What should the engine RPMs be during drafting operations?

During drafting operations, maintaining the engine RPMs within the range of 1000-1200 is important for several reasons. Operating the pump at this RPM allows the pump to achieve optimal performance while ensuring adequate pressure and flow. This range typically ensures that the pump can effectively generate the necessary vacuum to pull water from the source, which is crucial during drafting.

Additionally, running the engine at this RPM helps prevent cavitation, a condition that can occur when there is insufficient pressure in the pump, leading to damage and reduced efficiency. By keeping the RPMs at this level, firefighters can ensure that the pump operates smoothly and effectively throughout the drafting process.

While other RPM ranges could be considered for different situations, 1000-1200 RPM is specifically optimized for drafting scenarios, providing a balance between engine performance and pump efficiency.
