About PumpToolkit

Practical online tools for preliminary pump engineering calculations.

What PumpToolkit is

PumpToolkit is a practical engineering toolbox for pump engineers, project engineers, technical sales engineers and students working with centrifugal pumps and piping systems.

The goal is to provide quick preliminary calculations, clear formulas and useful engineering context without replacing detailed vendor selection software or project-specific engineering review.

What we publish

  • pump and piping calculators,
  • short engineering notes,
  • formula explanations,
  • practical examples,
  • guides for NPSH, pump power, specific speed and system checks.

Disclaimer

All calculations are provided as preliminary engineering aids only. Critical applications must always be verified against project specifications, applicable standards, manufacturer data and qualified engineering judgement.
