The core of Sepro’s industrial mixing and pumping knowledge comes from years of troubleshooting and problem-solving. Sepro personnel have travelled the world identifying and solving some of the world’s most complicated mixing problems. Whether it’s insufficient suspension, gas flooding, impeller blade or shaft failures – we’ve solved process and mechanical problems from all types of mixing applications.
Mechanical problems are often rooted in process conditions. In addition to having direct process knowledge in most mixing and pumping applications, Sepro Mixing and Pumping draws on the expertise of the larger Sepro group of companies to develop holistic process solutions.
Approach with a purpose
In 1972, Warren founded a mixing and pumping business that soon became a leader in its field in South Africa. For 28 years, Warren and his collaborators introduced many agitation system innovations surrounding metallurgical plants, including draft tube circulators for gold and uranium leaching, axial gas dispersers for bacterial leaching and efficient solvent extraction systems. As part of a mutual development program Warren’s company, along with Billiton, Gold Fields and Biomin, worked to develop new bioleaching agitation systems of gold, copper and nickel. After selling his business in 2000, Warren became a consultant for high technology agitation systems, with a focus on large agitators for metallurgical plants – particularly bio-oxidation.
In 2010, Warren relocated to Canada where he formed CANAMIX Processing Systems, producing CANAMIX industrial agitators and peristaltic pumps. Six years later, CANAMIX and Sepro joined forces to bring Warren’s deep technical knowledge and experience to a much wider audience.
Francois van der Merwe
With a B.Eng, metallurgical engineering – focusing on hydrometallurgy – and 16 years of mineral processing experience, Francois brings a lot to the table within different areas of the industry.
Francois started as a metallurgist with Anglo American, covering duties such as metal accounting, process optimization, debottlenecking and new technology implementation. He moved into a process engineer position, working with equipment selection and sizing, hot and cold commissioning as well as client site support.
He eventually became general manager of Canamix Processing Systems under direct tutelage of Warren Dale. Francois’ wealth of process stream knowledge gave him the ability to approach the impact equipment or processes can have on Canamix products, with a more holistic point of view; offering clients the best the industry has to offer.
