This manual provides installation, operation and maintenance instructions for the Edwards XDS46i and XDS46iC scroll
pump. The pump must be used as specified in this manual. Read this manual before installing and operating the
pump.
Important safety information is highlighted as WARNING and CAUTION instructions; these instructions must be
obeyed. The use of WARNINGS and CAUTIONS is defined below.
Warnings are given where failure to observe the instruction could result in injury or death to
people. The actual symbol shown varies according to the hazard.
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and/or process.
Introduction
The units used throughout this manual conform to the SI international system of units of measurement.
The following warning labels may be present on the pump and used throughout the product documentation:
Warning – an appropriate safety instruction should be followed or a caution to a potential hazard exists.
Warning – dangerous voltage. Indicates hazards arising from dangerous voltages.
Warning – hot surfaces. To indicate that the marked item can be hot and should not be touched without
taking precautions.
Warning – heavy object. Indicates the potential risk of physical injury and requires suitable lifting
equipment to move.
Warning – use protective equipment. Indicates that protective equipment must be used.
This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with Directive
2014/34/EU of the European Parliament and the Council of 29th March 2014 on the approximation of the laws of the
Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres.
(The ATEX Directive)
The ATEX Category 3 applies in respect of potential ignition sources internal to the equipment. An ATEX Category has
not been assigned in respect of potential ignition sources on the outside of the equipment as the equipment has not
been designed for use where there is an external potentially explosive atmosphere.
There is no potential source of ignition within the pump during normal operation but there may be potential sources
of ignition under conditions of foreseeable and rare malfunction as defined in the Directive. Accordingly, although
the pump is designed to pump flammable materials and mixtures, operating procedures should ensure that under all
normal and reasonably foreseeable conditions, these materials and mixtures are not within explosive limits.
Category 3 is considered appropriate for the avoidance of ignition in the case of a rare malfunction which allows
flammable materials or mixtures to pass through the pump whilst within their explosive limits.
Refer to Figure 1 for item numbers in brackets in the following descriptions.
The XDS pump is a compact, reliable vacuum pump which is suitable for use on vapour handling processes. It may be
used for some pumping applications involving corrosive substances and particulates; for information on pumping
flammable gases, please refer to Section 4.5 and contact Edwards for any further assistance.
The body of the pump includes a fixed scroll and an orbiting scroll. The orbiting scroll is controlled by the electric
motor through an eccentric cam on the motor drive shaft. The movement of the orbiting scroll, meshed with the
fixed scroll, forms successive crescent shaped volumes in the pump. Gas that enters the pump through the inlet is
compressed by the movement of the orbiting scroll and swept towards the centre of the fixed scroll. The compressed
gas enters the exhaust port near the centre of the stationary scroll and is exhausted from the pump through the
outlet.
The XDS is a dry vacuum pump, as all the bearings, with hydrocarbon lubricant, are isolated from the vacuum space.
The pump has an NW40 (item 1) inlet and inlet strainer.
