Gear Pump With Magnetic Coupling Driver

The servo-driven magnetic stainless steel gear metering pump is a precision positive-displacement transfer device designed for leak-free operation. Its wetted parts are precision-machined from 304/316L stainless steel, and it utilizes a magnetic coupling drive mechanism that eliminates the need for traditional shaft seals, thereby completely preventing fluid leakage. Equipped with a servo-motor closed-loop speed control system, the pump enables precise gear speed regulation for high-accuracy quantitative transfer and metered dosing of chemical fluids; it is ideally suited for automated production environments involving toxic, volatile, or high-purity media where leakage is strictly prohibited.
The unit features a compact design, making it easy to integrate into equipment for adhesive dispensing, casting, filling, and chemical blending.

Advantages

1. Leak-free magnetic design: Features a magnetically coupled drive that eliminates the need for mechanical shaft seals, fundamentally preventing leaks and spills; suitable for volatile, toxic, or high-value chemical media, meeting environmental and safety standards.
2. Ultra-high metering precision: Combines positive-displacement gear metering with servo closed-loop control to achieve a metering repeatability of ±0.1%; ensures stable flow unaffected by pipeline pressure fluctuations, guaranteeing consistent mixing ratios for two-component materials.
3. Corrosion-resistant stainless steel construction: Wetted parts are made of 304/316L stainless steel, capable of handling medium-to-high viscosity, mildly corrosive fluids such as resins, curing agents, polyurethane adhesives, solvents, coatings, and additives; options for PEEK gears and Hastelloy components are available for highly corrosive applications.
4. Precise, controllable servo speed regulation: Servo motor offers rapid response and stepless speed adjustment; supports 0–10V, 4–20mA, and RS485 signal interfaces for PLC integration, enabling remote quantitative control within fully automated production lines.
5. Maintenance-free sealing structure: Eliminates wear-prone mechanical seals, reducing the frequency of seal replacements and lowering long-term maintenance costs; ideal for extended, continuous production operations.
6. Extensive configuration options: Available with thermal oil jackets for handling high-temperature, high-viscosity materials; customizable threaded or flanged connections; displacement ranges from 1.5 to 500 cc/rev, with pressure ratings up to 350 bar.

Suitable Media
