We have carried out a complete overhaul of a Byron Jackson centrifugal pump for an oil refinery. The pump has been completely cleaned, inspected and disassembled on arrival. The pump was then fully measured and all dimensions and tolerances were reported. To get this pump back in top condition, we carried out a complete overhaul, including customizing the wear rings on the impeller, balancing the shaft and clearing various fits. The pump was returned to the customer within a few days.
