A Brief Overview about Turbomolecular Pumps




There are various kinds of vacuum pumps available and used throughout the market. One that has gained notoriety in the last few years is known as a turbomolecular pump These pumps consist of a stator with turbine-shaped blades as static  blades and a rotor with rotating  blades. 

Workings of TMPs

The rotor blades rotate thousands of times, usually between 24,000 to 80,000 rotations per minute. This process creates and maintains vacuum. The principle that is followed by TMPs is that gas molecules will move in a specific and predicted direction when they come in forceful contact with  the solid surface of rotating blades. The blade collides with the gas molecules transferring to them the kinetic energy necessary to push them into the static part and then to the second rotating stage The gas moves through multiple compression stages, finally flowing through the exhaust port.. These pumps need a backing pump to work properly.. The performance of the pump depends on the rotational speed of the rotor.

Types of TMPs

Turbomolecular stages are particularly useful in  harsh processes where  dust or particles are present and can be coupled to drag stages to increase the pump compression capacity and get higher exhaust pressure (and as a consequence smaller and cheaper backing pumps) See Aglient turbomolecular pumps web site for more info. 

Advantages of TMPs

There are several reasons behind the popularity of TMPs

  • They are very easy to operate
  • Turbomolecular pumps require lower maintenance when compared with other kinds of vacuum pumps
  • Low vibrations are generated by TMPs (A benefit in many applications)
  • The operation is free of hydrocarbons 
  • No regeneration is required by these pumps
  • Constant pumping speeds is provided by turbomolecular pumps
  • These pumps are also quite reliable since they can be used constantly, even 24/7
  • They have a high tolerance to moisture
  • They can be very compact and can be combined with a dry primary pump very easily
  • They provide the cleanest conditions since they do not backstream oil into the vacuum system

Applications of  TMPs

Turbomolecular pumps are widely used in various environments.

  • Analytical instruments or R&D are some of the cleaner uses of TMPs
  • They are also sometimes used in the semiconductor industry for manufacturing in quite harsh conditions
  • These pumps are also used in deposition equipment
  • Sputtering equipment  vacuum coating plants often uses turbomolecular pumps 
  • They are used in particle accelerators
  • Manufacturing equipment for flat panel displays also makes use of TMPs

Numerous types of turbomolecular pumps are readily available in various sizes.

How Business Leaders Can Address the Climate Crisis




There is growing pressure for business leaders to take action for reducing their emissions and figuring out ways to deal with the causes and consequences of climate change. Many businesses are seeking a better understanding of the risks and opportunities of our changing climate and sustainability conditions. Furthermore, engaged customers, stakeholders, and suppliers, are putting increasing pressure on innovative and effective climate change and renewable energy solutions.          .

In order to make businesses more ecological, regenerative, and future-fit for taking the appropriate actions for climate change, we have consulted professionals in the field like Dr.      Anneloes Smitsman to help us get through this crisis.

Smitsman is a revered Dutch futurist, systems scientist, and award-winning pioneer in human development and system change who recently launched the EARTHwise Constitution for a Planetary Civilization, based on her work with living systems. She offers a diverse and inspiring range of systemic solutions that the professional sector requires for addressing the greatest challenges of the 21st Century. In particular for developing the necessary capacities and systems for co-creating thriving worlds and futures, based on new regenerative business models.

Smitsman’s career spans many domains, starting in law and political science, she then expanded her work to training business and educational leaders and companies in developing essential capacities for systemic transformation, innovation, corporate sustainability, and climate change preparedness.

Smitsman is also known for her work as an innovative leader and CEO of EARTHwise Centre, a non-profit company providing education, leadership, research, system design, and publications in social innovation, human and organizational development.

Smitsman is also unique in how she brought about revolutionary change in fields of    education, leadership, systems science, regenerative economics, sustainability, and more. And as a professional in the industry, here are a couple of things we have learned from her work for reducing your ecological footprint and creating more regenerative and sustainable business models.       

Developing Climate Action Plans

The first step is to create climate action plans for measuring the sustainability impacts of your business operations, based on measurements that account for essential sustainability thresholds, planetary boundaries, social ceilings, and fair allocations. Developing a genuine action plan, based on innovation and business leadership for climate change, requires going further than seeking to achieve standardized sustainability targets. Instead, set goals that challenge your organization to become regenerative ‘by design’ and thriving in terms of whole system impact, Smitsman explains. Focus on creating and distributing value beyond your own stakeholders or shareholder interests. Go further than trying to minimize harm, and instead provide leadership and capacities for business operations that focus on creating maximum goodness and whole system value.     

Smitsman also reminds us that leadership for the ‘commons’ requires innovation through collective decision-making with regards to fair and inclusive allocations of resource distributions and stewardship for the wellbeing of current and future generations.   Conventional market mechanisms that focus merely on carbon offsets and carbon trading, will not provide the incentives for the necessary systemic transformations that are required economically and politically.                    

Building a Culture of Awareness

 It is crucially important to add sustainability, regeneration, and thrivability as a part of your culture. To achieve this, you will need to expand your knowledge of the necessary energy and resource transitions, climate change adaptation and mitigation, low-carbon innovation, as well knowledge of the operational principles of living systems. There are many online courses available to help you prepare your business for the times ahead, and unlock new growth opportunities by developing a life-centered culture of leadership and innovation. This is also the focus of Smitsman’s leadership programs for business transformation and systemic innovation.

Working with Sustainable Suppliers

Knowing your partners is particularly important for companies with supply chains. You should take time to choose the best sustainable suppliers who focus on good environmental and sustainability practices. Furthermore, you can choose to reward suppliers who have outperformed your expectations by providing an improved sustainable service or product, as such encouraging continuous improvements for people, planet, and sustainable profits.
