SPECIALIST EQUIPMENT
The strength of the Warman slurry pumps lies in their advanced hydraulic designs and high-performing wear
Manufacturing methods T e manufacturing methods and processes used by OEMs have been developed over many years using expert engineering solutions. OEMs know their products inside out; they know what works and continuously make advancements to improve their technology. “We have access to plant, operational and performance data to continually track and analyse trends. We spend the time to understand our customers’ needs, gain feedback and make developments based upon that feedback to make them more productive,” Otten continues. Production facilities that manufacture genuine spare parts using the latest materials are highly sophisticated and usually employ very expensive machinery. It is unlikely that
replicators would have the equipment or the knowledge to satisfactorily machine these specialist materials. Taking into account the necessity to match, optimum tolerance, the correct material properties, method of manufacture and the high cost of good quality tooling, the likelihood of achieving anything like the overall performance of the OEM part is absolutely minute.
Optimisation A replicator may recreate the spare part but it often fails to optimise it. It is not always as simple as just replacing the worn part; fi rst the operator must understand the nature of the problem. “We often take samples of the worn parts and send them to our experts in the materials laboratory to
analyse. Proper examination of the worn parts’ physical characteristics, by the people who know the design and manufacturing process of the slurry pump, can reveal the root cause of the wearing, and allows us to engineer the correct solutions specifi c to the application,” says Otten. T ere are many implications
with replicating genuine spare parts, presenting an array of consequences to mine sites across the globe. Operators considering a non-OEM
spare part for their slurry pump should think through the risk to maintenance costs, down-time, the eff ect on slurry system performance and energy costs, before making their fi nal decision.
