Pump calculations in seconds.
PumpOps is a fast, dead-simple engine pressure calculator built for fire apparatus engineers and operator candidates. Pick your nozzle, hose, and layout - the pump discharge pressure updates instantly, with the full equation shown so you always know where the number came from.
BUILT FOR SPEED - One screen. Instant PSI. - Live equation breakdown: NP + FL + Appliances + Elevation - Friction loss shown per 100' for every hose selection
COVERS THE FULL LAYOUT - Fog and smooth bore handline nozzles - Master streams, monitors, deck guns, and ladderpipes - Up to three hose lays, including two- and three-line big water - Appliances: wye, siamese, monitor, ladderpipe, standpipe - Elevation by floor or by feet, above and below grade - Helicopter fill lays included
REFERENCE AND TRAINING TOOLS - Interactive formula calculators: friction loss, nozzle discharge, standpipe ops, relay pumping, and more - Hose coefficient calculator with a live flow scale - Nozzle GPM and pressure quick-reference tables - Over-pressure warning when a layout exceeds safe pumping limits
MAKE IT YOURS - Save and name your favorite hose lays - Drag to reorder presets so your most-used lays are on top - Color, dark, and light themes with adjustable display size
TRAIN WITH CONFIDENCE Every calculation follows standard fireground hydraulics used in apparatus operator training, verified against department-style pump charts.
