PumpLine helps fire pump operators determine the pump discharge pressure (PDP) needed to deliver a target fire stream. Using established fire-service hydraulic calculations, PumpLine brings nozzle pressure, hose friction loss, elevation, appliance loss, water source, and line layout into one clear operational setpoint. Pump Setups are at the center of the app. Build a Pump Setup for a specific department, apparatus, discharge, hose layout, and nozzle. Save it for training, then recall it in Operator for an at-a-glance pressure reference. Key capabilities include: • Clear PDP, intake pressure, boost, and operating conditions • Quick adjustments for flow, hose, nozzle, elevation, and water source • Pump Setups organized by department and apparatus • Reference, Field Tested, and Needs Retest Setup status • Nozzle pressure, reaction force, exit velocity, and estimated reach • Single-line, split, siamese, and standpipe-style configurations • Compatible QR Setup exchange between PumpLine on iPhone and Android • Shareable Setup Images and Pump Setup library backup • Offline operation on iPhone and iPad PumpLine is an educational and operational reference. Confirm calculated values using department SOPs, apparatus gauges, equipment data, manufacturer guidance, and qualified operator judgment.
