Reliable Protection & Stable Performance:

Built-in short circuit, overload, phase loss, and locked rotor protection automatically shuts off power under abnormal conditions, preventing damage and extending pump life. Dual AC contactors provide precise current control and ensure smooth operation even under high loads.

Ultra-High Water Level Alarm:

In auto mode, dual float switches monitor the water level. When it exceeds the preset limit, a bright warning light activates and a loud 85 dB+ alarm sounds—clearly audible in noisy environments. The pump turns on automatically to drain water until levels return to normal, helping prevent overflow and flooding.

Manual/Automatic Dual Pump Control:

Easily switch between manual and automatic operation using the front-panel knob. In auto mode, the float switches manage the system hands-free. In manual mode, you can select which pump to activate—ideal for alternating operation or using one as backup, giving you greater control and flexibility.

Durable & Weather-Resistant:

Made with cold-rolled steel, the enclosure offers excellent resistance to impact, corrosion, and wear. A raised-edge waterproof design and sealing gasket effectively prevent rain and dust intrusion, ensuring dependable performance even in harsh outdoor conditions.

Versatile Applications:

With features like fault indication, alarm alerts, and intelligent pump control, this unit is perfect for sump drainage, water tank refilling, and other water level control tasks. Whether for home wells, irrigation, or pump stations, the OELFFOW Control Box delivers efficient and safe water management.
