<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n<\/figure>\n\n\n\n\u201cOur aim was to enhance our current models to deliver superior wear life and energy efficiency,\u201d he says. \u201cThe WRT component combination does this by allowing upgrades that integrate seamlessly into existing infrastructure without extra capital investment.\u201d<\/p>\n\n\n\n
Introduced to the African market in 2010, WRT\u00ae components deliver an energy saving of 3 to 5% to WARMAN\u00ae AH\u00ae pump owners and have extended the lifespan of these pumps by from 30% to 50%. This has meant direct on-site cost savings and significantly reduced energy consumption from the large number of these pumps in operation worldwide.<\/p>\n\n\n\n
At the heart of the WRT\u00ae component breakthrough is improved hydraulic efficiency, achieved through advances such as the optimised design of the impeller and throatbush. For instance, the WRT\u00ae impeller features specially developed vanes that guide fluid more efficiently, reducing turbulence and minimising energy loss. <\/p>\n\n\n\n
\u201cThe design of the WRT impeller improves flow characteristics, compared to older designs with steeper vane angles,\u201d he explains. <\/p>\n\n\n\n In another innovation, the new design of the impeller guides fluid more efficiently to mitigate against the creation of eddies. These eddies are swirling circular currents of fluid which form within the pump volute due to turbulent flow, and lead to fluid moving against the main flow, wasting energy and increasing wear on internal components.<\/p>\n\n\n\n \u201cWe have also improved efficiency by minimising the surface area of the WRT impeller, by reducing the number of vanes from five to four,\u201d he says. \u201cThis creates more space for the material to flow while still delivering the same duty.\u201d<\/p>\n\n\n\n Critical to the impact that the WRT\u00ae component upgrade has had on energy efficiency in pumping operations is its enthusiastic uptake by the market. Koorts highlights that Weir\u2019s strategy was to make the transition for customers as easy and economical as possible. Being interchangeable with WARMAN\u00ae pumps\u2019 older technology, the WRT\u00ae components allow customers to switch over without extra capital expenditure \u2013 by changing to WRT\u00ae options when existing parts need to be replaced. <\/p>\n\n\n\n \u201cThis has already allowed most of our customer base to adopt the latest energy-efficient options,\u201d he says. \u201cIn Africa, for instance, all new WARMAN AH pumps sold contain WRT technology and a majority of our existing WARMAN AH pumps have already been converted.\u201d<\/p>\n\n\n\n With Africa being home to a large installed base of ENVIROTECH\u00ae pumps, the WRT\u00ae component technology has been extended to this popular range. Koorts notes that the company is committed to Africa and to the technologies currently in use. <\/p>\n\n\n\n \u201cFor the past two years, therefore, we have been supplying our ENVIROTECH pumps with WRT as standard,\u201d he says. \u201cToday, more than half of all our ENVIROTECH pump spares sales are WRT designs.\u201d<\/p>\n\n\n\n Underpinning these technical advancements is Weir\u2019s local investment in production capacity, which allows the company to cast and machine its pumps and components in South Africa.<\/p>\n","protected":false},"excerpt":{"rendered":" As part of Weir\u2019s mission to support its customers\u2019 sustainability efforts, Wear Reduction Technology (WRT\u00ae) upgrades have made both WARMAN\u00ae and ENVIROTECH\u00ae pumps more energy efficient and longer lasting.
