PDP stands for what in fire pump operation?

• A. Pump Discharge Pressure
• B. Pressure Differential at the Pump
• C. Dynamic Pump Pressure
• D. Discharge Pressure Parameter

Answer: (A)

The pressure you monitor on the discharge side of the pump is what PDP refers to. In fire pump operation, PDP means the actual discharge pressure coming from the pump into the hose lay and nozzles. This value is what you use to ensure you’re delivering the required pressure to achieve the desired nozzle pressure while overcoming friction losses in hoses and any elevation changes. It’s the tangible readout you adjust the pump to achieve, by balancing throttle and engine speed, to maintain effective flow to the attack lines. It isn’t the pressure differential across the pump (that would be a different measurement), nor a generic dynamic value or a vague parameter. Therefore, the correct interpretation is Pump Discharge Pressure.
