Pump selection analysis
Calculate the system curve, then read the operating point.
Build it from static head, friction losses, and fittings. Plot or import a pump curve, check NPSH, and export a professional PDF report.
Then C$15/month. A card is required. Open the calculator
How it works
01
Calculate the system curve
Static head, friction losses, and fittings. Or start from a duty point you already know.
02
Plot or import the pump curve
Trace a published sheet by hand, or import a PDF and map the speeds or diameters.
03
Read the operating point and the report
Duty and NPSH stay on screen. Pro exports the professional PDF that goes with the quote.
Includes a searchable library of published Gorman-Rupp performance curves.
What Pro adds
The calculation stays free. These three are on the C$15/month plan.
- Pro
Automatic Curve Mapping
Reads printed speeds or diameters on supported Gorman-Rupp curve PDFs after you confirm the axes.
- Pro
PDF report exports
A professional PDF: duty, friction on suction and discharge, the NPSH check, the methods used, a sketch, and the curve.
- Pro
Custom Presets
The lift station, fuel offload, or HDPE run you size every week, saved on your account.
Questions
- How does the free trial work?
- Pro is free for 30 days. A card is required to start, and you are billed after that unless you cancel. One trial per account.
- What stays free?
- The study on screen: system curve, operating point, NPSH check, catalog search, and hand plotting.
- Are reports sealed calculations?
- No. Reports are for engineering review. Confirm them against the manufacturer’s published data.
