In modern industrial and water-treatment processes, accurate chemical dosing is a key factor in ensuring safe, efficient, and cost-effective operation. The high-precision digital dosing pump introduced here is engineered specifically to meet demanding metering challenges—with features that elevate it well beyond standard diaphragm pumps.

Exceptional Accuracy and Turn-Down Range

At the heart of this pump is a diaphragm metering mechanism driven by a servo motor and a high-performance control algorithm (noted as “Huawei chip” architecture). The result is a remarkably tight repeatability error (within ±0.24% under typical conditions) and a wide turn-down ratio (e.g., 1 : 1000 in one model) with flow range from as low as 0.06 L/h up to 60 L/h in standard mode (for model E01A 060-04) and up to 30 L/h or 15 L/h in slow-modes for higher viscosity fluids. These parameters allow the pump to handle fine metering tasks and also respond when process conditions vary dramatically—with minimal recalibration required.

Smart Monitoring and Automation

Beyond precision mechanics, this pump includes built-in YLC sensors which continuously monitor key parameters—pipeline pressure, diaphragm motion, presence of air bubbles, and pipeline blockages. When an abnormal condition is detected (for example, air ingress into the line), an alarm is displayed and automatic air-exhaust can be triggered. This level of intelligence significantly reduces the risk of dosing errors, downtime or chemical wastage.

Versatile Operating Modes and Connectivity

The pump offers a broad suite of operating modes that adapt to various process control needs: manual mode for straightforward metering; concentration mode for automatic proportioning of dosing chemicals (including PPM-level precision); impulse mode (flow proportional to external pulses); batch mode; current control mode (0-20 mA or 4-20 mA); pause-work mode (work/interval cycling); weekly mode (scheduled dosing across days); and ROC (remote on/off control). In addition, wireless connectivity (Wi-Fi / 4G) enables remote monitoring of flow rates, equipment status, wear-part life and cost reports. This combination of modes and connectivity makes the pump ideal for both standalone installations and integrated automation systems.

Built-in Reliability for Harsh Environments

Recognizing the challenges of viscosity, clogging, and continuous chemical service, the pump incorporates anti-clogging features, network monitoring of the piping, a flushing function, and materials selected for extended wear life.  It is capable of handling higher viscosity fluids by using slower mode settings and appropriate wetted materials. Optional flow components made of different materials may be specified to extend the temperature range of the medium. 

Applications and Process Benefits

Thanks to its fine control, robust monitoring and smart connectivity, this pump is particularly suitable for applications such as wastewater treatment (coagulants, pH adjusters), chemical processing (reagents, dosing of corrosives), mining flotation (collectors/inhibitors), food & beverage or pharmaceutical additive dosing (when paired with appropriate materials and hygiene design). Its high precision reduces chemical waste and ensures consistent process performance. The connectivity and alarm features support predictive maintenance, minimizing unscheduled downtime.

The High-Precision Digital Dosing Pump brings together modern servo control, digital logic, extensive monitoring and flexible modes—delivering high accuracy, operational reliability and integration into smart systems. For engineers and operators faced with stringent dosing requirements, variable process conditions or future-proofing automation, this pump stands as a powerful solution. Choosing such a system supports not just immediate dosing needs, but also long-term maintenance efficiency and process stability.
