Motor
A 4-pole motor of at least 24.8 kW drives this pump at 1450 rpm on 50 Hz. On a 60 Hz supply a motor with the same poles turns it at 1740 rpm, where it takes 29.8 kW. Order that motor wound for 60 Hz and rated for at least that power.
| Motor | kW | rpm | Frame | Class | A at 400 V | Suppliers |
