Laboratory devices demand precise and reliable fluid handling for accurate results. Micro gear pumps play a critical role in achieving this precision by delivering consistent flow rates. These micro gear pumps enhance efficiency by minimizing errors and ensuring stable operations. Their compact design and advanced technology make them indispensable in modern laboratory environments.
Working Principle of Micro Gear Pumps
Micro gear pumps operate based on a simple yet effective mechanism. These pumps use two interlocking gears to move fluid through the system. One gear is powered by a motor, while the other rotates freely. As the gears turn, they create small, sealed cavities that trap the fluid and transport it from the inlet to the outlet.
The design ensures a continuous and smooth flow of liquid. The teeth of the gears mesh together tightly, preventing backflow and leakage. This feature makes micro gear pumps highly efficient for precise fluid handling. The compact size of the pump allows it to fit into laboratory devices without taking up much space.
Another key aspect of their operation is the absence of valves. The gear mechanism eliminates the need for additional components, reducing the risk of mechanical failure. This design also minimizes maintenance requirements, making these pumps reliable for long-term use.
Micro gear pumps can handle a wide range of fluids, including chemicals, solvents, and biological samples. Their ability to maintain consistent flow rates under varying pressures makes them ideal for laboratory applications. The pumps also perform well in environments requiring high accuracy and repeatability.
Advantages of Micro Gear Pumps
