WARNING

1Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards XDS5 and XDS10 dry pumps. You must use the XDS pump as specified in this manual. Read this manual before you install, operate and maintain the XDS pump.
Important safety information is highlighted as WARNING and CAUTION instructions; you must obey these instructions. 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.
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated equipment and process.
Introduction
Throughout this manual, page, figure and table numbers are sequential. The following IEC warning labels appear on the pump:
Warning - refer to accompanying documentation.
Warning - risk of electric shock.
Warning - hot surfaces.

Introduction

1.2 ATEX directive implications

This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with
Directive 94/9/EC of the European Parliament and the Council of 23 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 o f 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 pote nt ial sources of ignition under conditions of predicted 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 predicted 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 flammab le materials or mixtures to pass through the pump while within their explosive limits.
When flammable materials are present within the equipment you must:
Not allow air to enter the equipment.Ensure the system is leak tight.
For further information, please refer to the back page of this instruction manual for the contact details of your nearest Edwards.

Introduction

1.3 Description

The XDS pump is shown in Figure 1. 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. The XDS
pump 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 sc roll and an orbiting scroll. The orbiting scroll is driven 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. Ga s which 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 pump is a dry vacuum pump, as all the bearings, with their hydrocarbon lubricant, are isolated from the vacuum space.
The inlet of the pump is fitted with a removable inlet strainer which prevents the entry of debris into the pump. The pump mechanism is driven directly by a single- phase or three-phase electric motor. Single-phase motors are
fitted with an on/off switch (7) and a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the motor cools down, the device resets and (unless you have incorporated suitable control equipment which must be manually reset), the motor will restart.
The pump is air-cooled by a fan mounted at the opposite end to the motor. The pump is mounted on a baseplate on rubber feet. Details of suitable vibration isolators and other accessories are
provided in Section 7.

1.4 Gas-ballast control

To pump high vapour loads, gas-ballast is delivered into the pump to prevent condensation of the vapour carried by the pumped gases.
Air can be introduced to the low vacuum stages through the gas-ballast valve (not fitted on 05 variant). Alternatively, an inert gas such as nitrogen can be supplied through a suitable external valve.
The gas-ballast control has three positions:
Closed (position ‘0’)Low flow (position ‘I’)High flow (position ‘II’)

1.5 Construction

The pump scrolls are made from anodised aluminium and the motor housing made from aluminium only. All surfaces of the pump which are exposed to the pumped gases are free from copper, zinc and cadmium.

2Technical data

2.1 Operating and storage conditions

Ambient temperature: Operating range 10 °C to 40 °C Storage range -30 °C to 70 °C Surface temperature of pump above ambient (when operating at ultimate) typically 45 °C Maximum humidity (operation) 90% Altitude up to 2000 m

2.2 Performance

2.2.1 General

General characteristics of the pumps are defined in Table 1 below. Characteristics shown are displacement, pumping speed and maximum permitted interface pressures.
Technical data
Suckback on pump switch off typically 30 mbar ls-1 (leak tightness 1x10-6 mbar ls-1).

Maximum pumping speed (m Pneurop 6602 (1979) 50 Hz electrical supply 60 Hz electrical supply
Maximum permitted inlet pressure and gas-ballast inlet pressure
Maximum permitted outlet pressure *
* The XDS pumps can survive an excursion to 1 bar gauge in the exhaust line. However, under normal
operating conditions (with the pump running) the exhaust line pressure should be as close as possible to atmospheric pressure. If the pump is operated with a raised exhaust line pressure this will accelerate tip seal wear and lead to a loss of pumping performance.
