How do the micro vacuum pumps work?

The smallest vacuum pumps typically use a micro DC motor or piezoelectric driver to change the internal volume of the pump and achieve vacuum suction.

The most common type of micro vacuum pump is the micro diaphragm vacuum pump, which works by using a flexible diaphragm to expand and contract the pump chamber, causing gas to be drawn in and expelled to create a vacuum. When the diaphragm is pulled inward, the volume of the pump chamber decreases, causing the gas pressure inside to drop and create a negative pressure, resulting in a vacuum. When the diaphragm returns to its original position, the pump chamber expands, and the gas is expelled, creating positive pressure.

What types of the smallest vacuum pumps are there?

There are various types of the micro vacuum pumps, including rotary, piston, diaphragm, and among others. Each type has its advantages and disadvantages and should be chosen based on the application requirements.

Here’s a brief overview of the different types of the smallest vacuum pumps:

Miniature rotary diaphragm vacuum pumps, are usually round in appearance and do not last long, but are cheap. Usually used in the appliance industry, such as breast pumps, blackhead absorbers, etc.

Miniature Eccentric Diaphragm vacuum pumps, these pumps use a flexible membrane to create a vacuum. They are compact, oil-free, and have a low noise level. They are often used in applications that require a clean vacuum, such as medical devices and analytical instruments.

Micro Piston vacuum pumps: These pumps use a piston and cylinder to create a vacuum. They are simple in design, reliable, and can generate a high vacuum level. They are often used in applications that require a high vacuum and flow, such as beauty devices and vacuum automation.

How much vacuum level can the smallest vacuum pumps provide?

Vacuum pumps come in different sizes and types, each designed to meet specific vacuum level requirements. The smallest vacuum pumps, also known as micro vacuum pumps, are typically used in applications where small size and low power consumption are critical factors. Depending on the pump’s design and operating parameters, these pumps can provide vacuum levels ranging from a few millimeters of mercury (mmHg) to several hundred mmHg.

Because the internal structures of micro vacuum pumps vary among manufacturers, their parameters are not consistent. Therefore, it is essential to carefully review the parameters before purchasing.

For example, BODENFLO is a professional manufacturer of micro vacuum pumps, offering products with a vacuum range of -30kPa to -95kPa (225mmHg to 712mmHg) and suction flow range of 0.5 to 70L/min. To facilitate the selection process, please refer to the following article:

How do you install and maintain the micro vacuum pumps?


  • Before installation, carefully read and understand the instructions in the user manual to ensure proper installation and use.
  • When selecting an installation location, choose a dry, clean, and well-ventilated area to avoid the pump being affected by dust and moisture.
  • During installation, ensure that the interface between the pump and the piping is sealed and leak-free.

The design of mini vacuum pumps typically emphasizes user-friendliness and maintenance-free operation. However, some simple maintenance suggestions are provided below to help users maintain optimally:

  • pump performance. Regularly clean and replace filters to prevent dust and debris from entering the pump and affecting performance.
  • Regularly inspect the surface and interior of the pump to remove accumulated dirt and deposits.
  • Regularly check the seal of the pump to ensure stable vacuum inside.
  • If any abnormal conditions are found, such as noise, vibration, or leakage, stop using the pump immediately and contact the manufacturer or maintenance personnel.

How do you choose the smallest vacuum pumps?

When selecting the smallest vacuum pump for a specific application, there are several factors to consider. Here are some tips to help you choose the right micro vacuum pump:

Application Requirements: Consider the specific application and its requirements. This includes the necessary vacuum level, the size and weight of the pump, the required pumping speed, and the operating environment (e.g., temperature, pressure, and gas composition).

Pump Model and Specifications: Look for a micro vacuum pump that is specifically designed for your application. Check the pump’s specifications, including its pumping speed, ultimate vacuum level, power requirements, and noise level. Make sure the pump meets your application’s requirements.

Performance: Look for a pump that provides reliable and consistent performance. Consider factors such as stability, repeatability, and response time. The pump should be able to operate for long periods without requiring maintenance.

Reliability: Choose a micro vacuum pump from a reputable manufacturer with a track record of quality and reliability. Look for a manufacturer that offers warranties and after-sales support.

Price: Consider the price of the pump in relation to its performance and reliability. A lower-priced pump may save money upfront, but may not provide the necessary performance or reliability for your application.

Overall, it’s essential to choose a micro vacuum pump that is specifically designed for your application and meets your requirements for performance and reliability. Taking the time to research and choose the right pump can save time and money in the long run.
