Reduced maintenance and water consumption at Iron Ore Mine ...

An iron ore mine in Australia was experiencing unacceptably high maintenance costs on its Warman ® Thickener Underflow pumps. The pumps were sealed with Gland Packing that was flushed with 48litres per minute. The pump packing required almost constant maintenance, one of the pumps required repacking 11 times over a 34 day period.
