The pump motor operates under special conditions - moisture, round-the-clock operation, sometimes frequent starts. Let's look at how to choose a motor for a pump correctly.
Key parameters
- Power - in terms of performance and pressure of the pump with a reserve.
- Revolutions - must correspond to the pump (often 2900 rpm for centrifugal ones).
- Degree of protection - not lower than IP55 due to moisture.
- Mounting version—for pump design (feet or flange).
Special requirements
| Condition | Requirement |
|---|---|
| High humidity | IP55–IP66, moisture resistant insulation |
| 24-hour operation | Reliable bearings, cooling |
| Frequent starts | Soft start or frequency drive |
| Submersible pumps | Special sealed motors |
Frequent errors
- Reduced degree of protection - breakdown from moisture.
- Mismatch of speed - the pump does not reach the operating mode.
- Lack of protection against phase loss.
Pump motors are especially susceptible to breakdown of insulation from moisture, therefore when rewinding uses moisture-resistant impregnation. consultation with a specialist will help you choose the best option.
