Vacuum Pumps
For safety and comfort
System supplier Pierburg is a leading OE manufacturer of vacuum pumps for the international automotive industry. As an OE manufacturer, Pierburg boasts decades of expertise in development and manufacturing, and its innovative designs have made significant contributions to the state of the art. Motorservice is a world-leading supplier of vacuum pumps in the aftermarket, and offers high availability and consistently first-class quality, even in the face of increasing market demand.
Vacuum pumps produce the required vacuum for the brake boosters, as well as for controlling the functions of the central locking system, air conditioning, automatic transmission unit, emission control systems and other control elements.
With the help of a vacuum, high adjusting forces can be generated in a small installation space. Vacuum pumps are installed in vehicles that do not have sufficient vacuum. Conventional diesel engines are fitted as standard with a vacuum pump, as they have no throttle valve, and cannot therefore generate any pressure difference. Vacuum pumps are also increasingly found in modern petrol engines, where there is insufficient vacuum in the intake manifold after the throttle valve.
Product range
Motorservice offers a comprehensive product range of mechanical vacuum pumps, tandem vacuum/oil or fuel/vacuum pumps and electric vacuum pumps. Over 190 articles cover more than 160 million passenger cars and light commercial vehicles.
Pierburg quality
Pierburg is a specialist in the fields of emission control, air supply and throttle valves. Decades of experience, an innovative approach and recognised expertise in all aspects of engines give Pierburg the ideal background to systematically develop and manufacture future-oriented components, modules and systems.
Mechanical vacuum pumps
are found in many vehicles
Mechanical vacuum pumps can be driven by means of cams, tappets, chains, belts, or cam discs. Pumps that move a piston or diaphragm back and forth and generate a vacuum are well established in the field.
A newer development is vane pumps with a rotary drive. Here, a rotor with one or more vanes forms compartments, the size of which varies during the work cycle.
Tandem pumps, vacuum/oil
Reliable lubrication
While the single-vane pump generates the vacuum required for the brake booster, the oil pump ensures an adequate oil supply. If the oil pump is located on the cylinder head, the connected G-rotor oil pump pumps excess oil from the cylinder head into the crankcase sump. Alternatively, these oil and vacuum pumps can also be installed in the crankcase sump to draw in the oil and supply the engine with sufficient oil for lubrication.
Your benefits at a glance:
- Pierburg is an OEM for oil and vacuum pumps.
- Motorservice is a leading supplier of oil and vacuum pumps in the aftermarket.
- High availability
Tandem pumps fuel/vacuum
for easy mounting
In "tandem pumps", vacuum pumps are combined with other supply pumps ona common axle. In the fuel/vacuum combination, they take on the functions of mechanical vacuum pumps and are also used for fuel feed.
Your benefits at a glance:
- Motorservice is a leading supplier of fuel and vacuum pumps in the aftermarket.
- High availability
- Replacement in line with current market value Item
Electric vacuum pumps
On demand, powerful, maintenance-free
Motorservice has added seven electric vacuum pumps from Pierburg to its product range. One reasons for developing electric vacuum pumps is to maintain brake boosting in downsized petrol engines.
They can be used to replace 45 OE pumps. This corresponds to a market potential of almost 32 million vehicles in all common makes of vehicle.
The high compatibility is achieved by omitting vehicle-specific holders: Only the actual vacuum pump is replaced.
Your benefits at a glance:
- Full brake boosters whenever needed
- Can be switched off, i.e. on demand
- This saves fuel and reduces emissions in comparison to mechanical vacuum pumps
- Powerful
- Maintenance-free
- Robust design
- Superb decoupling due to rubber bearings, i.e. lower structure-borne noise and therefore very quiet
- Enables advanced start-stop coasting
- Also suitable for hybrid and fully electric vehicles
