Why should you consider using an oil-free vacuum pump?

A low energy solution

Oil-free vacuum technologies offer considerable savings in terms of overall energy efficiency. Oil-free vacuum pumps when combined with a VSD (variable speed drive) can reduce energy consumption by up to 50% in some applications compared to their oil lubricated equivalents. The Specific Energy Requirement or SER is the ratio of the power consumption (in watts) of the vacuum pump to the respective pumping speed (m3/h) in relation to the suction pressure (mbar abs.). Simply stated, how much energy is needed to move a certain amount of air from A to B. The compression principles of oil-free vacuum pumps can allow for a much reduced SER depending on the application requirements. Most oil-free technologies are compatible with a VSD to allow for greater process accuracy from the pump and therefore reduce energy consumption further.


A clean solution

If you have a process that requires stringent or lower level of contamination risk then oil free vacuum pump offer an efficient and assured solution. These vacuum pumps have been specifically developed to meet the needs of manufacturers that require only the highest air purity environments.


A low maintenance solution

If you’re looking to reduce maintenance costs an oil-free vacuum pumps would be the ideal solution. These pumps do not require the same level of maintenance as an oil-lubricated machine. There is no need to replace the oil and separator elements, which is regularly required and naturally results in higher operating costs over the pump’s lifetime.


A low downtime solution

Unlike there oil lubricated counterparts, oil-free vacuum pumps do not have to be removed to carry out essential maintenance servicing. This means there is little or no equipment downtime, as well as any indirect costs from lost production uptime.


An environmentally friendly solution

Oil-free vacuum pumps remove the cost of lubricants, waste oil disposal and labour. They also have the additional benefit of reducing oil consumption in our manufacturing processes, lessening the user’s impact on the environment from production of oil and disposal of waste oil.


A lower total cost of ownership solution

All of the above benefits allow oil-free vacuum pumps to offer outstandingly low total cost of ownership (TCO) over the lifetime of the pump. Reduced service and maintenance costs, combined with energy savings will reduce operating costs per machine. Although the initial investment of an oil lubricated solution may look appealing, the lifetime costs far outweigh those of a dry running machine in the long-term.

They facilitate the removal of moisture or solvents from pharmaceutical products or intermediates. Vacuum drying chambers or evaporators utilize vacuum pumps to create low-pressure conditions, which lower the boiling points of liquids, allowing them to evaporate at lower temperatures. By applying vacuum, moisture or solvents can be efficiently removed from substances such as active pharmaceutical ingredients (APIs), granules, powders, or coatings, ensuring the desired product quality and stability.

2. Filtration and Filtrate Recovery: Vacuum pumps are used in filtration processes for the separation of solid-liquid mixtures. Vacuum filtration systems typically employ a filter medium, such as filter paper or membranes, to retain solids while allowing the liquid portion to pass through. By applying vacuum to the filtration apparatus, the liquid is drawn through the filter medium, leaving behind the solids. Vacuum pumps facilitate efficient filtration, speeding up the process and improving product quality. Additionally, vacuum pumps can aid in filtrate recovery by collecting and transferring the filtrate for further processing or reuse.

3. Distillation and Purification: Vacuum pumps are essential in distillation and purification processes within the pharmaceutical industry. Distillation involves the separation of liquid mixtures based on their different boiling points. By creating a vacuum environment, vacuum pumps lower the boiling points of the components, allowing them to vaporize and separate more easily. This enables efficient separation and purification of pharmaceutical compounds, including the removal of impurities or the isolation of specific components. Vacuum pumps are utilized in various distillation setups, such as rotary evaporators or thin film evaporators, to achieve precise control over the distillation conditions.

Lyophilization is a dehydration technique that involves the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. Vacuum pumps create a low-pressure environment in freeze drying chambers, allowing the frozen product to undergo sublimation. During sublimation, the frozen water or solvent directly transitions from the solid phase to the vapor phase, bypassing the liquid phase. Vacuum pumps facilitate efficient and controlled sublimation, leading to the production of stable, shelf-stable pharmaceutical products with extended shelf life.

5. Tablet and Capsule Manufacturing: Vacuum pumps are utilized in tablet and capsule manufacturing processes. They are involved in the creation of vacuum within tablet presses or capsule filling machines. By applying vacuum, the air is removed from the die cavity or capsule cavity, allowing for the precise filling of powders or granules. Vacuum pumps contribute to the production of uniform and well-formed tablets or capsules by ensuring accurate dosing and minimizing air entrapment, which can affect the final product quality.

6. Sterilization and Decontamination: Vacuum pumps are employed in sterilization and decontamination processes within the pharmaceutical industry. Autoclaves and sterilizers utilize vacuum pumps to create a vacuum environment before introducing steam or chemical sterilants. By removing air or gases from the chamber, vacuum pumps assist in achieving effective sterilization or decontamination by enhancing the penetration and distribution of sterilants. Vacuum pumps also aid in the removal of sterilants and residues after the sterilization process is complete.

It’s important to note that different types of vacuum pumps, such as rotary vane pumps, dry screw pumps, or liquid ring pumps, may be utilized in pharmaceutical manufacturing depending on the specific requirements of the process and the compatibility with pharmaceutical products.

In summary, vacuum pumps play a vital role in various stages of pharmaceutical manufacturing, including drying and evaporation, filtration and filtrate recovery, distillation and purification, freeze drying (lyophilization), tablet and capsule manufacturing, as well as sterilization and decontamination. By enabling efficient and controlled processes, vacuum pumps contribute to the production of high-quality pharmaceutical products, ensuring the desired characteristics, stability, and safety.
