Many pumps can be normally adjusted by the variation of the working frequency which affects the maximum pump flowrate and maximum pressure gain as:
| LaTeX Math Block |
|---|
| q_{\rm max} = q^*_{\rm max} \cdot \frac{f}{f^*} |
| | LaTeX Math Block |
|---|
| \delta p_{\rm max} = \delta |
|
pp^*_{\rm max} \cdot \left( \frac{f}{f^*} \right)^2 |
|
