Engineering Tips

Fill in the parameters, then press Calculate to compute the active tab.

  • Shaft power: leave α blank to auto-apply the API 610 bracket.
  • Seal PV: a lower PV means longer seal-face life.
  • Ns: low → radial impeller, high → axial.
  • S/Sa: keep S ≥ Sa to stay clear of cavitation.
