Diffusion Vapour Vacuum Pumps

Our Diffusion Vapour Vacuum Pumps category offers a selection of high-quality, second-hand pumps designed for achieving high to ultra-high vacuum levels in laboratory and industrial applications. These pumps use a stream of vapor (typically oil or mercury) to direct gas molecules from the vacuum chamber into the pump, making them ideal for processes such as vacuum coating, metallurgy, and electron microscopy.

Equipment undergoes varying levels of testing, including functionality checks and vacuum performance assessments, ensuring reliable and efficient solutions for your high-vacuum requirements. Perfect for labs and industries needing robust, high-performance vacuum systems for advanced research and industrial processes.
