Our Multiple External Control Digital Dosing Pump is a diaphragm metering pump powered by advanced algorithms (Huawei chip) and servo motors, delivering high dosing accuracy with an error margin within 0.24%. Designed for intelligent and automated performance, it ensures stable operation across a wide range of dosing applications.

Equipped with YLC pressure sensors, the system continuously monitors pipeline pressure, diaphragm movement, air bubbles, and potential blockages. This real-time monitoring helps maintain dosing accuracy and system safety. If any abnormal condition occurs, such as air ingress or pressure drops, the sensor triggers an on-screen alarm. For added convenience, the system also supports automatic exhaust to remove trapped air and restore smooth flow.

With its corrosion-resistant components and precise control system, this pump is well-suited for handling aggressive or sensitive fluids in industrial environments where reliability and chemical compatibility are critical.

Key Features

The Digital Dosing Pump is an advanced, high-precision solution built for smart, flexible chemical dosing. Featuring Condition Monitoring and Various Operating Modes, it delivers stable performance across dynamic process environments.

At the core of this system is a real-time Condition Monitoring function supported by high-speed pulse control with up to 18k resolution—allowing dosing precision within ±0.296%. Integrated sensors track pipeline pressure, diaphragm status, air bubbles, and flow anomalies. If irregularities occur, alerts are displayed instantly, and automatic adjustments are made to maintain dosing stability and protect the system.

To meet the demands of diverse industrial tasks, the pump offers Various Operating Modes, including time-based dosing, batch delivery, proportional control, and more. With its built-in AI algorithm module, it can perform advanced PID control for pH, liquid level, and concentration—without needing external PLC access.

Its modular integrated design simplifies installation and maintenance, while the communication interface ensures easy integration into broader control systems.

Function

Manual mode：It is the basic function ，You can set any flow rate you want through the control button，milliliter per minute. （press the button to start set and press it to finish）

Concentration mode：you can automatically proportion the concentration of dosing chemcial though this mode. It has three choices，the difference is precision higher（PPM million grade）Now we can enter into first one，you can set the original concentration of your liquid and the dilute concentration you want.

Impulse mode：In this mode，we can connect outside impulse signal though the interface input3，adjust the flow rate according to the impulse signal；if we set 1 milliliter/impulse signal，and we set 1 hz，the flow rate is 60 milliliter per minute.

Impulse control：It is always used for impulse water meter，our pump can automatically adjust the flow rate according to the flow rate change of impulse water meter.

Batch mode：you can set how much liquids you need to convey at one time

Current mode：0-20MA（milliampere）4-20MA

Pause-work：For example，you can set the working hours to 240minutes，and interval for 30 minutes，it means the pump will work for 4 hours and stop work for  30 minutes，when interval time over it will restart work （Cycle and continuous operation）according to the working time and intervals you set.

Weekly mode：You can set the start working time，continue working time（duration）and also the flow rate.You can set the maximum 20 in a week，from Monday to Sunday.

ROC mode：connect external control and start or stop the pump though the external button，digital control box
