⚙️ NFPA 20 Jockey Pumps (1% System Flow Rate GPM, Cut-In/Cut-Out Differential PSI)

Fire Jockey Pump Sizing Calculator

Size pressure maintenance (Jockey / make-up) regenerative turbine pumps for wet fire sprinkler systems under NFPA 20: calculate flow rate (sizing pump for 1% of main fire pump flow or 1 to 5 GPM at higher churn pressure to recover normal underground packing leakage), set pressure switch cut-in/cut-out thresholds, and fire sprinkler maintenance margins.
