🔤 How to Read the References
- ✔ 500, 501 and 502: have the same body, the same dimensions and the same 5 HP motor; they differ in the impeller and the curve: the 502 delivers the greatest head (see the table)
- ✔ Without letters: three-phase 400 V, supplied without a float switch: connected via a control panel, using the panel's float switches
