Stainless Steel Duplex Pump Controller - IP55 for Municipal & Irrigation Systems

Designed for dual pump management systems, suitable for scenarios requiring high flow stability such as municipal water boosting, agricultural irrigation, and small-scale industrial water circulation systems.

Robust Enclosure & Protection

Stainless Steel Enclosure for Harsh Environments The 3S smart water pump controller uses a high corrosion-resistant stainless steel enclosure, offering far greater durability than plastic housings. It is suitable for outdoor, coastal, and humid environments, extending overall service life.

IP55 Protection—Dust and Splash Resistant
A tight structure effectively prevents dust and moisture from entering the control system, reducing failure rates and making it ideal for pump rooms, wells, and other demanding environments.

13 Intelligent Protections The 3S smart water pump controller has integrated protections such as overload, undervoltage, locked rotor, dry-run, and signal fault detection to enhance operational stability and reduce equipment failure risks.

Flexible Control Logic

The duplex pump control panel features five common operating modes:

Single-Pump Operation: Backup pump handles entire load during maintenance

Duty/Standby Mode: Continuous operation with automatic failure switchover

Alternating Rotation: Balances usage time to avoid single-pump aging

Dual-Pump Simultaneous Start: Increases instantaneous capacity for peak demand

Timed Rotation Operation: Scheduled cycling for unmanned scenarios

The choice of core component brands directly impacts system safety.

ST MCUs execute precise protection logic.

HONGFA relays provide fast power cut response.

CHINT MCBs & AC contactors deliver fundamental electrical protection.

Together, these four core components ensure comprehensive safety for motors and the entire system.

1. Before installation, confirm the supply voltage matches the smart water pump controller and disconnect power to ensure safety.

2. Secure the duplex pump control panel to a wall or inside a control cabinet, ensuring adequate ventilation.

3. Connect the power, dual pump motors, and various signal lines according to the wiring diagram.

4. Configure the control logic (e.g., duty/standby, rotation) and timing parameters, then perform a power-on test.

Q1: How can I keep the running time balanced between two pumps?
A1: Set a timed rotation interval (e.g., switch every 12 hours). The controller will automatically alternate operation to balance usage and reduce excessive wear on a single pump.

Q2: If one pump fails, will the system shut down?
A2: No. The system automatically switches to the standby pump and issues an alarm, ensuring continuous operation.
