Operating Instructions and follow the information so as to ensure optimum and safe working right from the start. The Leybold TRIVAC B has been designed for safe and efficient operation when used properly and in accordance with these Operating Instructions.
Page 5
Do not operate the pump with any of the covers removed. Serious injury may result. The location at which the TRIVAC B (including its accessories) is being operated should be such that angles over 10° from the vertical are avoided. Select the operating place so that all controls are easily accessible.
Page 6
The pump is not suited for oxygen operation. DANGER Before commissioning the TRIVAC B, make sure that the media which are to be pumped are compatible with each other so as to avoid hazardous situations. All relevant safety standards and regulations must be observed.
Page 7
Please take note of the marking on the type plates and any additional information on the pump. The standard version of the TRIVAC B is not suited for operation in explosion hazard areas. The TRIVAC pumps including the accessories are fundamentally not suited for pumping of combustible and explosive gases or vapours.
Page 8
Before pumping vapours the TRIVAC B should have attained its operating temperature. This will be the case approximately 30 minutes after having started the pump. During this warming up phase, the pump should be separated from the process, by a blocking valve in the intake line, for example.

ATEX TRIVAC B ATEX Categories 3 i and 3 i/o Vacuum Pump Operating Instructions for Operation in Explosion Hazard Areas The vacuum pumps are designed and constructed in such a way that the occurrence of foreseeable ignition sources during normal operation can be excluded.

Higher maximum surface temperatures can occur when filling and opera- NOTICE ting the pump with types of oil which differ from the Leybold oil LVO 100. This is due to the frequently worse lubrication and cooling properties of such oil.

Wipe plastic parts on the pumps of category 3G outside only with a moistened piece of cloth. Only original Leybold oil filters and gas inlet filters must be used since these have been designed such that proper connection to ground is ensured.

Fig. 1 TRIVAC B pump with accessories Description TRIVAC B pumps are oil-sealed rotary vane pumps. The TRIVAC D 4 B and D 8 B are dual-stage pumps. The number in the type designation (16 or 25) indicates the pumping speed in m ·...

(2/10). The oil entrained in the gas is coarsely trapped in the inter- nal demister (2/11); there the oil is also freed of mechanical impurities. The TRIVAC B pumps do not have an internal demister. The gas leaves the TRIVAC B through the exhaust port.
Page 16
The oil suction line is placed low, resulting in a large usable oil reser- voir. The oil is separated from the gas in the TRIVAC B in two steps as described above. First, small droplets are coalesced into large drops in the internal demister (2/11) fitted above the exhaust valve (2/10).

- Part 17“. Pay attention to the safety information 0.5. The TRIVAC B pump can be set up on a flat, horizontal surface. Rubber feet under the coupling housing ensure that the pump can not slip. If you wish firmly install the pump in place, insert bolts through bore holes in the rubber feet.

The maximum exhaust pressure must not exceed 0.5 bar (g). Conforming Utilization TRIVAC B pumps can pump gases and vapours, and evacuate vessels or vacuum systems in the fine vacuum range. They have been designed particu- larly for use in connection with corrosive or aggressive media.
Page 27
Installation 3.2.1 Non-conforming Utilization The TRIVAC B is not suited for pumping of: CAUTION radioactive and toxic substances pyrophorous substances corrosive gases oxygen (or other highly reactive gases) at concentrations exceeding that of the atmosphere (>21 % for oxygen). The pumps are not suited for pumping of liquids or media which carry NOTICE large quantities of dust.
Page 29
Installation Connection to the System Before connecting the TRIVAC B, remove the shipping seals from the con- nection flanges (7/2) and (7/3). Retain the shipping seals in case you need to store the pump in the future. The pump is shipped with intake and exhaust flanges mounted for horizon- tal connection of the connecting lines.
Page 30
In order to reduce the emission of oil vapours we recommend the installation of an additional exhaust filter (Leybold accessory, see Section 1.5). Depending on the type of appli- cation or the kind of pumped media, the corresponding regulations and information sheets must be observed.
Page 31
3.4.2 Pump with Three-Phase AC Motor TRIVAC B pumps with a three-phase motor are supplied without accessories for electrical connection. They must be connected via the appropriate cable, and a suitable motor protection switch.
Page 33
Operation Operation Media Compatibility TRIVAC B pumps can pump condensable gases and vapours, provided that the gas ballast valve is open and the pump has attained its operating temperature. Start-up NOTICE Each time before starting up check the oil level. The pump must never be operated with an oil level below the minimum.
Page 34
4.3.2 Pumping of Condensable Gases and Vapours With the gas ballast valve open (position I) and at operating temperature, TRIVAC B pumps can pump pure water vapour up to the water vapour tole- rance specified by the technical data. If the vapour pressure increases above the permissible level, the water vapour will condense in the oil of the pump.

TRIVAC B pumps. Further details are available from Leybold on request. If the TRIVAC B is used in ambient air which is much contaminated, make NOTICE sure that the air circulation and the gas ballast valve are not adversely affected.
Page 39
Maintenance Leybold Service Whenever you send a pump to Leybold, indicate whether the pump is con- taminated or is free of substances which could pose a health hazard. If it is contaminated, specify exactly which substances are involved. You must use the form we have prepared for this purpose.
Page 40
Maintenance Monitoring the Oil Level During operation of the TRIVAC B the oil level must always remain between marks (9/2) and (9/3) on the oil-level glass. The amount of oil must be che- cked and topped up as required. Check and top up oil only after having shut down the pump first.
Page 46
Bushing (12/12) For material No., see spare parts list The TRIVAC B has one shaft seal. Oil marks under the coupling housing are signs of a damaged shaft seal. The shaft seal can be replaced without removing or disassembling the pump module.

Waste oil from vacuum pumps must not be mixed with other substances or materials. Waste oil from vacuum pumps (Leybold oils which are based on mineral oils) which are subject to normal wear and which are contaminated due to the influence of oxygen in the air, high temperatures or mechanical wear must be disposed of through the locally available waste oil disposal system.
