Vacuum Component Manufacturing

CNC Manufacturing Capabilities

At Pfeiffer Vacuum Valves & Engineering, our skilled designers and engineers are committed to delivering top-quality vacuum system components tailored to your unique application needs. Leveraging advanced computer numerically controlled (CNC) tube bending technology, we offer:

• Vacuum Flanges and Fittings
• Vacuum Chambers
• Traps and Filters
• Viewports, Shutters, and Doors
• Feedthroughs
• Vacuum Isolation Valves
• Custom Fabrication and more!

Our CNC tube bender enables precise forming of elbows and custom exhaust weldments, facilitating multiple compound angle bends in a single tubing piece. We offer customization options for tubing diameters, accommodating both standard and metric specifications.

Custom Weldments and Vacuum Components

With in-house manufacturing capabilities, our team can assemble complete one-off systems to your specifications, including chambers, frames, pumps, gauges, valves, and manipulators.

Vacuum Manufacturing Materials Selection

We utilize only the finest-grade materials for vacuum component manufacturing, considering factors such as vapor pressure, permeability, and corrosion resistance. Our materials include select grade 304 stainless steel tubing, spheres, or roll-ups, with options for 304L, 316L, or 316LN if required. Flanges and baseplates are meticulously crafted from specially treated 304 stainless steel to meet ASTM A-240 standards.

Custom Vacuum Fabrication

Our state-of-the-art CNC machining equipment ensures consistent, high-quality parts production. We employ advanced techniques such as die-formed ports using the pulled-port method and orbital welding for precise weld penetration. Welding procedures adhere to ASME Section IX standards, with Weld Procedure Specifications on file for reference.
