Slurry Suspension Transitions to Solid

A pump designed to move a highly concentrated slurry in a Pulp and Paper Mill was experiencing significant vibration events. The plant was forced to shut down the pump several times attempting to find the source of the vibration.

Battery powered vibration sensors were temporarily installed on the pump. Because the sensors use a powerful magnet to attach to the equipment it was fast and easy to move their position to isolate the root cause problem. In this case decantation of the slurry had caused solid pulp to separate and accumulate in the volute of the pump.

Following corrective action, the intermittent vibration disappeared. The customer was so happy with the results that they left the sensors in place and added a cellular gateway to monitor and prevent similar events in the future.
