There are two ways to do this. The first is to regularly inspect the pump frequently for leaks, vibrations or abnormal noises and check for wear on components by dismantling the pump. Another option which is much less labour intensive, is to have pump monitoring installed. We monitor your unit 24/7 for abnormalities, and our monitoring equipment is accurate enough to determine pump failure between 3 and 12 months in advance of failure avoiding downtime, frequent unnecessary inspection and unscheduled stoppage. Maintenance engineers are free to work on projects proactively, with significant cost savings made not only through avoidance of downtime, but avoidance of expedited deliveries such as airfreight charges, expedited production charges and time spent troubleshooting.
