XDS Scroll Pumps

Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps, with pumping speeds of 5, 10 and 35 m3/hr, in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps.

 A72401905 - XDS5 3-phase 200/380/415/460 V set to high volts

Overview

The XDS pumps are an innovative design which use a bearing shield to isolate 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 XDS5 pump is designed for pumping condensable vapours and uses materials selected for a wide range of laboratory wet chemistry applications.

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.

A73001983 - XDS35i 100-120/200-230V, 1-ph, 50/60Hz with an IEC60320 connector, factory set to 230V

Overview

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.

A73101983 - XDS46i 100-120/200-230V, 1-ph, 50/60Hz with an IEC60320 connector, factory set to 230V

Overview

The XDS46i pump is a development on the XDS35i and thus shares many of the same features and benefits but with a peak speed boosted to 40m3/hr. The XDS46i is optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar making it ideally suited for LCMS and ICPMS applications requiring a higher pumping speed than that offered by the XDS35i. Recent improvements in tip seal technology have lead to reduced tip seal wear therefore giving a longer time between service interventions. The inverter drive controls the motor characteristics and ensures the pump always runs at optimum speed and allows the user to control the pump remotely.

A73201983
XDS100B 1-ph, 100-120/200-230V Set to 230V

Overview

The XDS100B is a scroll booster, with a pumping mechanism designed specifically for high pumping speed. Like all booster pumps, it needs to be used in conjunction with a primary pump and is ideally matched with Edwards XDS35i or XDS46i scroll pumps. The XDS100B is optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar making it ideally suited for ultra high throughput LCMS applications. The advanced pump design has resulted in virtually no tip seal wear thus reducing service intervention and maximising uptime.
The inverter drive allows the pump to be connected to a single phase supply and controls the motor characteristics and ensures the pump always runs at optimum speed and allows the user to control the pump remotely.

Technology
