Diffusion Pumps
Vacuum diffusion pumps are essential for creating high-vacuum environments in various industrial and research applications. They operate by heating a special lubricant (often silicone oils) to produce a high-speed jet of vapour, which directs gas molecules towards the pump’s exhaust. This process allows the pump to achieve very low pressures. They require a mechanical fore vacuum pump to operate.
Diffstak Vapour Pumps
The Mk2 Diffstak series offers compact and efficient diffusion pumps, designed to deliver exceptionally clean pumping without the need for extra traps, baffles, or liquid nitrogen cooling.
Choose from four different sizes, 63-100-160-250mm based on your requirements and for applications prioritizing high ultimate vacuum, all four pump sizes are available with unvalved collars. These collars eliminate the need for backing/roughing connections.
For critical applications demanding the utmost vacuum performance, consider the unvalved versions. These models feature 6- or 8-inch diameter flanges, sealed with copper compression gaskets (ConFlat). Achieve an ultimate vacuum of less than 2 x 10-10 mbar (2x10-8 Pa) using a low-temperature trap. Choose the Diffstak that best suits your vacuum system needs and enjoy reliable, efficient performance.
