In the table, each column is a flow rate in m³/h and the value is the head in metres. For weights with two measurements, the first is for the single-phase version.
🔤 How to Read the Reference
- ✔ 3, 4, 5, 6, 8, 10: number of stages (impellers); more stages, greater head
- ✔ M: single-phase, 230 V
- ✔ T: three-phase, 400 V
