Overview of Suspension Vacuum Pumps

Suspension vacuum machines, like the LABA7 shock pumps, can help remove any air bubbles or contaminants from your shock absorbers, resulting in smoother ride quality and better handling.

Function of Vacuum Bleed Machine

Shock absorbers and forks have a limit after which their damping qualities fade. Then it is time to service them and change the oil. That is where the shock vacuum pump comes in.

Vacuum bleed pumps are essential for ensuring that air bubbles are removed from the damper, allowing the shock absorbers to function properly. By creating a vacuum in the damper, these pumps eliminate any air pockets that can cause aeration or cavitation.

Types of Suspension Vacuum Bleed Machine

When it comes to suspension vacuum pumps, there are various types available on the market to suit different needs and preferences.

  1. One type is the automatic vacuum bleed pump, which offers a convenient and efficient way to bleed air from your suspension system.
  2. Another option is manual vacuum bleed pumps, which require the operator to track pressure, vacuum, and time.
  3. For those who prefer a hands-on approach, there are manual bleeding processes that require more time and effort and can be very messy.

Choosing the type of suspension vacuum pump will depend on your requirements and level of expertise in maintaining shocks.

Automatic Vacuum Bleed Pump

What is an Automatic Vacuum Bleed Pump?

An automatic vacuum bleed pump is the perfect tool for maintaining the optimal performance of your suspension. This advanced device removes air bubbles from your shock absorbers efficiently and ensures a consistent vacuum density.

An automatic vacuum bleed machine takes the guesswork out of the process, making it easy to keep your dampers in top condition.

Advantages of Using an Automatic Vacuum Bleed Pump

An automatic vacuum bleeding machine offers unparalleled advantages when it comes to maintaining and tuning your suspension.

The ease of use provided by these pumps allows for quick and efficient bleeding of multiple dampers with just a push of a button. Not only does it ensure the correct bleeding process and consistency in the process, but it also allows for customizable presets to tailor the bleeding process to your specific needs.

With a plug-and-play design, these automatic vacuum bleed pumps are a must-have tool for any serious suspension enthusiast looking to optimize their setup.

How to Use an Automatic Vacuum Bleed Pump

The process is very straightforward – connect a shock to the LABA7 vacuum bleed pump, select settings, and press the button. That is it. Automatic LABA7 shock vacuum machines will do the rest.

The process takes about 10-15 minutes, but the actual vacuum bleed machine speed depends on your settings. For example, you can choose several vacuuming cycles.

We made several videos of how to use LABA7 automatic vacuum bleed pumps.

This list will expand over time. If you have questions, relating to shock absorber maintenance, contact us on social media.

Manual Shock Bleeding

Understanding Manual Shock Bleeding

This process involves manually removing air bubbles from the system and refilling it with fresh fluid to ensure optimal functionality. By utilizing a manual vacuum bleed, you can effectively purge any trapped air and prevent potential issues such as spongy brakes or inconsistent suspension response. It is important to follow proper procedures and use the correct tools to complete the manual vacuum bleed successfully.

Below we share a video on how to bleed shocks both manually and using an automatic vacuum pump.

Semi-automatic Shock Bleeding

The process is somewhat similar to automatic shock bleeding but requires the full attention of the operator. They also must understand and control pressure and vacuum levels, and the quantity of oil. What is being “automated” is the motor of the pump that sucks air and fills oil to a damper.

LABA7 Shock Pumps


Features of LABA7 Shock Vacuum Pumps

  • Fully automatic damper bleeding process.
  • Customizable presets allow you to service different types and sizes of dampers more easily and faster. All LABA7 pumps can save up to 8 different presets.
  • High-density vacuum ensures that all air is removed from the shock or fork before filling it with fresh new oil. Our pumps can reach a vacuum level as low as 2000 microns. A lower vacuum can damage the internal parts of the damper, for example, shims.
  • Altitude adjustment helps achieve desired results at any elevation.
  • Our suspension vacuum bleed machines are powerful enough to service multiple shocks at the same time.
  • PRO and MODULE pumps work with external vacuum pump tanks allowing to maintain different dampers without changing the oil in the pump.
  • Dedicated adapters for AUTO, MOTO, and MTB dampers to service shock absorbers of any type.

Benefits of Using LABA7 Shock Pumps

  • The damper vacuum bleed process is clean, quick, and effortless.
  • LABA7 automatic bleed machines are designed to remove all air from the damper.
  • Reduces gas content to a minimum to avoid aeration and cavitation.
  • Can operate with all types of oil.
  • Saves your time, money, and effort.
  • Works seamlessly with other LABA7 tools for shocks.

Maintenance Tips for LABA7 Shock Pumps

After servicing 350 dampers, the pump will display a notification to check the oil level in the pump. Download the manual to learn how to do it.

That is about it.

How to Bleed Shock Absorbers

Importance of Bleeding Shock Absorbers

When it comes to maintaining the performance, reliability, and safety of your suspension system, one crucial step that should not be overlooked is bleeding shock absorbers. Properly bleeding your shock absorbers ensures that any air bubbles that may have built up in the system are removed, allowing for consistent and smooth operation. This process helps to optimize the overall performance of your suspension system, providing you with a comfortable and controlled driving experience. Additionally, bleeding shock absorbers can also extend the lifespan of your suspension components, ultimately promoting safety on the road. By prioritizing this maintenance task, you can ensure that your suspension system operates at its best, enhancing your overall driving experience.
