The Edwards XDS46i is a dry scroll vacuum pump engineered to provide oil-free and efficient vacuum solutions across various applications. Building upon the design of the XDS35i, the XDS46i offers enhanced performance, making it particularly suitable for processes requiring higher pumping speeds.

Key Features:

• Enhanced Pumping Speed: The XDS46i delivers a peak pumping speed of 40 m³/h (23.5 CFM), optimized for inlet pressures between 1 mbar and 10 mbar.
• Oil-Free Operation: Designed to be lubricant-free within the vacuum envelope, the pump ensures a clean and dry vacuum environment, preventing cross-contamination.
• Hermetically Sealed Bearings: The innovative bearing shield design isolates the vacuum environment from all forms of lubricant, protecting the bearings from process gases and enhancing durability.
• Inverter Drive Technology: Equipped with an intelligent drive system, the pump maintains consistent performance globally, offers overload protection, and allows for remote start/stop capabilities.
• Simple Maintenance: The single-sided scroll design allows routine maintenance to be performed in minutes, reducing downtime and ownership costs.

Performance Specifications:

• Ultimate Vacuum Pressure: Achieves an ultimate total pressure of 5 x 10⁻² mbar (4 x 10⁻² Torr).
• Water Vapor Handling: Capable of handling water vapor with a maximum inlet pressure of 40 mbar (30 Torr) and a maximum pumping rate of up to 240 g/h when using gas ballast.

Applications:

The Edwards XDS46i is well-suited for a variety of applications, including:

• Analytical Instruments:
– Liquid Chromatography-Mass Spectrometry (LCMS)
– Inductively Coupled Plasma Mass Spectrometry (ICPMS)
• Research and Development:
– Beam lines and high-energy physics experiments
• Industrial Processes:
– Coating technologies
– High-throughput applications

Design and Maintenance:

The hermetically sealed design, facilitated by the bearing shield, ensures that the vacuum environment remains uncontaminated by lubricants. This design not only prolongs the pump’s lifespan but also reduces maintenance requirements. Routine maintenance is straightforward due to the single-sided scroll design, allowing for quick servicing and minimal downtime.

The Edwards XDS46i stands out as a robust and efficient solution for applications demanding clean, oil-free vacuum environments with enhanced pumping speeds
