About

Pool Pump Pro

Read full description

Pool Pump Pro helps pool professionals evaluate existing pumps, select replacement pumps, and compare pump options using hydraulic inputs and verified pump curves. Use the schematic workflow to enter pool volume, pipe runs, fittings, valves, equipment pressure, voltage, and optional field gauge readings. The app calculates required flow, TDH, suction and return losses, NPSHa, validation confidence, and pump curve performance. Key features: - Existing pump evaluation for installed equipment - Replacement pump selection using curve-ready pump data - Pump-to-pump comparison tables and curve charts - Simple and professional pool-parameter modes - Field gauge shortcut for P1/P2 vacuum and pressure readings - Custom pump library with reviewed curve support - Project save/load and professional report export Pool Pump Pro is built for pool service companies, builders, engineers, and technicians who need repeatable pump sizing and diagnostic documentation in the field.
