Turbomolecular pumps

The powerhouse of high vacuum applications

Achieving and maintaining ultra-high vacuum (UHV) conditions is critical across various industries and research domains. Turbomolecular pumps, often abbreviated as turbo pumps or turbo vacuum pumps, are at the heart of these operations. Known for their precision and efficiency, these pumps are indispensable in applications ranging from semiconductor manufacturing to advanced scientific research.

If you’re looking for reliable and cutting-edge turbomolecular pumps, Acclon Technologies offers a range of high-performance solutions tailored to meet your specific requirements.

What is a turbomolecular pump?

A turbomolecular pump is a sophisticated device designed to create high and ultra-high vacuum environments. It achieves this by utilizing rapidly rotating blades to impart momentum to gas molecules, effectively moving them from the inlet to the exhaust. This precise mechanism not only reduces pressure in the vacuum chamber but also ensures a clean and uncontaminated environment, critical for sensitive industrial and scientific processes.

Unlike traditional pumps, turbomolecular pumps are oil-free, eliminating the risk of contamination. Their advanced magnetic bearing technology further enhances reliability by minimizing mechanical wear and vibrations.

What do turbomolecular pumps do?

Turbomolecular pumps are designed to effectively remove gas molecules from an enclosed space, creating a high or ultra-high vacuum environment. They achieve this through rapidly spinning rotor blades that accelerate and direct gas molecules towards the exhaust. This mechanism not only enables turbomolecular pumps to reach extremely low pressure levels but also ensures a stable and clean atmosphere. This makes them ideal for applications where even the slightest contamination is unacceptable, such as in sensitive production processes, scientific experiments, and aerospace technology.

What are the advantages of turbopumps?

The unique design and functionality of turbomolecular pumps provide several advantages over other vacuum solutions:

  • Exceptional vacuum performance: These pumps can achieve pressures as low as 10⁻¹¹ mbar, enabling ultra-high vacuum conditions required in many cutting-edge applications.
  • Contamination-free operation: The hydrocarbon-free design ensures that delicate processes remain unaffected by impurities.
  • High efficiency: With rapid pumping speeds and energy-efficient operation, turbomolecular pumps reduce operational costs.
  • Compact and versatile: The sleek design allows easy integration into complex systems, from laboratory setups to large industrial installations.

More information

How does a turbomolecular pump differ from a traditional vacuum pump?

Turbomolecular pumps operate using high-speed rotor blades, unlike mechanical pumps that rely on compression. This makes them ideal for achieving ultra-high vacuum levels.

What maintenance is required for a turbomolecular pump?

Most modern turbomolecular pumps, especially those with magnetic bearings, require minimal maintenance. Regular inspections and cleaning of the exhaust area are usually sufficient.

Can a turbomolecular pump be used in combination with other pumps?

Yes, turbo pumps are often paired with backing pumps (such as rotary vane or scroll pumps) to optimize vacuum performance.

What is the lifespan of a turbomolecular pump?

With proper usage and maintenance, these pumps can operate reliably for many years, often exceeding 10 years in standard applications.
