A facility just replaced several 1,000 HP slurry pumps with a massive 4,000 HP slurry pump at a pumping station. As part of this project, Ludeca supplied a WEARSCANNER® particle counter that is installed on the oil return line just before the filter. This system reports partials per minute for different particle ranges and relays this data via Modbus to the process control computer. During the initial start-up, the particle counter showed particles passing through the counter with the worst range reporting 6 parts per minute in the 100 to 125-micron range. The startup oil was changed and the filter replaced.  As a result, the particle count has now dropped to zero in all of the ranges.
