WARNING

1Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards E2M28 and E2M30 rotary vacuum 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 that must be followed. 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

 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 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 flammable materials or mixtures to pass through the pump while within their explosive limits.

 When flammable or pyrophoric materials are present within the equipment:

 Do 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 of the nearest Edwards company.

Introduction

1.3 Description

The Edwards E2M28 and E2M30 pumps are shown in Figure 1. Refer to Figure 1 for item numbers in brackets in the following descriptions.

The E2M28 and E2M30 pumps are two-stage, direct drive, sliding vane pumps. 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 flexible coupling by a single-phase or three-phase (four pole) motor.

The motors are totally enclosed and are cooled by the motor-cooling fan which 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 device 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.

The level and condition of oil in the oil box reservoir can be inspected through the oil sight-glass (12). An oil fillerplug (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 accessories are given in Section 7.5.

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 which can be adjusted, as required, between closed and fully open.

2.5 Electrical data

Refer to Table 5 and 6. For motor current information please refer to the motor rating plate. The motor start-up current is drawn for less than one second, so 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 the pump is used 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.

WARNING

3.1 Safety

If a hydrocarbon oil is used in thi s pump, do not use the pump to process oxyg en in concentration s greater than 25% in volume. If the oxygen concentration is greater than 25%, there is a risk of fire or explosion in the oil-box of the pump.

Do not use the E2M28 or E2M30 pump to pump hazardous substances.

Obey the safety instructions listed below and take note of appropriate precautions. If not, injury to people and damage to equipment can result.

A373-10-880 Issue T

Installation

Prevent any part of the human body from coming into contact with the vacuum.

 A suitably trained and supervised technician must install the pump.

 Wear the appropriate safety-clothing when coming into contact with contaminated components.

 Vent and purge the vacuum system before starting installation work.

 Ensure that the installation technician is familiar with the safety procedures that relate to the pump-oil and

the products processed by the pumping system. Take suitable precautions to avoid the inhalation of oil mist and excessive skin contact with pump oil, as prolonged exposure can be harmful.

 Disconnect the other components in the pumping system from the electrical supply so that they cannot be

operated accidentally.

 Safely route any electrical supply cables so that they cannot accidentally trip people.

 Ensure that the E2M28 or E2M30 pump is suitable for the application. If there is any doubt as to the

suitability of the pump for the application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (refer to the Associated Publication at the end of the contents list at the front of this manual).

3.2 System design

Consider the following points when designing the pumping system:

 Use a suitable inlet-valve to isolate the pump from the vacuum system to allow the pump to warm up before

pumping condensable vapours, or to maintain vacuum when the pump is switched off.

 Avoid high levels of heat input to the pump from the process gases, otherwise the pump may overheat and

seize, and cause the motor thermal overload device to open.

 If the pump is used in a high ambient temperature and has a high gas throughput, the temperature of the

pump-body may exceed 70°C. Fit suitable guards to prevent contact with hot surfaces.

 Make sure that the exhaust pipeline cannot become blocked. If an outlet-isolation valve is fitted, make sure

the pump cannot be operated with the valve closed.
