At the top of our pipeline pump range, frames from DN300 to DN400 move several hundred to over a thousand cubic metres an hour. They run at 1450 or 960 r/min, which keeps them quieter and slows wear.
| Model | Speed (r/min) | Flow (m³/h) | Head (m) | Motor (kW) |
|---|---|---|---|---|
| 300-235 | 1450 | 720 | 18 | 55 |
| 300-300 | 960 | 720 | 28 | 75 |
| 350-200 | 1450 | 1200 | 12.5 | 55 |
| 350-250 | 1450 | 1200 | 20 | 90 |
| 400-400 | 960 | 1080 | 12.5 | 55 |
