3 You must use theXDS pump as specified in this Manual . Read thismanual before you install, operate and maintain theXDS pump. Important safety information is highlighted asWARNING and CAUTION instructions; you mustobey these instructions. The use of WARNINGSand CAUTIONS is defined this Manual , page, figure and tablenumbers are units used throughout this Manual conform tothe SI international system of units of are stated as absolute pressuresthroughout this Manual , unless otherwise following IEC warning labels appear on thepump:Warning - refer to - risk of electric are given where failure to observe the instruction could result in injury or death to are given where failure to observe the instruction could result in damage to the equipment, associated equipment and - hot directive implications This equipment is designed to meet therequirements of Group II Category 3equipment in accordance with Directive 94/9/EC of the European Parliament and theCouncil of 23rd March 1994 on theapproximation of the laws of the MemberStates concerning equipment and protectivesystems intended for use in potentiallyexplosive atmospheres.

4 (The ATEX Directive)The ATEX Category 3 applies in respect ofpotential ignition sources internal to theequipment. An ATEX Category has not beenassigned in respect of potential ignitionsources on the outside of the equipment asthe equipment has not been designed for usewhere there is an external potentiallyexplosive is no potential source of ignition withinthe pump during normal operation but theremay be potential sources of ignition underconditions of predicted and rare malfunctionas defined in the Directive. Accordingly,although the pump is designed to pumpflammable materials and mixtures, operatingprocedures should ensure that under allnormal and reasonably predicted conditions,these materials and mixtures are not withinexplosive limits.

5 Category 3 is consideredappropriate for the avoidance of ignition in thecase of a rare malfunction which allowsflammable materials or mixtures to passthrough the pump while within their JMay 07 XDS Dry PumpINTRODUCTION2 PAGE2 Figure 1 - The single-phase XDS dry pump1.

6 Refer toFigure 1 for item numbers in brackets in thefollowing XDS pump is a compact, reliable Vacuum pumpwhich is suitable for use on vapour handlingprocesses. The XDS pump may be used for somepumping applications involving corrosive substancesand particulates; for information on pumpingflammable gases, please refer to Section andcontact BOC Edwards for any further body of the pump includes a fixed Scroll and anorbiting Scroll . The orbiting Scroll is driven by theelectric motor through an eccentric cam on themotor drive shaft. The movement of the orbitingscroll, meshed with the fixed Scroll , formssuccessive crescent shaped volumes in the which enters the pump through the inlet iscompressed by the movement of the orbiting scrolland swept towards the centre of the fixed compressed gas enters the exhaust port nearthe centre of the stationary Scroll and is exhaustedfrom the pump through the XDS pump is a dry Vacuum pump, as all thebearings, with their hydrocarbon lubricant, areisolated from the Vacuum inlet of the pump is fitted with a removable inletstrainer which prevents the entry of debris into pump mechanism is driven directly by a single-phase or three-phase electric motor.

7 Single-phasemotors are fitted with an on/off switch (7) and athermal overload device. When the motor is toohot, the thermal overload device switches off thepump. The thermal overload device has anautomatic reset; when the motor cools down, thedevice resets and (unless you have incorporatedsuitable control equipment which must be manuallyreset), the motor will restart. The pump is air-cooled by a fan mounted at theopposite end to the pump is mounted on a baseplate on rubber of suitable vibration isolators and otheraccessories are provided in Section controlTo pump high vapour loads, gas-ballast is deliveredinto the pump to prevent condensation of thevapour carried by the pumped can be introduced to the low Vacuum stagesthrough the gas-ballast valve.

All surfaces of the pump which areexposed to the pumped gases are free from copper,zinc and JMay 07 XDS Dry Product classificationType of protection against Class 1electric shockSupply connection110-120 V, 50/60 Hz or 220-240 V, 50/60 HzMode of operation:ContinuousProtection against Not protectedhazards of explosionProtection against Not protectedingress of liquids(IPXO)Installation categoryIIPollution degree2 Degree of mobilityPortable(benchmounted)May 07 Issue JXDS Dry PumpTECHNICAL DATA5 PAGE52 TECHNICAL and storage conditionsAmbient temperature.
