<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n<\/figure>\n\n\n\n\u201cOur global studies show that the capital cost of a pump and spare parts represents less than about 10% of its total cost of ownership (TCO) over its lifespan,\u201d says West. \u201cSince energy accounts for nearly 60% of this lifetime cost, opting for a cheaper but less efficient pump can quickly lead to significantly higher operating expenses.\u201d<\/p>\n\n\n\n
Weir not only guarantees that its spare parts meet world class design and manufacturing standards, but also fine-tunes their performance to help customers reduce energy consumption and operational costs. West says that this is done through correct equipment selection as well as on-site process fault finding. \u201cManufacturing standards in many non-OEM supplied pump parts are not adhered to, which also presents potential safety risks to the customer,\u201d he says. <\/p>\n\n\n\n
\u201cThe OEM part incorporates all of our latest technological advancements, enhancing efficiency, optimising hydraulics and extending wear life,\u201d he says.<\/p>\n\n\n\n
Precisely engineered to fit perfectly, the original parts also boost the equipment\u2019s production capabilities, supporting smooth operation and maximising uptime.<\/p>\n\n\n\n
\u201cThe extended service intervals our parts provide contribute directly to the overall efficiency and profitability of our customers\u2019 operations,\u201d he explains. \u201cThey also help minimise the risk of unplanned downtime due to premature component failure.\u201d<\/p>\n\n\n\n
He points out that users who source non-genuine replacement parts often overlook the significant costs associated with emergency repairs and unplanned production downtime. However, a growing number of customers are adopting a TCO approach, leveraging Weir\u2019s technical studies to identify more effective ways to reduce long-term operational expenses.<\/p>\n\n\n\n \u201cMany of our larger customers ask us to carry out formal assessments to help reduce the operating costs of specific equipment,\u201d West explains. \u201cIn 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.\u201d<\/p>\n\n\n\n One such example was a tailings recovery plant in South Africa, where profitability was closely tied to controlling operational costs. The plant\u2019s 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\u00ae Alpha D-Frame pumps were lasting only two months, Weir recommended upgrading to its Wear Resistance Technology – WRT\u00ae impeller and throatbush for improved durability and performance.<\/p>\n\n\n\n \u201cThese 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,\u201d he says. \u201cIn this particular application, the OEM parts lasted twice as long, reduced power consumption by drawing lower amperage and delivered a higher head.\u201d<\/p>\n\n\n\n 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\u2019s skill base, contributing to improved equipment longevity and reliability.<\/p>\n\n\n\n \u201cThe efficiency benefits of OEM parts are even more significant in remote operations powered by diesel generators, where grid energy is unavailable,\u201d he notes. \u201cIn such cases, the high cost of energy can be substantially lowered by ensuring all equipment operates at peak efficiency.\u201d<\/p>\n\n\n\n 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.<\/p>\n","protected":false},"excerpt":{"rendered":" Using genuine parts enables Weir customers to achieve higher equipment efficiency and extended lifespan, thanks to ongoing enhancements integrated into every component. \u201cWith our continuous investment in research and development, along with our commitment to quality design and manufacturing, we ensure that customers benefit from improved energy efficiency and longer-lasting spare parts,\u201d says John West, … Continue reading WEIR PARTS ENGINEERED FOR EFFICIENCY<\/span> <\/figure>\n<\/figure>\n\n\n\n
