flow passage companents, own the features of high efficiency, energy conservation, small vibration, low noise,reliable operation, long service life and easy maintenance. The comprehensive performance of pump takes the leading role in china, and most of pump’s efficiency indexes reach international advanced level. It is applied to the transport of abrasive paste with solid particle in electric power, metallurgical,coal,building materials and other industries, such as hydraulic ash removal of guel electric plant, pulp transport of metallurgical dressing plant,coal paste and dense media transport of coal washery. The allowed maxium paste weight density of solid-liquid mixture(Cw) is 45% of ash paste and coal paste, and 60%of pulp and dense media. The type include 450ZJ、350ZJ、300ZJ、250ZJ、200ZJ、150ZJ、100ZJ、80ZJ、65ZJ、50ZJ、40ZJ, which are appropriate for operation under the working conditions of flow rate of 4.5m³/h~6000 m³/h and pumping head of 6m~134m. There are totally 70 types of pumps.
