3S Iron Duplex Pump Control Box for Reliable Drainage & Water Supply

The iron intelligent duplex pump control box is specially designed for small drainage pump stations, automatic water replenishment of water tanks, and drainage of commercial buildings or site boundaries. It features dual-pump main-standby switching function, a robust structure, and is suitable for high-humidity and complex installation environments.

Basic Protection:

Overcurrent, undercurrent, overvoltage, undervoltage, and short circuit protection to prevent fault propagation.

Unique Protection:

Fault records and names shown on the LCD help users quickly identify issues, reduce troubleshooting time, and improve maintenance efficiency.

Signal loss:

Real-time monitoring of signal continuity with alarms to prompt users to check for abnormal signal devices, preventing production losses due to equipment downtime.

4-20mA transmitter error:

Real-time monitoring of transmitter malfunctions with timely alarms, enabling quick verification of sensor wiring to streamline commissioning, simplify maintenance, and enhance operational efficiency.

Water leakage:

Real-time monitoring with instant alerts to mitigate equipment damage and safety hazards, ensuring complete system protection.

Frequent start/stop:

Protects the motor from damage due to repeated starts and helps extend equipment life.

Pump stalled protection:

Prevents motor damage from rotor lock-up and provides real-time alerts for rapid fault resolution.

Blockage Protection:

Automatically detects pump blockages and triggers instant alerts for prompt maintenance.

Water shortage:

Dry run protection with sensor free

Anti-rust:

Auto-starts pump after long idle time to prevent impeller rust

Metal Enclosure Structure for Stability in Humid and Hot Environments

Made of thick cold-rolled steel plates assembled with high-temperature coating on the surface.

Resistant to moisture and corrosion, suitable for relative humidity up to 95%, preventing enclosure aging in high-humidity environments.

This structural advantage makes the single phase steel pump starter highly reliable in harsh conditions.

Stores internal 10 fault records to support quick troubleshooting.

Automatically handles alarms for abnormal signal input.

Automatically remembers the current operating status after power failure to ensure continuous operation after recovery.

Self-learning threshold setting intelligently determines the load status of the pump group to improve energy efficiency and response speed.

As a professional iron intelligent duplex pump control box, it integrates these intelligent features to reduce operational complexity.

Q1: Does the controller support remote communication?

A1: This model belongs to the local automatic control series. For remote communication, an RS485 module can be optionally added, or it can be upgraded to the IoT/WiFi intelligent version. Such scalable performance is consistent with the adaptable design concept of the single phase steel pump starter.

 

Q1: In a dual-pump system, if the signal cable breaks and causes system abnormality, how to troubleshoot?

A1: The iron intelligent duplex pump control box is equipped with signal loss detection and protection functions. When an abnormality occurs, it will alarm immediately and record fault information to quickly locate the problem source, reducing downtime caused by faults.
