Introduction
Medical technology is advancing faster than ever, and with this rapid progress comes a rising demand for fluid-handling components that offer precision, durability, and exceptional cleanliness. Among the numerous pump types available today, the micro magnetic gear pump stands out as a powerful and compact solution designed for high-accuracy performance in medical and laboratory devices.
Unlike conventional pumps that rely on direct mechanical contact, micro magnetic gear pumps utilize magnetic coupling to transfer torque internally. This design ensures a hermetically sealed chamber, minimizing contamination and enabling ultra-stable micro-flow operation essential for sensitive healthcare applications.
What Is a Micro Magnetic Gear Pump?
A micro magnetic gear pump is a miniature, positive displacement device driven through a magnetic field instead of a mechanical shaft. Inside the pump, two small gears rotate to deliver consistent and pulse-free flow. The magnetic coupling isolates the motor from the fluid path, creating a closed system ideal for sterile environments.
