Low flow + high RPM heats the pump. Cavitation damages pump and kills pressure.

Tip: For a stable attack line, open the discharge valve, bring RPM up, then fine-tune to hit nozzle pressure.
If drafting, use primer to build/maintain prime.
Source affects intake pressure and cavitation margin.
Primer helps when drafting; without prime you get air and pressure collapses.
About Real Pumpscontext
Real fire truck pumps are typically engine-driven centrifugal pumps delivering roughly 1,000–2,000+ GPM.
Operators manage intake, discharge valves, primer, and engine RPM to hit target pressures while avoiding cavitation and overheating.
