During the 1960’s the rapid growth of the business continued with manufacturing and sales outlets established around the world. The Warman® Series ‘A’ pump was accepted and became world leader in its field. Further work on the Warman AH® pump resulted in the development of interchangeable metal and rubber wearing components.

Always Improving

The Warman AH® pump range was extended with the addition of the AHP high-pressure pump in 1974. At the time, this was the largest rubber-lined high-pressure slurry pump in the world, and is still in service today in many tailings pipelines across the globe.

Innovations continued throughout the decades, with pumps designed for a number of tough applications including Flue Gas Desulphurisation. In 1994, the Warman® GSL pump was developed to handle high flows and corrosive slurry. It took the market by storm due to its superior performance and long life and became the global standard.

“I think one of the key reasons for the growth of the Warman pump was that it was reliable, people came to trust it because it had been around for so long. It was this trust that enabled them to focus on other things in the plant and not have to worry about the pump stopping their business,” states Marcus Lane.

Always Innovating

The Weir Group Plc acquired the Warman® pump in 1999, and a whole new chapter began. As part of the Weir Minerals division, a number of technological advancements were achieved for the Warman® pump range. 2002 saw the development of a revolutionary new impeller and inlet design for pumping mineral froths and high-density viscous slurries, and in 2009, Weir Minerals developed the Warman WBH® pump with axial and rotationally adjustable throatbush to even out wear. Due to its innovative design, this pump soon became the new slurry pump standard.
