FAQ - Your Guide to Understanding Micro Pumps

Welcome to BODENFLO! We understand choosing the right micro pump can be a challenging process. Below, we've compiled answers to some frequently asked questions to help guide you through the basics and technical details of micro pumps. If you have additional inquiries, our team is here to assist you!

 

1. What are the Different Types of Micro Pumps and Their Applications?

1. Micro Air Pumps:

  • Working Principle: Operate with a diaphragm or piston to create either pressure or vacuum.
  • Applications: Medical devices (e.g., blood pressure monitors), pneumatic controls, and inflating systems.

2. Micro Vacuum Pumps:

  • Working Principle: Function by expelling air to create negative pressure.
  • Applications: Analytical instruments, industrial vacuum systems, and suction-based machines.

3. Micro Liquid Pumps:

  • Working Principle: Move liquids using a diaphragm or rotary mechanism.
  • Applications: Cosmetic devices, chemical analysis equipment, and liquid dispensing systems.

 

2. How Do Micro Pumps Work?

Micro pumps rely on mechanical energy, typically from a motor, to create fluid motion:

  • Diaphragm Technology: Flexible diaphragms are used to draw in and expel fluids.
  • Piston Technology: Reciprocating pistons compress or push the medium.
  • Brushless Motors: Provide superior durability, efficiency, and higher performance for demanding applications.

 

3. How to Choose the Right Micro Pump for My Needs?

Selecting the perfect micro pump depends on several factors:

  • Medium: Gas or liquid?
  • Flow Rate: Do you need a specific flow rate (L/min or mL/min)?
  • Pressure/Vacuum Range: What are your required pressure or vacuum values?
  • Application: Does your application need features like quiet operation, high resistance, or corrosion-proof material?

 

4. What Are the Differences Between Brushed and Brushless Motor Micro Pumps?

1. Brushed Motor Micro Pumps:

  • Use carbon brushes to transfer current.
  • Ideal for low-duty or intermittent applications.

2. Brushless Motor Micro Pumps:

  • Use electronic controllers to operate without brushes.
  • Suitable for continuous or demanding applications.

 

5. What is the lifespan of BODENFLO micro pumps?

The lifespan of a BODENFLO micro pump depends on the motor type:

  • Brushed Motor Micro Pumps: Typically last 500-1,000 hours.
  • Brushless Motor Micro Pumps: Can last 3,000-10,000 hours, ideal for long-term or intensive applications.

 

6. What Maintenance Is Needed for Micro Pumps?

To maximize the life and performance of your micro pump, follow these maintenance tips:

  • Clean the pump and tubing regularly to avoid blockages or contamination.
  • Avoid running the pump at maximum rated pressure or flow for extended periods.
  • Store the pump in a clean, dry place when not in use.

 

7. Can Micro Pumps Handle Corrosive Liquids or Gases?

Yes! To ensure proper functionality, certain micro pumps are designed with corrosion-resistant materials. For example:

  • Chemical-resistant diaphragms or seals can manage aggressive chemicals.
  • PTFE and stainless steel materials can handle a wide range of corrosive substances.

8. Is Noise a Concern for Micro Pumps?

Most BODENFLO micro pumps are engineered to operate quietly. However, the noise level can vary based on the model and application. Our low-noise models are tailored for medical devices or beauty tools where silence is critical.

 

9. Do Micro Pumps Need Lubrication?

No. BODENFLO micro pumps are oil-free, which eliminates the need for lubrication. This feature keeps the medium (gas, air, or liquid) pure and contaminant-free, making them ideal for sensitive applications, like medical equipment or analytical devices.

 

10. What Are the Common Issues with Micro Pumps and How Can I Resolve Them?

1. Pump Isn't Working Properly:

  • Check if the power supply voltage matches the pump’s requirements.
  • Ensure the pump is properly connected, and the pipeline is not blocked.
  • Confirm that the pump has not exceeded its flow or pressure limits.

2. Pump Is Too Noisy:

  • Ensure the pump is securely installed.
  • Check if the diaphragm or piston is worn or loose.
  • Verify the pump isn’t running beyond its rated capacity.

 

11. How Much Power Does a Micro Pump Require?

Most BODENFLO micro pumps use DC voltage, typically ranging from 6V to 24V, depending on the model. Battery-powered options are also available for portable applications.

 

12. Which Industries Benefit from Micro Pumps?

Micro pumps are extremely versatile and used across diverse sectors, including:

  • Medical: Portable oxygen concentrators, blood pressure monitors.
  • Industrial: Vacuum systems, gas detection.
  • Cosmetic: Beauty and skincare devices.
  • Food & Beverage: Coffee machines, liquid dispensers.
