Vacuum boosters increase both the pumping speed and final pressure of vacuum pumps, which can significantly improve the performance of vacuum systems, sometimes up to ten times.
They operate on the proven Roots principle: two synchronously rotating rotors inside the casing transport gas between themselves and the casing, without contact between themselves or with the casing. This means that no lubricants or operating fluids are required in the compression chamber.
The rotors are driven by gears at the ends of the gearbox, separated from the compression chamber. This ensures accurate synchronous alignment of the rotors.
Vacuum boosters can operate with or without a mechanical bypass valve. Without a bypass valve, the maximum differential pressure between inlet and outlet must be monitored during operation. Boosters with a bypass valve divert a portion of the pumped medium, automatically reducing the differential pressure and protecting the booster from overload.
Vacuum boosters are particularly effective when integrated into systems that require high gas throughput. This makes them indispensable in industrial applications where fast and efficient vacuum must be generated over large volumes. With increased speed and pressure, these systems can speed up production processes, resulting in higher overall efficiency and productivity. In addition, vacuum boosters offer the advantage of being able to reduce the load on primary vacuum pumps, leading to lower maintenance costs and longer life of the entire vacuum system.
The flexibility of vacuum boosters, with or without a mechanical bypass valve, allows companies to fine-tune their systems to meet specific operational needs. In applications where constant pressure and flow rate are critical, such as in chemical processing or wastewater treatment, the use of a booster with a bypass valve can be particularly advantageous. This system provides automatic pressure adjustment, ensuring stability within the process and minimizing the risk of system failure due to pressure buildup.
