Due to oil-free technology, piston-vacuum pumps from Dürr Technik can be transported without any problems and mounted in all positions. Our oil-free piston-vacuum pumps are practically maintenance free. This is essential for installations where maintenance of the piston-vacuum pumps is often impossible or will be forgotten. There are very few operating costs as no oil-change and service is necessary. Therefore the application of the high quality, oil-free piston-vacuum pumps is also economically advantageous.
