    Applications of RK-3035 Micro DC Motor in Diaphragm Pumps/Vacuum Negative Pressure Pumps/Inflators/Aquarium Air Pumps

    Model: RK-3035SA-23184
    Rated Voltage: DC 6V
    Load Capacity: 40g-cm | Stall Torque: ≥325g-cm
    No-Load Speed: 4300±300 RPM | Load Speed: 3700±260 RPM

    Key Application Fields

    1. Diaphragm Vacuum/Negative Pressure Pumps

      • With a load speed of 3700 RPM and stall torque of 325g-cm, it efficiently drives diaphragm reciprocating motion to quickly generate negative pressure, suitable for:

        • Small vacuum packaging machines

        • Medical suction devices

        • Laboratory vacuum systems

    2. Miniature Inflators (DIY Inflator)

      • Low starting voltage (≤1.5V) ensures quick response, making it ideal for:

        • Balloon/air mattress inflators

        • Pneumatic tool auxiliary inflation

        • Portable outdoor inflation devices

    3. Aquarium Air Pumps

      • Low-noise design (≤55dB at 10cm) prevents disturbance to aquatic life, while stable 6V/480mA load operation ensures long-term reliable oxygen supply.

    4. Industrial Micro Starters

      • High torque output enables driving small mechanical structures, applicable in:

        • Automated valve triggering

        • Small conveyor belt drives

        • Instrument reset mechanisms

    Product Advantages

    ✅ High Power – Stall torque of 325g-cm easily overcomes pump resistance
    ✅ Low Power Consumption – Rated load current only 480mA, energy-efficient
    ✅ Instant Start/Stop – Starting voltage ≤1.5V, ultra-fast response
    ✅ Quiet Operation – ≤55dB noise level, suitable for noise-sensitive environments


    Typical Use Cases
    ▸ Medical Devices: Dental suction units, negative pressure wound therapy systems
    ▸ Home Appliances: Portable vacuum cleaners, smart toilet vacuum generators
    ▸ Industrial Automation: Pneumatic component test benches, small automated actuators

    Customization Options Available! (Voltage, shaft length, IP rating, etc.)


    Note: Optimal performance requires matching with a gearbox or transmission mechanism to adjust torque/speed ratio.
