Weir Minerals is celebrating 80 years of the Warman® slurry pump. Invented by Charles Warman in Kalgoorlie, Western Australia in 1938, the Warman slurry pump used replaceable liners and a replaceable impeller, something that had never been done before. The Weir Group acquired the Warman pump in 1999.
As part of the Weir Minerals division, there have been a number of technological advancements for the Warman pump range including a new impeller and inlet design for pumping mineral froths and high-density viscous slurries in 2002, and the Warman WBH pump with axial and rotationally adjustable throatbush to even out wear in 2009.
