Solenoid Metering Pump

An electromagnetic metering pump is a high-precision metering device driven by an electromagnetic coil (solenoid valve). It utilizes electromagnetic pulses to drive a diaphragm in linear reciprocating motion, thereby achieving precise control and quantitative delivery of liquid chemicals. Unlike traditional complex mechanical metering pumps, electromagnetic metering pumps are lighter and have a faster response time, making them a key component in modern water treatment, chemical dosing, and industrial precision dosing systems.

Our company's electromagnetic metering pumps have been optimized in both structure and performance design. The pump body adopts a modular layout, reducing the number of transmission components and making overall operation quieter and more stable. The electromagnetic drive unit has high-frequency response capability, enabling precise control of the stroke frequency and achieving stable flow output. Thanks to this simple and efficient drive method, the pump's control accuracy is particularly outstanding in the low flow range, making it suitable for continuous small-dose dosing applications.

Key parameters include: minimum flow rate of 0.4L/H, pressure: 16BAR, materials available: PP, PVDF, PVC, power: 12W, voltage: 220V (24V can also be customized). (Dimensions shown on the left side of the diagram)

In terms of material selection, it is equipped with a highly durable composite PTFE diaphragm, enabling it to withstand the erosion of various media such as acids, alkalis, and oxidants for extended periods without affecting performance. Our company has optimized the flow channel structure, reducing flow resistance, thereby achieving smoother media flow, higher overall metering stability, and a lower risk of clogging, thus reducing the daily maintenance burden on customers.

The electromagnetic metering pump is easy to operate. Users can quickly adjust the delivery frequency through a digital control interface. Some models also support external signal control, facilitating integration into automated water treatment systems, monitoring equipment, or central control units. Thanks to its low-energy-consumption design, the equipment maintains high-efficiency output even under prolonged continuous operation, without significant temperature increases or performance degradation due to continuous work.

1. Micro-addition in the food and pharmaceutical industries

Suitable for micro-addition scenarios such as flavorings, nutrients, fermentation additives, and cleaning agents (food-grade materials must be used).

2. Cooling water and boiler water treatment systems

Adding scale inhibitors, oxygen scavengers, bactericides, and pH adjusters to ensure efficient system operation and reduce corrosion and scaling.

3. Chemical dosing devices for online environmental monitoring equipment

Can be used with instruments such as COD and ammonia nitrogen analyzers to achieve automatic sampling and automated chemical dosing.

4. Laboratory, pilot-scale, and medium-scale equipment

Used for precise dosing of chemical media on research and experimental platforms. Simple to operate and easy to adjust, it is a commonly used precision liquid delivery device.

5. In addition, it has wide applications in electroplating plants, electronics factories (surface treatment wastewater), paper mills, printing and dyeing plants (wastewater dosing), and new energy and photovoltaic enterprises (electrolytes, chemical dosing).

1. Long Service Life and Low Maintenance Costs

Our company utilizes a thickened composite diaphragm, durable coil system, and low-impact drive, resulting in extremely low mechanical wear. Compared to traditional pumps, electromagnetic metering pumps can achieve long-term maintenance-free operation, significantly reducing operating costs.

2. Simple Operation and Precise Adjustment

The pulse frequency can be easily adjusted via an intelligent control interface, achieving precise flow control. Some models support external signal adjustment (e.g., 4–20 mA, water treatment system linkage, etc.), allowing integration into automated dosing systems.

3. Low Energy Consumption Design and Excellent Energy-Saving Performance

Electromagnetic drive itself is characterized by low energy consumption. Combined with our optimized control module, the equipment maintains low power consumption even during continuous operation, making it an ideal choice for applications requiring long-term continuous dosing.

4. Suitable for Professional Applications in Multiple Industries

This product is compatible with various media and can be used in industries such as electroplating, electronics, photovoltaics, new energy, batteries, chemicals, papermaking, printing and dyeing, surface treatment, and municipal wastewater treatment, meeting stringent dosage requirements.
