WARNING

1Introduction

1.1 Scope of this manual

This manual provides installation, operation and maintenance instructions for the Edwards XDS35i, XDS35iC, XDS35iE, and XDS35iCE scroll pumps. 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/Caution – 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 appropriate protective equipment must be used.

A730-01-880 Issue L

Introduction

1.2 ATEX directive implication

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.

Introduction

1.3 Description

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 their hydrocarbon lubricant, are isolated from the vacuum space.

The pump has an NW40 (item 1) inlet and inlet strainer.
