1Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards E2M0.7, and E2M1.5 rotary vacuum pumps. You must use the pump as specified in this manual. Read this manual before you install and ope rate 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 sys tem of units of measurement. Equivalent values using imperial units of measurement are also included.

The following warning symbols are 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 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 potential 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 pr ocedures should ensure that under all normal and reasonably predictable conditions, these materia ls 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 while within their explosive limits.

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

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

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

Introduction

1.3 Description

The Edwards E2M0.7 and E2M1.5 pump is shown in Figure 1. Refer to Figure 1 for item numbers in brackets in the following descriptions.

The E2M0.7 and E2M1.5 pumps are two-stage, direct drive, sli ding vane pumps . The pump is oil-sealed and designed for reliable, long-term operation. The pump is a free-standing unit. The drive is provided through a coupling by a single-phase motor.

The motor is totally enclosed and is cooled by the motor-cooling fan which directs air along the motor fins. The motors are fitted with 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 the motor will restart.

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 oil suckback unless the gas-ballast valve is open. For protection in this case, refer to Section 1.4.

The level and condition of the oil in the oil box reservoir can be inspected through the sight-glass (9). An oil fillerplug (6) is fitted to the top of the oil box. An oil drain-plug (11) is fitted at the bottom of the oil box.

The pump has a carrying handle (3), inlet-port (4), outlet nozzle (7) and gas-ballast control (5). The pump is mounted on a steel baseplate (12) on rubber pads. Details of suitable vibration is olators and other reco mmende d acce ssories are given in Section 7.4.

1.4 Gas-ballast

To pump high vapour loads, gas-ballast is delivered into the pump to prevent condensation of the vapour carried by the pumped gases.

Air (or another gas) can be introduced into the low vacuum stage through the gas-ballast control. The gas-ballast control is a multi-turn valve that can be adjusted, as required, between closed and fully open.
