Pump station design calculations, without the spreadsheet
System head curves, pump selection, and NPSH checks — calculated on the server with a validated engine, organized by project, and shared across your whole team. No more hunting for the one macro-enabled workbook that still works.
Pump Calculator
Build system head curves from your pipe and fitting line items, overlay manufacturer pump curves with affinity-law scaling for speed, impeller trim, and parallel pumps, and see the chart redraw the moment you change a value.
NPSH Calculator
Check suction-side pressure margin against cavitation risk — site elevation, water temperature, and suction piping losses feed straight into an NPSH available vs. required curve.
More tools on the way
Pump House Tools is built to grow — every new calculation tool shows up right inside your existing projects, alongside the ones you already use.
Organized by project
Projects belong to your company, not to one person's laptop. Customer Admins manage who has access; everyone sees exactly the projects they're assigned to.
Calculates as you type
Edit a diameter, a C-value, a curve point — the chart and results update on blur, no "recalculate" button, no waiting for a macro to finish.
Built for the field and the office
Light and dark themes, a layout that works on a tablet, and print-ready output for submittals and design memos.
