🔤 How to Read the Reference
- ✔ 3 to 7: number of stages (impellers); more stages, greater head
- ✔ M: single-phase, 230 V
- ✔ MA: automatic single-phase, with a float switch that turns the pump on and off according to the water level
- ✔ CEXT: external capacitor, no capacitor box, with 15 m of cable without a plug
- ✔ T: three-phase, 400 V
