In modern industrial dosing applications, precision, reliability and automation are no longer optional—they are essential. The Accurate Digital Dosing Pump is a diaphragm‐metering system driven by a high‐performance algorithm (based on a Huawei chip) and servo-motor actuation, delivering truly high precision with repeatability error margins as low as ±0.24 %.  It also features an integrated YLC sensor suite that continually monitors pipeline pressure, diaphragm condition, the presence of air bubbles and potential blockages. If an abnormal condition occurs, the system issues an alarm and can trigger automatic venting to restore proper operation.

Key Advantages & Features

Exceptional Accuracy and Wide Range

With a turn-down ratio of 1:700 and a minimum flow rate of just 0.06 L/h, this pump is capable of handling ultra-low dosing volumes as well as higher flows up to 42 L/h in standard mode.  The back-pressure rating reaches up to 7 bar, making the pump suitable for demanding metering situations.  The high precision and range flexibility ensure that processes sensitive to dosing errors—such as chemical reactions or treatment systems—can operate with confidence.

Smart Monitoring and Diagnostics

Equipped with YLC sensors, the pump continuously assesses key operating parameters: pipeline pressure, diaphragm health, air ingress, and blockage detection. This intelligent monitoring ensures the system remains within optimal performance conditions and provides early warning of issues that might compromise accuracy or uptime. 

Modular, User-Friendly Design

Installation and maintenance are simplified thanks to the modular structure, enabling quick set-up and minimal tools or downtime. The user interface is intuitive, allowing operators to switch between modes and adjust flow rates easily—even without deep technical knowledge. 

Versatile Operating Modes

This dosing pump supports multiple functional modes to suit a wide variety of tasks:

Manual mode: direct flow‐rate entry in mL/min.

Concentration mode: automatic proportioning of dilution from original to target concentration (ppm level).

Impulse mode: external pulse signal controls dosing volume (e.g., 1 mL per impulse).

Batch mode: fixed volume dosing at one time.

Current mode: 0–20 mA or 4–20 mA analog input control.

Pause‐Work mode: programmable work/interval cycles.

Weekly mode: scheduling over days of the week with flow/volume settings. 

These modes allow the pump to adapt to fixed dosing regimes, proportional dosing linked to process signals, or fully automated schedules.

Industry Applications

Water & Wastewater Treatment

Precise chemical dosing of coagulants, pH adjusters or disinfectants is critical in water and wastewater systems. With its high accuracy and automated modes, the pump enables consistent chemical injection, reduced waste, and better process control.

Chemical Processing & Petro-chemical

In chemical manufacturing, metering reagents, catalysts or modifier fluids often demands exact control of volume and concentration. The pump’s intelligent monitoring and wide range of modes make it a strong fit for corrosive fluids and complex dosing routines.

Mining & Flotation

Reagent dosing in mining (e.g. collectors, frothers) requires low flow, high precision and reliability under harsh conditions. The durable diaphragm design, sensor feedback and flexible control modes support these demanding applications.

Industrial Automation

In automated systems or plants moving toward Industry 4.0, the pump’s intelligent features, diagnostics and modular design integrate well into broader control systems, enabling remote monitoring, scheduled dosing and process optimization.

The Accurate Digital Dosing Pump offers a robust combination of high precision, smart control features, flexible operation modes and strong suitability across numerous industries. Whether you are addressing ultra-low flow dosing, handling challenging fluids or integrating into automated systems, this pump provides an advanced metering solution designed to deliver reliable performance, efficient operation and reduced risk of error. With the right selection and configuration, it becomes not just a pump—but a key component in achieving controlled, repeatable and optimized dosing processes.
