Edwards XDS35i Scroll Vacuum Pump, 1-phase 100-120/200-230V - A73001983

XDS35i 100-120/200-230V, 1-ph, 50/60Hz with an IEC60320 connector, factory set to 230V

The XDS35i pump has an innovative bearing shield design that isolates the vacuum environment from all forms of lubricant, not only making it totally dry but hermetically sealed. The shield also protects the bearing from any process vapours.
Gas ballast allows vapour to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps. The inverter drive controls the motor characteristics and ensures the pump always runs at optimum speed.

Technology

Scroll pumps use intermeshing fixed and orbital scrolls to form non-contacting, crescent shaped gas pockets that are continuously compressed by the orbiting action. This means that, unlike oil-sealed rotary pumps, there is no sealant or lubricant required in the swept volume of the pump.

Applications

• Clean pumping applications
• Automotive
• Beam lines and high energy physics
• Centrifuges, ultra high speed
• Coating

Features and Benefits

• Lubricant-free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination
• No atmosphere to vacuum shaft seals means bearings are completely isolated, this prevents process attack and means bearings run cooler and last longer
• No oil changes required eliminating costs of contaminated oil disposal
• Simple single sided scroll design means maintenance is done in minutes for low cost of ownership and maximum up-time
• Inverter drive for consistent pumping speed at 50/60Hz
