Peristaltic Pumps

  • Structure: Consist of a flexible tube compressed by a rotating wheel to move fluids in a peristaltic motion.
  • Benefits: Their design ensures that the fluid only contacts the tubing, not the pump mechanism, significantly reducing contamination risks—ideal for sterile medical applications and sensitive chemical processes.

Micro Gear Pumps

  • Structure: Utilize small, interlocking gears to transport fluid with a smooth, continuous flow.
  • Benefits: Highly effective for chemical processing due to their resistance to corrosion and the ability to handle high-viscosity fluids, making them suitable for water treatment and precise chemical dosing.

Oilless Piston Air Vacuum Pumps

  • Structure: Use a piston within a cylinder, designed to operate without oil, creating a vacuum and pressure without contamination.
  • Benefits: These pumps are essential in applications requiring clean and hygienic operations, such as in dental offices and medical environments where sterility is a must.

Brushless DC Centrifugal Pumps

  • Structure: Powered by a brushless DC motor that drives a centrifugal impeller to move fluid efficiently.
  • Benefits: Known for their long service life and high efficiency, these pumps are excellent for cooling electronic components and circulating coolants in advanced medical devices.

Piezoelectric Pumps

  • Structure: Utilize piezoelectric materials to create precise vibrations that pump fluids through microchannels.
  • Benefits: Extremely compact and low-power, these pumps are perfect for microfluidic applications where space and energy use are critical, such as in wearable medical devices.

Each type of miniature pump offers distinct advantages, making it crucial to choose based on the specific needs of your application. Whether you require a pump for a medical device, a piece of laboratory equipment, or an industrial machine, understanding these types will help you select the most suitable option to ensure efficiency, reliability, and optimal performance.
