PUMP ENGINEERING TOOLS
Pump Calculators for
Centrifugal & Process Pump Systems
Build a pump duty, check suction conditions, estimate pipe losses, calculate pump power and prepare engineering data for pump selection with browser-based tools designed for process-pump work. The calculators support practical SI and US-unit workflows while keeping the calculation basis visible for engineering review.
These tools support engineering screening and duty preparation; final equipment selection should be verified against the applicable pump curve, project specification and service conditions.

Find the Right Pump Calculator
Total Dynamic Head
Map static elevation, pressure and line losses into a traceable pump head requirement.
Pump System Hydraulic
Evaluate split discharge paths, Darcy friction and minor losses for a real system.
NPSH Available (NPSHa) Calculator
Check available suction head from absolute pressure, static lift and vapor pressure.
Pipe Friction & Minor Loss
Keep straight-pipe friction, Reynolds number and fitting losses separate and auditable.
Pump Power & Motor Sizing
Translate flow, head, density and efficiency into shaft power and a source-range motor size.
Affinity Laws / VFD
Compare flow, head and power as pump speed changes under the documented affinity laws.
Centrifugal / Chemical Pump Sizing
Prepare a duty package for engineering review without claiming an automatic pump model.
Liquid Ring Vacuum Pump Sizing
Calculate leakage, continuous exhaust and intermittent evacuation capacity from the source sheet.
Engineering workflow
From System Data to Pump Selection
Pipe losses contribute to total dynamic head, suction conditions determine NPSH available, and flow plus head define the hydraulic duty used for power and pump-curve review.
Source-validation method
Accuracy before selection.
Source files were audited locally, legacy workbooks were converted on copies, and every online result was checked against mapped regression values before release.
