Processing systems consuming significant volumes of water are widely applied at concentrators in the mining and mining-chemical industries, where pumping equipment is used for pumping slurries. The most popular are centrifugal slurry pumps, used for pumping medium and high abrasion materials in crushing process lines and downstream of primary and secondary grinding mills, as well as for the high-pressure transportation of concentrates and tailings of concentrating plants, etc. These pumping applications involve high slurry pump component wear, requiring frequent repairs or replacements. The operation of such pumps is also associated with high power consumption. When selecting slurry pumps, domestic enterprises prefer those options that minimize the purchasing costs of the pumping equipment. This paper provides an overview and analysis of the main trends in the upgrades of slurry pumps, including the design features of the most advanced single-stage centrifugal pumps, the use of information technology and studies on power consumption by pumping equipment.
