• Description: The system supplier PIERBURG is the leading manufacturer of vacuum pumps. As an OEM, PIERBURG has decades of expertise in development and production and has made a significant contribution to the "state of the art" thanks to its innovative concepts. Even service – in the form of information about the product – has a long-standing tradition at PIERBURG.
  Vacuum is used in many vehicles for the brake boosters and for the actuation of pneumatic equipment. Vacuum pumps generate the vacuum required in supercharged or heavily de-throttled engines. Due to increasingly heavy de-throttling and the rising number of supercharged engines, more vacuum pumps are being fitted in vehicles today than ever before.
  Technical information
  - Vacuum pumps in motor vehicles generate a vacuum of approx. 0.7 to 0.9 bar. The model commonly used today is the single-vane vacuum pump. This model is characterized by a high level of efficiency and low power consumption. Vacuum pumps require lubricating oil for the interior sealing, heat dissipation, and lubrication. The lubricating oil is often supplied via channels in the cylinder head or in the camshaft. The lubricating oil is fed back into the engine together with the exhaust air. The oil supply and oil quality have a large influence on the wear. For this reason, insufficient oil supply is the most common cause of malfunctions on vacuum pumps. Aged or impure lubricating oil contains large amounts of contamination due to mechanical abrasion of the engine or soot particulates from the exhaust gas. This may cause the vacuum pump to wear prematurely or clog the oil channels. Vacuum pumps can wear out due to inadequate lubrication, age, and oil quality, and age in a similar way to the engine itself.
  Diagnostic information
  - In many vehicles, components are actuated or controlled using a vacuum. A faulty vacuum pump or malfunction in the vacuum system can therefore present itself in a number of ways. For example, when braking several times in quick succession the braking power may noticeably reduce or the brake pedal may become "hard". There may also be faults or error messages in the control unit for one or more systems or components that are controlled by vacuum. Black smoke, erratic engine running, lack of power, or engine misfires may also be caused due to a lack of vacuum.
  - Slack brake boosters can be quickly attributed to the vacuum pump. Error messages that occur sporadically and cannot be reproduced, or which are extremely difficult to reproduce, present a challenge for the diagnostic specialist.
  - The oil supply and oil quality have a large influence on the wear. For this reason, insufficient oil supply is the most common cause of malfunctions on vacuum pumps. Aged or impure lubricating oil contains large amounts of contamination due to mechanical abrasion of the engine or soot particulates from the exhaust gas. This may clog the oil channels or cause a vacuum pump to wear prematurely. Following repeated braking, for example, the required vacuum can then no longer be generated quickly enough, resulting in an error message in the control unit. These faults only occur sporadically and are difficult to reproduce. When replacing a vacuum pump, it is therefore always necessary to check the oil supply and drive of the vacuum pump. The vacuum pump can be checked using a vacuum hand pump. Since the vacuum hand pump does not have a significant volume, we recommend that the brake booster remain connected during the check. A brake booster has a relatively large volume, which can also be used to perform diagnostics on a worn vacuum pump.
