INDUSTRY Warman® pumps reduce downtime and improve performance at ArcelorMittal Kryvyi Rih, CUSTOMER saving the customer US $98,000 a year ArcelorMittal Background extending pump wear life, significantly LOCATION reducing maintenance and enhancing ArcelorMittal, one of the world’s leading safety to operational personnel. Kryvyi Rih, Ukraine and mining companies, has been operating the Kryvyi Rih iron ore plant ArcelorMittal progressively implemented a EQUIPMENT in the Ukraine since 2005. The company pump replacement project under the Warman® AHP 20/18 operates in 60 countries, producing guidance of the Weir Minerals’ process high-pressure slurry pump and products for use in the automotive, engineering team which included, six Warman® GHPP 28/24 and household appliance Warman® AHP 20/18 high-pressure slurry high-pressure gravel pump industries. pumps, and nine Warman® GHPP 28/24 high-pressure gravel pumps. Weir Minerals have supported the Kryvyi Rih site for twelve years, and were The Results instrumental in supporting the Increased pressure delivered productivity improvement of the tailings pumps’ increases in excess of 60%, by 2,000m3 to performance. 5,000m3. Maintenance intervals reduced The Challenge from three times per year to a single change-out annually, thus saving some 90 The installed pumps were notorious for hours a year on maintaining the Warman® deficient performance, delivering low AHP 20/18 pumps, and 120 hours per year pressure and capacity. The average wear on the Warman® GHPP 28/24 pumps. life was between 3,000 – 4,000 hours: requiring frequent mechanical breakdown ArcelorMittal estimates this to be a saving repairs and complete pump disassembly of approximately US $98,000 per year. three times annually. Given that only partial dismantling was required to undertake maintenance, the The Solution repair process was simplified, thus also Weir Minerals’ process engineering team reducing the safety risks to maintenance proposed a solution which would increase personnel. pressure, flow-rate and productivity while Vladimir Teslyuk, Director of the Mining Department at ArcelorMittal Kryvyi Rih said: ‘The Weir service team fully understood the problem and provided a simple, yet technically good solution, which improved the efficiency of our operations while reducing maintenance costs. Our time spent on repairs has greatly reduced, bringing savings of around US $98,000, and a total reduction of 215 man-hours previously dedicated to pump repairs per year.’
