GROVETOWN, Georgia – An LSA model slurry pump installed at the Noranda alumina plant in Gramercy, LA, has operated continuously with only routine maintenance for 52 years, according to the proud manufacturer, GIW Industries.
Installed at the plant start-up in 1959, the LSA pump operates on the press floor turn back area, handling bauxite mud slurry at a specific gravity of 1.25 and temperature of 51°C. The slurry is fed to the pump from a tank that receives excess mud, caustic liquor and dilution water from the filter press that dewaters mud for disposal. The pump recirculates excess material to a mud settler tank located approximately 60 metres away.
More than 150 GIW pumps in the Noranda plant handle the hot, abrasive slurries as they are moved from the milling and slurry mix areas to the digesters. Then the pumps move the slurries through the processes of mud separation and filtering, precipitation and calcinations to create the finished dry alumina product.
David S. Pratt, president of GIW partner Hunter Equipment Co., says, “GIW pumps have proven to be a vital part of this plant’s success as one of the most efficient alumina plants in the industry. The high chrome alloys used in the GIW pump line provide excellent abrasion resistance and long life cycles in severe duties and provide the plant with reliable performance and lower maintenance costs than other brands of pumps.”
