Brushed DC Motor Solutions for Micro Pump Applications

I. Working Principle

Micro DC pumps utilize motor-driven diaphragm reciprocating motion to create pressure differentials for fluid transfer. Key features include:

1. Compact DC motor design

2. Mechanical conversion of rotary to linear motion

3. Pressure differential-based gas/liquid transfer

II. Product Classification & Applications

1. By Function:

   • Air compression pumps: For compressed air output only

   • Vacuum/water pumps: Dual-function with dry-run capability

   • Specialized vacuum pumps:

     • Gas sampling pumps (light load)

     • Micro vacuum pumps (heavy load)
       
       

2. By Size:
