Match the potential cause of pump shutdown with the potential troubleshooting solution:
I. Power failure
II. Flow, pressure, or vibration
III. Overspeed trip
IV. Motor trip-out
a. Check turbine overspeed trip for proper operation; check suction for proper flow; check discharge lines for large failure.
b. Determine cause (for example, breaker, fuse, or loss of commercial power). Repair and restore power as appropriate.
c. Pump is using too much horsepower, flow rate is too high, or mechanical problems exist. Correct problem to return pump to operation.
d. Determine cause (for example, leak, valve closed, or instrumentation elsewhere in the process). Correct problem to return pump to operation.
