1Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards E1M18 and E2M18 rotary vacuum pumps. You must use the pump as specified in this manual.

Read this manual before you install and operate the 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

The units used throughout this manual conform to the SI international system of units of measurement. The following warning labels are on the pump:

Warning - refer to accompanying documentation.

Warning - risk of electric shock.

Warning - hot surfaces.

Warning - do not block the pump outlet.

Introduction

1.2 ATEX directive implications

z This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with

Directive 94/9/EC of the European P arliament and the Council of 23rd March 1994 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 pote nt ial sources of ignition under conditions of predictable 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 predictable 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 flammabl e materials or mixtures to pass through the pump while within their explosive limits.

z When flammable or pyrophoric materials are present within the equipment you must:

z Not allow air to enter the equipment. z Ensure that the system is leak tight.

z For further information, please contact Edwards: refer to the Addresses page at the end of this manual for

details of your nearest Edwards company.

Introduction

Note: A pump with a single-phase motor is shown in this figure.

The motor shown in this figure is not representative of the motor used on the E1/E2M18 pumps with Item Numbers A343-17-984 and A363-17-984. On these pumps, items 7 and 9 are transposed, with Item 7 being an IEC60320 16-20 Amp socket.

Introduction

1.3 Description

The Edwards E1M18 and E2M18 pumps are shown in Figure 1. Refer to Figure 1 for item numbers in brackets in the following descriptions.

The E1M18 and E2M18 pumps are direct drive, sliding vane pumps. The E1M18 is a single-stage pump, and the E2M18 is a two-stage pump. The pump is oil-sealed and designed for reliable, long-term operation in both laboratory and industrial environments. The pump is a free-standing unit. The drive is provided through a fle xible coupling by a single-phase or three-phase (four pole) motor.

The motors are totally enclosed and are cooled by the motor-coo li ng fan wh ich directs air along the motor fins. The single-phase motors have 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 d evice resets and the motor will restart. The single phase motors have an on/off switch.

An oil pressure system lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents air suckback unless the gas-ballast valve is open. For protection in this case, refer to Section 1.4.

You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass (12). An oil filler-plug (1) is fitted to the top of the oil box. The pump has an oil drain-plug (11) to allow gravity oil drain.

The pump has an inlet-port (6), outlet nozzle (2) and gas-ballast control (3). The pump is mounted on two mild steel box section skids (10) on rubber pads. Details of suitable vibration isolators and other recommended accessori es are given in Section 7.4.

1.4 Gas-ballast

When you use the pump with high vapour throughputs, you should use the gas-ballast facility to prevent condensation of the vapours inside the pump. The con densates will contaminate the oil, will cause performance to deteri orate and may cause corrosion of the pump mechanism.

Air (or an inert gas) can be introduced into the pump mechanism through the gas-ballast control (Figure 1, item 3). The gas-ballast control is a multi-turn valve:

z From the closed position, the first two turns of the gas-ballast control provide an additional oil-feed to the

pump mechanism, but do not introduce gas-ballast into the pump. The additional oil-feed improves the lubrication and sealing of the pump mechanism.

z With further turns of the gas-ballast control, the gas-ballast flow into the pump increases from zero flow,

until the valve is fully open.

2.5 Electrical data

Refer to Table 5 and 6. The motor start-up current is drawn for less than one second, so you must use slow-blow fuses to prevent unnecessary fuse failure when the pump starts. Fuses should be to EN60269 Section 2.2. For conformance with CSA standards only CSA certified fuses are to be used. If you use the pump at temperatures lower than 13 °C, the start-up current will be drawn for longer; this may cause the motor thermal overload device to open.
