Impeller Tip Speed Calculator
Peripheral speed of an impeller — wear, NPSH and emulsification screening.
Slurry-pump wear rises with tip speed to the ~2.5 power — half the tip speed, ~6× the liner life. Shear-sensitive products (latex, polymers) also live by this number.
Formula
Impeller Tip Speed Calculator is a free impeller tip speed for pump engineers, plumbers and plant designers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Impeller Tip Speed Calculator
Peripheral speed of an impeller — wear, NPSH and emulsification screening. The calculation implements u = π·D·N/60 (Warman Slurry Pumping Handbook). Slurry-pump wear rises with tip speed to the ~2.5 power — half the tip speed, ~6× the liner life. Shear-sensitive products (latex, polymers) also live by this number.

Frequently asked questions
What formula does the Impeller Tip Speed Calculator use?+
It computes u = π·D·N/60, per Warman Slurry Pumping Handbook. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Slurry-pump wear rises with tip speed to the ~2.5 power — half the tip speed, ~6× the liner life. Shear-sensitive products (latex, polymers) also live by this number.
Can I use this for pump selection?+
Use it to establish the duty (flow, head, NPSH, power) and then pick a pump whose curve passes through that point near best efficiency. The tool gives you the engineering numbers a supplier will ask for.
Is the Impeller Tip Speed Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
