Calculated curve · Total pressure · 1450 rpm
Calculated value – approximate
Calculated points (approximate)
| Q (m³/h) | Total pressure (Pa) |
|---|---|
| ≈ 393 | |
| ≈ 387 | |
| ≈ 377 | |
| ≈ 364 | |
| ≈ 347 |
The calculated shape uses catalogue ranges. Minimum flow is provisionally paired with maximum pressure and vice versa. These pairs and intermediate values are not confirmed by a factory curve.
