Electromagnetic Metering Pump

The Electromagnetic Metering Pump is a high-precision metering and dosing device based on the principle of electromagnetic drive. It relies on the pulse force generated by an electromagnetic coil to drive the diaphragm in reciprocating motion, achieving precise liquid delivery. Compared to traditional motor-driven metering pumps, it has a simpler structure and more precise control, making it particularly suitable for applications requiring extremely high stability in dosing volume and corrosion resistance.

Our company's Electromagnetic Metering Pump employs advanced linear electromagnetic drive technology, eliminating the need for reversible motor rotation and gear transmission structures, resulting in virtually no mechanical wear. The core drive system has a fast response speed, and combined with an optimized pulse control algorithm, it can maintain a high metering accuracy within ±1% during long-term continuous operation. Simultaneously, the pump body is made of corrosion-resistant materials such as PVDF and PTFE, allowing it to withstand long-term exposure to acids, alkalis, and strong oxidants, ensuring stable performance and an ultra-long lifespan even in harsh environments.

In terms of user experience, this product supports fine flow adjustment and can be automatically controlled via a panel or external signals, facilitating integration into water treatment systems, dosing devices, or intelligent production lines. Its low energy consumption allows the equipment to maintain a stable and efficient working state during long-term operation, significantly reducing operating costs.

As a metering device that combines high precision, corrosion resistance, long lifespan, and ease of operation, the Electromagnetic Metering Pump is widely used in industries such as electroplating, electronics, chemicals, photovoltaics, new energy, batteries, papermaking, printing and dyeing, and municipal water treatment, and is a key component of modern precision dosing systems.

1. What is an Electromagnetic Metering Pump?

An electromagnetic metering pump is a high-precision metering pump that uses electromagnetic coil pulses to drive the reciprocating motion of a diaphragm, achieving quantitative liquid delivery. It features simple structure, high precision, and strong corrosion resistance.

2. What are the differences between an electromagnetic metering pump and a traditional motor-driven metering pump?

An electromagnetic metering pump eliminates the need for a motor and gear structure, directly driving the diaphragm with electromagnetic pulses. Therefore:

Less mechanical wear

Higher precision and faster response

Simpler adjustment (controlled by pulse frequency)

Lower maintenance costs

More suitable for small to medium flow rates and high-precision dosing applications.

3. What is the metering accuracy of an electromagnetic metering pump?

Our company's electromagnetic metering pumps maintain a metering accuracy within ±1% over long-term operation, suitable for industries with strict dosing requirements.

4. What chemical media can an electromagnetic metering pump deliver?

By selecting a suitable wetted material (such as PVDF, PTFE, 316L), the following media can be transported:

Acidic media (HCl, H2SO4, HF, etc.)

Alkaline solutions (NaOH, KOH, etc.)

Oxidizing agents (sodium hypochlorite, hydrogen peroxide)

Additives, auxiliaries, catalysts, etc. It can operate stably for extended periods even in highly corrosive environments.

5. How is the flow rate of the electromagnetic metering pump adjusted?

Flow rate control is achieved by adjusting the pulse frequency.

Some models support:

4–20 mA signal control

Pulse signal input

External controller linkage Facilitates integration into automatic dosing systems.
