Horse Power Calculator

To determine the maximum natural brake or reduction in horse power created when the Cycle Stop Valve chokes back your pump:

1. Enter your minimum expected flow or demand. When using a Cycle Stop Valve, this minimum flow is determined by the built-in minimum flow for your particular model valve. (ie: 1, 2, or 5 GPM)
2. Enter the head in feet that your model pump builds at the minimum flow.
3. Enter the efficiency for your pump at the minimum flow.
4. Click "Calculate" to find BHP.
5. You can also figure your maximum HP. Repeat steps 1-4 using the maximum flow expected instead of the minimum flow. This calculator can be used for all flows in between as well.
