Pump Temperature Rise Calculator
Liquid temperature rise across a running pump from power, flow and efficiency.
A fraction of a degree at duty is normal; degrees per pass signal trouble. In a closed loop the rise accumulates every circuit.
Formula
Pump Temperature Rise Calculator is a free pump temperature rise 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 Pump Temperature Rise Calculator
Liquid temperature rise across a running pump from power, flow and efficiency. The calculation implements ΔT = P·(1−η) / (ṁ·c_p) (ANSI/HI 9.6.3). A fraction of a degree at duty is normal; degrees per pass signal trouble. In a closed loop the rise accumulates every circuit.

Frequently asked questions
What formula does the Pump Temperature Rise Calculator use?+
It computes ΔT = P·(1−η) / (ṁ·c_p), per ANSI/HI 9.6.3. 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?+
A fraction of a degree at duty is normal; degrees per pass signal trouble. In a closed loop the rise accumulates every circuit.
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 Pump Temperature Rise 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.
