Permanently installed MBVI system units were installed into the motor control cabinets of six pumps at a freshwater pumping station, including two borehole pumps – a focal area for the customer. After about one year monitoring these two borehole pumps, the system detected a variety of problems. After a further four months, we advised that one of the pumps should be replaced due to an impeller related problem and predicted the time to carry out maintenance work. To evaluate the accuracy of the system the pump was left to run, adopting the ‘run to failure’ strategy. Within a couple of days of the predicted date, the pump failed. The condition monitoring of borehole pumps is especially challenging due to their inaccessible location underground and the wide range of potential failure modes that can occur – many of which would remain undetected by other monitoring techniques. As the MBVI solution is installed in the motor starter panel and monitors both the electrical and mechanical parameters of the pump it is proven to be ideal for inaccessible applications.
