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.

Features and Benefits

• Diffusion Pump: The heart of the system, responsible for efficient pumping.
• Water-Cooled Baffle: Ensures optimal cooling during operation.
• High-Vacuum Isolation Valve: Part of the inlet-flange, configurable for manual or pneumatic operation.
• Roughing Connection: Facilitates the initial pumping process.
