Hydraulic pump sizing for engineers & field technicians
We're happy to help with questions, bug reports, or feature requests. We typically respond within 2–3 business days.
Or write to el.pipero.app@gmail.com. When reporting a problem, please include your device model, iOS version, and a short description of what happened.
What is Pump Mate?
A professional, offline hydraulic calculator for sizing and analyzing centrifugal pumps — pump power, TDH, NPSH, pipe and fitting losses, motor selection, and pump curves. It works in both metric (SI) and imperial units.
Do I need an account or login?
No. Pump Mate requires no account — every feature opens directly, and your calculations stay on your device.
What's the difference between Quick Mode and Advanced Mode?
Quick Mode gives a fast power and motor-size estimate from flow, head, and fluid density. Advanced Mode runs a full hydraulic analysis — liquid properties, operating conditions, piping and fittings, pump configuration, and efficiencies — for TDH, NPSHa, and detailed results.
What does Pump Mate Pro include?
Pump Mate Pro is a one-time, lifetime purchase that unlocks the full professional pump-curve library (60+ curves from manufacturers such as Grundfos, KSB, and Flowserve, with H–Q, efficiency, power and NPSHr data) and slurry calculations. The core calculators are free to use.
How do I restore a purchase on a new device?
Open Pump Curves, tap any locked curve to open the upgrade screen, then tap Restore purchase. As long as you're signed in with the same Apple ID used for the original purchase, Pro will be restored at no charge.
I was charged but Pro didn't unlock.
First try Restore purchase on the upgrade screen. If it still doesn't unlock, email us at el.pipero.app@gmail.com with your purchase date and we'll sort it out. Refund requests for App Store purchases are handled by Apple at reportaproblem.apple.com.
Does Pump Mate work offline?
Yes. All calculations run entirely on your device and need no internet connection.
Can I switch between metric and imperial units?
Yes — open Settings to choose your unit system and language (English, Spanish, French, or Portuguese).
How are your results calculated?
Pump Mate uses standard hydraulic engineering methods (e.g. Darcy–Weisbach friction losses, standard motor sizing). Results are engineering estimates and should be verified by a qualified engineer before use in design or procurement.
