Fire pump types and where each applies, the NFPA 20 performance curve (rated point, churn, 150% flow), sizing a pump from a hydraulic demand, electric vs. diesel drivers, controllers and the jockey pump, and pump room requirements.
A fire pump only exists because the available water supply can't deliver the pressure and flow a system's hydraulic calculation demands on its own. This module walks through the three centrifugal pump configurations engineers actually choose between — horizontal split-case, vertical turbine, and vertical in-line — and why the choice comes down almost entirely to where the water source sits relative to the pump, not preference. From there it works the NFPA 20 performance-curve checks (churn pressure, the 150% flow point) and a full worked pump-selection example from a hydraulic demand and a flow test, with real numbers at every step.
The second half covers the driver reliability question — why NFPA 20 doesn't let a designer default to electric drive, and what a diesel driver trades for its own self-contained power — plus the controller/jockey pump relationship and the pump room's temperature, separation, and access requirements every real installation has to satisfy.
