Submersible Sewage Pump System
Reliable Wastewater Pumping with Duty and Standby Pumps
For wastewater drainage applications, reliable operation requires more than a suitable pump. Liquid-level control and automatic standby switching are also important for maintaining system operation.
Application Specifications
The proposed system is based on the following requirements:
| Parameter | Specification |
|---|---|
| Pump model | 65WQ20-30-4 |
| Flow rate | 20 m³/h |
| Head | 30 m |
| Motor power | 4 kW |
| Power supply | 400 V, 3-phase, 50 Hz |
| Pump material | Cast iron |
| Protection rating | IP68 |
| Control cabinet | IP55 |
How Does the Automatic Control Work?
Each set includes two submersible sewage pumps and one shared control cabinet.
High liquid level: The duty pump starts.
Very low liquid level: The duty pump stops.
Pump failure: The system switches to the standby pump, subject to the confirmed control configuration.
The proposed system includes liquid-level switches, power cables, control cables, accessories, and a 4 kW variable frequency drive. The control cabinet has no touchscreen.
Four sets would require eight pumps and four control cabinets, subject to final confirmation.
