Provide an adequate ground connection for the pump so as to avoid any electrostatic charging. GA01208_002_C1 - 07/2018 - © Leybold... -
Page 6: Thermal Hazards
Regarding the suitability of the TRIVAC pumps for special applications in which such gases, respec- tively substances shall be pumped, Leybold should be consulted first. If the pump has previously handled hazardous gases, implement the proper precautionary measures before opening the intake or exhaust connection. -

Here, the exhaust line must slope down and away from the pump. In the case of custom pumps please note the information provided in the supplementary sheets. GA01208_002_C1 - 07/2018 - © Leybold... -
Page 9: Description
The pump module consists of assembly parts which are pin-fitted so as to allow easy disassembly and reassembly. The pump module can be easily removed without special tools. TRIVAC-B-DOT pumps are equipped with special seals capable of NOTICE resisting brake fluids. GA01208_002_C1 - 07/2018 - © Leybold... -
Page 10: Function
The gas ballast stops condensation of vapours in the pump chamber up to the limit of the water vapour tolerance as specified in the technical data for the pump. GA01208_002_C1 - 07/2018 - © Leybold... - Page 11 (4/6) against its seat.This effectively prevents backstreaming of oil or oil vapours. The anti-suckback valve (2/3) operates independently of the operating mode of the pump, i.e. also with gas ballast. GA01208_002_C1 - 07/2018 - © Leybold...

Page 12: Lubricants / Gaskets
These pumps must only be operated with brake fluids in accordance with DOT-3 and DOT-4 or alternative operating agents which have been approved by Leybold. TRIVAC-B-DOT pumps and accessories are equipped with special seals which are capable of resisting exposure to brake fluids. GA01208_002_C1 - 07/2018 - © Leybold... -

When connecting or removing the pump, do not move under hoisted loads. -
Page 18: Installation
Maximum heat dissipation corresponds approximately to the installed motor power. When failing, capacitors may heat up excessively and generate smoke. Therefore the pump must be placed with a sufficient clearance from inflammable or combustible material. There exists the risk of fire! GA01208_002_C1 - 07/2018 - © Leybold... -
Page 19: Conforming Utilization
Corresponding protection devices need to be provided. The TRIVAC-B-DOT is not suited for pumping of: n combustible and explosive gases or vapours n Oxidant n pyrophorous substances. Our technical sales department is available for further advice in these matters. GA01208_002_C1 - 07/2018 - © Leybold... -
Page 20: Connection To The System
The intake line must be clean. Deposits in the intake line may outgas and adversely affect the vacuum. The connecting flanges must be clean and undamaged. The maximum throughput of the pump is equivalent to the pumping speed of the pump. GA01208_002_C1 - 07/2018 - © Leybold... - Page 21 In order to reduce the emission of oil vapours we recommend the installation of an additional exhaust fil- ter (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.

(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. GA01208_002_C1 - 07/2018 - © Leybold... -
Page 26: Operating Temperature
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 27: Shutdown Through Monitoring Components
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 GA01208_002_C1 - 07/2018 - © Leybold... -

Page 31: Monitoring The Oil Level
Check and top up oil only after having shut down the pump first. Please note the safety information given in Section 0.3 und 0.4. Pumps which have not directly been delivered from Leybold, e.g. in sys tems, may have been filled with oils different from DOT-4. In this case a refill with DOT-4 may cause problems. -
Page 32: Oil Change
When disposing of waste oil, observe the applicable environment protection regulations! When changing the oil use the same type of oil which was previously in the pump. If you want to change the type of oil entirely please consult us first. GA01208_002_C1 - 07/2018 - © Leybold... - Page 33 When an exhaust filter with lubricant return has been installed on the pump please also exchange the oil there. We can only guarantee that the pump operates as specified by the NOTICE technical data if the lubricants recommended by us are used. GA01208_002_C1 - 07/2018 - © Leybold...

Page 42: Troubleshooting
1) 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. GA01208_002_C1 - 07/2018 - © Leybold... - Page 43 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.
