Vacuum Pump Application and Function

The presented vacuum pump operates within the vacuum system of 1.6 HDi and 1.6 TDCi engines, responsible for generating constant vacuum for the brake booster, control valves, and other components requiring stable vacuum supply. Based on solutions used in PSA Group and Ford vehicles, this component ensures:

• adequate vacuum reserve under varying engine loads,
• smooth brake assist across the entire RPM range,
• seamless integration with the factory engine equipment.

As a product from the Vacuum Pumps category, this vacuum pump is crucial for braking safety and the correct operation of vacuum-controlled systems.

Compatibility and Part Number Selection

The pump is designed as an OEM part, meaning it fits factory mounting points, vacuum ports, and standard hoses used in 1.6 HDi and 1.6 TDCi engines. This facilitates plug-and-play installation without the need for modifications to the system or custom adapters.

For correct selection, it is recommended to verify compatibility using the OEM part number and available cross-reference numbers. This confirms compatibility with the specific engine version and vehicle year. This identification method minimizes the risk of purchasing an incorrect pump variant and speeds up the service process.

Performance Characteristics and Benefits

The offered vacuum pump, as an original part, maintains the operating parameters specified by the vehicle manufacturer. In practice, this means:

• stable vacuum available even at low engine speeds,
• consistent brake assist performance,
• proper interaction with control valves and vacuum actuators.

Thanks to its factory-designed housing and rotor, the pump maintains its seal and optimal efficiency, resulting in predictable vehicle behavior during braking and operation of auxiliary systems. This solution is particularly beneficial for users seeking performance close to the original factory fit.

Condition, Origin, and Economic Aspect

The product originates from the Peugeot line and is a used part, offering a sensible compromise between cost and maintaining factory operating parameters. Choosing an original, used vacuum pump allows for cost savings compared to new aftermarket replacements, while ensuring structural compatibility with the braking system and engine equipment.

This solution is particularly attractive for routine maintenance repairs where both safety and cost optimization are important, without compromising the predictable operation of the vacuum system.

Technical Support and Additional Materials

To better understand the relationship between the vacuum pump and other engine supply components, it is advisable to consult the material describing diagnostics and component selection by OEM and VIN numbers. The article Fuel System – Injectors, Pumps, and Fuel Tank: Maintenance and Repair thoroughly covers this, providing practical service tips and helpful part selection tables.
