The XDS35i pump has an innovative bearing shield design that isolates the vacuum environment from all forms of lubricant, making it not only totally dry but also hermetically sealed. The shield also protects the bearing from any process vapors.

Gas ballast allows vapor 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.

The XDS35i has dozens of applications, including general clean pumping applications, beam lines and high energy physics, ultra-high speed centrifuges, cryogenics, freeze drying, rare gas recovery, and many more.

The Edwards XDS35i features a simple single sided scroll arrangement combined with an innovative motor and bearing design allows for easy field service with a minimum of special tooling for low cost of ownership and maximum up-time; an advanced interface provides a variety of traditional, analogue and digital control methods enabling remote control/monitoring via USB, RS232 or RS485; is lubricant-free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination; and it’s no atmosphere to vacuum shaft seals mean bearings are completely isolated, which prevents process attack and means the bearings run cooler and last longer.

Sound-deadening enclosure may be available, contact us for details.
