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 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 of your nearest Edwards company,Page 2 Edwards Limited 2012 All rights reserved.

A373 10 880 Issue R,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, 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 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 you can adjust as required between closed and fully open.

A373 10 880 Issue R,Technical data,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 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.

A373 10 880 Issue R,Installation,3 Installation,3 1 Safety. If you use a hydrocarbon oil in this pump you must not use the pump to process oxygen in. concentrations greater than 25 in volume If you do there is a risk of fire or explosion in the. oil box of the pump, You must not use the E2M28 or E2M30 pump to pump hazardous substances.
Obey the safety instructions listed below and take note of appropriate precautions If you do not. you can cause injury to people and damage to equipment. A suitably trained and supervised technician must install the pump. Wear the appropriate safety clothing when you come into contact with contaminated components. Vent and purge your vacuum system before you start installation work. Ensure that the installation technician is familiar with the safety procedures which 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. You must ensure that the E2M28 or E2M30 pump is suitable for your application If you have any doubts as to. the suitability of the pump for your 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. 3 2 System design, Consider the following points when you design your pumping system. Use a suitable inlet valve to isolate the pump from your vacuum system if you need to allow the pump to. warm up before you pump condensable vapours or if you need 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 you use the pump in a high ambient temperature and have a high gas throughput the temperature of the. pump body may exceed 70 C and you must fit suitable guards to prevent contact with hot surfaces. Make sure that the exhaust pipeline cannot become blocked If you have an outlet isolation valve make sure. that you cannot operate the pump with the valve closed.
