John Brooks Company Limited offers no shortage of customer success stories to back up its reputation. The supplier saved a major steel and mining company $130,000 a year with a pump solution that increased abrasion resistance in its rolling mill’s scale pits. With the Gorman-Rupp Super T Series of self-priming centrifugal pumps (specifically, the Model T10A60S-B), the mill achieved a 300 per cent boost in up-time and equipment lifespan.
A two-component coating system
The rolling mill made special-grade and merchant bars to reinforce steel bars and other semi-finished steel items. The customer sent all water back into a sump to minimize water consumption and reuse as much process water as possible in production. Screens separated the sump into different settling pits to stop solids from getting pumped back into the system. But the existing pumps in hardened metals kept failing, which resulted in low productivity, and it cost up to $35,000 to replace them.
The steel manufacturer needed reliable, durable pumps that could handle abrasive liquids. An application expert with John Brooks Company recommended the Model T10A60S-B as a replacement. This unit is constructed with a grey iron casing, and the John Brooks Company team applied a two-component coating system to all wet components to improve erosion-corrosion resistance. The coating, a ceramic-filled epoxy, ensured longer durability on wearing parts to withstand high solid-loading slurry.
Among the other benefits of the Model T10A60S-B: more efficiency for intermittent pumping, due to the self-priming; lower maintenance downtime with easy service; replaceable wear components, so the pump does not require regular overhaul; and component coating that can be re-applied.
The mill rented this pump for more than a year without any failure. This alone made the model a far better investment from the previous pumps, which lasted only three-to-eight months. The previous pumps cost from $28,000 to $35,000 each; the Model T10A60S-B pumps cost $35,000 all-in, but with service costs of only about $10,000 a year – a 92 per cent decrease in replacement expenses.
