Gear Pumps

Precision Gear Pumps

Yeh-Der delivers custom ODM and OEM engineering solutions for miniature and precision gear pumps tailored to exact client specifications.

Core Specifications

  • Operating Voltage: DC 3–12V
  • Flow Rate: 10–150 ml/min
  • Operating Pressure: 4–10 PSI

Working Principle & Advantages Operating as a positive displacement pump, the unit utilizes dual precision-meshed gears to generate a continuous pressure differential:

  • Inlet: Gear unmeshing generates a vacuum to draw fluid into the chamber.
  • Outlet: Gear re-meshing creates continuous high pressure to discharge fluid.
  • Discharge volume correlates directly with rotational speed, ensuring stable, pressure-independent, and repeatable fluid metering.

Key Configurations

  • External Gear Pumps: Simple, robust architecture with high volumetric efficiency.
  • Internal Gear Pumps: Smooth, low-pulsation operation with ultra-quiet acoustic performance.

Target Applications & Industries

  • Medical & Healthcare: Medical auxiliary equipment, diagnostic fluid handling
  • Sanitation & Hygiene: Automated smart soap dispensers, disinfectant dispensing units
  • Thermal Management: Hot/cold water circulation loops, miniature fluid cooling systems
  • Industrial & Food Processing: Controlled metering of viscous media (lubricating oils, syrups, food-grade additives)

From prototype validation to full-scale automated production, Yeh-Der provides reliable and cost-effective fluidic solutions. Contact our engineering team for technical inquiries.
