What is a Vacuum Booster?

Vacuum Booster

A vacuum booster, also called a mechanical booster pump, helps vacuum systems work better by making them pump faster and more efficiently. It uses positive displacement mechanisms like Roots blowers, which have rotating lobes to move air or gas through the system. This lets the vacuum system reach lower pressures and handle more gas. Mechanical vacuum boosters are important for applications that need quick evacuation and deep vacuum levels. They reduce the work the main vacuum pump has to do, making it last longer and improving the whole system's reliability. They're also made to last in tough industrial conditions.

Features and Specifiactions of Vacuum Booster


Significantly increases the overall pumping speed of the vacuum system, allowing for faster evacuation times.
Enhances the ability to achieve lower ultimate pressures, which the primary pump alone cannot reach.
Utilizes rotating lobes, typically in a Roots-type blower configuration, to move large volumes of gas efficiently.
Reduces the workload on the primary vacuum pump, extending its operational life and improving system reliability.
Built to withstand harsh industrial conditions with durable materials and robust design.
Improves the overall energy efficiency of the vacuum system by optimizing the load distribution between the booster and the primary pump.


Typically ranges from 100 to 20,000 cubic meters per hour (m³/h), depending on the model and application.
Can achieve pressures down to 0.01 mbar when combined with a suitable backing pump.
Usually between 1.5 kW to 75 kW, varying according to the size and capacity of the booster.
Commonly ranges from DN 40 to DN 300, depending on the model and application requirements.
Designed to operate effectively within a temperature range of -10°C to 40°C.
Constructed from high-grade materials such as cast iron, aluminum, and stainless steel to ensure durability and resistance to corrosion.
