The drainage pump control box is a dedicated electrical device used to control the operation of drainage pumps, and is widely applied in scenarios such as basements, parking garages, sump pits, and sewage treatment tanks, where timely water removal is essential.
Its design centers on the core requirements of efficient drainage, safety and reliability, and automatic response.

Control Logic:
The control box typically works in conjunction with liquid level sensors (e.g., float switches) to monitor water levels and achieve fully automatic pump control.

When the water level reaches the pump start level, the drainage pump starts automatically.

When the water level drops to the pump stop level, the pump stops automatically to prevent dry running.

If the water level continues to rise and reaches the high-level alarm threshold, the system will trigger an alarm or start a backup pump to prevent overflow and flooding.
