Edwards nXDS10i Dry Scroll Vacuum Pump

Product details

Applications and selection

The Edwards nXDS10i is a dry scroll pump for laboratory vacuum, analytical equipment and suitable turbomolecular backing systems. Peak pumping speed is 11.4 m³/h, with an integrated controller and gas ballast for compatible vapour loads.

Key specifications

Ultimate pressure is a manufacturer test value, not a guaranteed pressure at the chamber. Pipe conductance, gas load, temperature and condition affect installed performance.

Documented configurations

Operating duty and pump-down

The nXDS10i permits continuous inlet pressure up to 200 mbar within the specified operating conditions. The recommended chamber volume describes pump-down from atmosphere. Larger volumes and extended high-pressure running require an application review because bearing life can be reduced. Size the connecting line and check the complete pumping-speed curve.

Controls and UK supply

The integrated controller provides local start/stop and standby functions, parallel control and RS232/RS485 serial interfaces. Remote cables and external TIC/TAG system controls are separately specified. For UK use, select the 230 V supply arrangement and separately ordered 2 m UK mains lead A50505000. Follow the manual’s electrical protection and connector requirements.

Gas ballast and process variants

The performance figures on this page describe the standard gas-ballasted model. Gas ballast improves suitable vapour handling while raising ultimate pressure. Chemically resistant C versions and R versions without gas ballast require separate selection; standard performance and compatibility must not be assumed for every process variant. Provide the gas composition, vapour load and cleaning agents for assessment.

Accessories and service

Select inlet filtration, catchpots, exhaust treatment, isolation and control cables for the system. These are optional unless listed in the quotation. Dry compression avoids sealing oil in the vacuum space; isolated bearing lubricant and replaceable tip seals still require maintenance. Keep ventilation and service access clear.

For a high-vacuum system, compare Edwards nEXT turbomolecular pumps and check the required backing pressure and gas throughput together.
