and unplanned production downtime. However, a growing number of customers are adopting a TCO approach, leveraging Weir’s technical studies to identify more effective ways to reduce long-term operational expenses. “Many of our larger customers ask us to carry out formal assessments to help reduce the operating costs of specific equipment,” West explains. “In many cases, we collaborate directly with their dedicated reliability engineers. For smaller companies without such specialised roles, we step in with our expertise and insights to help lower running costs while enhancing both production efficiency and safety.” One such example was a tailings recovery plant in South Africa, where profitability was closely tied to controlling operational costs. The plant’s owners sought to reduce their total equipment ownership costs by cutting downtime and energy usage. After discovering that replicator parts on the wet end of their Envirotech® Alpha D-Frame pumps were lasting only two months, Weir recommended upgrading to its Wear Resistance Technology - WRT® impeller and throatbush for improved durability and performance. “These WRT parts are a great example of how advanced materials and enhanced hydraulic design can significantly improve efficiency, net positive suction head (NPSH) performance and wear life,” he says. “In this particular application, the OEM parts lasted twice as long, reduced power consumption by drawing lower amperage and delivered a higher head.” West notes that Weir also provided a service technician to support the installation of the upgraded parts and deliver training on general maintenance. This collaboration with the OEM not only ensured proper implementation but also helped enhance the plant’s skill base, contributing to improved equipment longevity and reliability. “The efficiency benefits of OEM parts are even more significant in remote operations powered by diesel generators, where grid energy is unavailable,” he notes. “In such cases, the high cost of energy can be substantially lowered by ensuring all equipment operates at peak efficiency.” Power consumption directly correlates with carbon emissions, which mining companies are increasingly required to reduce to meet their corporate sustainability targets, further underscoring the environmental value of using high- quality OEM parts. l
Original Weir parts boost the equipment’s production capabilities and support smooth operation of the plant.

The original parts also boost the equipment’s production capabilities, supporting smooth operation and maximising uptime.
In many cases, replacing an old generation part with a newly designed one actually enhances the overall performance and efficiency of the equipment.
The efficiency benefits of OEM parts are even more significant in remote operations powered by diesel generators, where grid energy is unavailable.
OEM parts incorporate all of Weir’s latest technological advancements, enhancing efficiency, optimising hydraulics and extending wear life.
our latest technological advancements; enhancing efficiency, optimising hydraulics and extending wear life,” he says. Precisely engineered to fit perfectly, the original parts also boost the equipment’s production capabilities, supporting smooth operation and maximising uptime. “The extended service intervals our parts provide contribute directly to the overall efficiency and profitability of our customers’ operations,” he explains. “They also help minimise the risk of unplanned downtime due to premature component failure.” He points out that users who source non-genuine replacement parts often overlook the significant costs associated with emergency repairs
