What should both Driver Engineers monitor during pumping operations?

Monitoring RPM limits and pump intake residual pressures during pumping operations is vital for several reasons related to safety and operational efficiency. The RPM (revolutions per minute) limits ensure that the pump and engine are operating within their designed parameters, preventing mechanical failure or damage. If the pump operates outside these limits, it may lead to overheating or excessive wear.

Additionally, keeping an eye on pump intake residual pressures is essential for maintaining adequate water supply to the pump. Insufficient intake pressure can lead to cavitation, which can significantly impair pump performance and potentially cause damage. By monitoring these parameters, Driver Engineers can ensure that the pumping operation stays within safe operational thresholds, thus optimizing performance and extending the longevity of the equipment.

The other options, while important in their own right, do not focus directly on the most critical parameters that ensure safe and effective pumping operations.
