What Is An Oil Free Vacuum Pump?
Oil free vacuum pumps, also referred to as an oilless vacuum pump or dry running vacuum pump, are essentially a type of vacuum pump that operates without the use of oil as a lubricant or sealing agent in the compression chamber. Instead of oil, oil free pumps utilize alternative materials or mechanisms for lubrication and sealing such as specialized coatings, dry running mechanism, or water as a sealant. Oil free vacuum pumps are preferred technologies in applications where oil contamination is a concern, such as food processing or pharmaceuticals. Oil free vacuum pumps offer benefits such as reduced maintenance, minimized risk of contamination, and increased sustainability compared to oil-sealed vacuum pumps.
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 Variable Speed Drive (VSD) to allow for greater process accuracy from the pump and reduce energy consumption further.
Clean Industrial Vacuum Solutions
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.
Low-maintenance solutions for industrial vacuums
If you’re looking to reduce maintenance and repair 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.
Low downtime, high reliability industrial vacuum systems
Unlike their 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.
Environmental, eco-friendly vacuum solutions
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 the manufacturing processes, lessening the user's impact on the environment from production of oil and disposal of waste oil.
Lower your total cost of ownership with our vacuum solutions
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.
