Stage Configurations - Choose Your Model
The Grundfos CM 10 series is available in multiple stage counts. More stages = higher pressure (head) at roughly the same flow rate (~55 GPM at the best efficiency point). Pick the configuration that matches your required discharge pressure:
| Model | Stages | Head @ BEP | Motor HP | Phase | Material Number |
|---|---|---|---|---|---|
| CM 10-2 | 2 | ~140 ft (60 psi) | 3.4 HP | 3-phase | 97568516 |
| CM 10-3 | 3 | ~210 ft (90 psi) | 5.4 HP | 3-phase | 97524349 |
| CM 10-4 | 4 | ~280 ft (121 psi) | 8.4 HP | 3-phase | 99059793 |
| CM 10-5 | 5 | ~350 ft (151 psi) | 8.4 HP | 3-phase | 98694666 |
