Page 8: Classification And Marking Of The Pump
1 Equipment-category 1 applies to all devices for use in areas in which explosive atmospheres caused by mixtures of air and gases, vapours, mists or air/dusts mixtures are highly likely to occur and are present continuously, for long periods of time or frequently. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 9: Hazards Caused By Noise
Operating Instructions apply. Note the markings of the attached electrical apparatus, too. Hazards caused by noise CAUTION The noise level produced by the pump less than 60 dB(A). Suitable hearing protection measures must be introduced. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 10: Risk Of Damaging The Pump
Corrosion, deposits and cracking of oil within the pump are not allowed. Normal amounts of humidity within the range of the pump’s water vapour tolerance will not significantly affect pump performance when the gas ballast is active. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 11: Description
The oil injected into the pump chamber is used for sealing and lubricating. The pinking in the pump which usually occurs when attaining the ultimate pressure is prevented by admitting a very small amount of air into the pump chamber. GA01212_002_C1 - 04/2017 - © Leybold... - Page 12 To enable the TRIVAC D 16 B Ex to be used at intake pressures as high as Lube system 1,000 mbar, a special lubricating system was developed featuring force-lubri- cation of the sliding bearings.

Page 21: Transport And Storage
When a pump is put into operation after it has been shelved for over one year, standard maintenance should be run on the pump and the oil should also be exchanged (see Section 5.4). We recommend that you contact the Leybold Service. GA01212_002_C1 - 04/2017 - © Leybold... -

Max. tilt for the pump is 10° from the vertical. The site chosen should allow adequate air circulation to cool the NOTICE TRIVAC D 16 B Ex (keep front and rear unobstructed). The oil-level glass must be visible. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 23: Conforming Utilization
The utilization of the pump must be verified by the operating company against corresponding equipment-categories, temperature classifications and gas groups as specified in the explosion protection document drawn up. Our technical sales department is available for further advice in these mat- ters. GA01212_002_C1 - 04/2017 - © Leybold... -

Page 26: Connecting To The System
The intake line must be clean and free of welding beads and scales. Deposits in the intake line may outgas and adversely affect the vacuum. The connect- ing flanges must be clean and undamaged. Use suitable intake filters, respectively suitable accessories on the pump GA01212_002_C1 - 04/2017 - © Leybold... - Page 27 In inlet pressure for the gas ballast should be about 1013 mbar (absolute) and sufficient quantities of gas must be available (about 1/10 of the pumping speed).

(if possible via a valve). Once all vapours have been pumped off from a process (e.g. during drying), the gas ballast valve can be closed to improve the attainable ultimate pressure. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 34: Operating Temperatures
Observe Safety Information 0.3. If – due to the ambient conditions – this temperature range is exceeded at either end of the range, contact Leybold Sales. The motor may accelerate with a delay when simultaneously an undervoltage is present at the motor and the pump is at the minimum permissible and ambient temperature. -
Page 35: Shutdown Through Monitoring Facilities
In order to prevent the pump from running up unexpectedly after a mains power failure, the pump must be integrated in the control system in such a way that the pump can only be switched on again manually. This applies equally to emergency cut-out arrangements. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 36: Maintenance
When the TRIVAC D 16 B Ex has been pumping corrosive media we rec- ommend that possibly planned maintenance work be carried out immedi- ately in order to prevent corrosion of the pump while it is at standstill. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 37: Maintenance Plan
It is required to service the pump every two years covering the following: Cleaning ■ Checking all individual components ■ Exchange of all seals and gaskets ■ Functional check. ■ This service must only be run by the Leybold Service. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 38: Leybold Service
For safety reasons, every TRIVAC D 16 B Ex must be subjected every two years or in the case of a failure, to a revision at Leybold. During the check every two years also all seals and filters of the pump are replaced. -
Page 39: Monitoring The Oil Level
If you want to check the oil, switch off the pump first and drain out from the warm pump the required amount of oil through the oil drain (9/4) into a beak- er or similar. Please note the safety information given in Section 5.4. GA01212_002_C1 - 04/2017 - © Leybold... -
Page 40: Oil Change
2,000 – 3,000 operating hours or after one year. At high intake pressures and intake temperatures and/or when pumping contaminated gases, the oil will have to be changed much more frequently. Further oil changes should be made before and after long-term storage of the pump. GA01212_002_C1 - 04/2017 - © Leybold... - Page 41 The tightening torque for the bolts (9/1) and (9/4) has been specified at 10 Nm. We can only guarantee that the pump operates as specified by the techni- NOTICE cal data if the lubricants recommended by us are used. GA01212_002_C1 - 04/2017 - © Leybold...

Bubble test: The warm pump with degassed oil is running without gas ballast and the intake is blanked off. The exhaust line is led into a vessel with water. If an evenly spaced line of bubbles appears then the pump has an external leak. GA01212_002_C1 - 04/2017 - © Leybold... - Page 47 Intake pressure is too high. Lower the intake pressure. Internal demister is clogged. Clean or replace demister. Service Coupling element is worn. Install new coupling element. Vanes or bearings are damaged. Repair pump.
