Single-Vane Vacuum Pumps

Single-Vane Vacuum Pumps

Product catalog summary

Introduction
The document discusses the mechanical single-vane vacuum pumps used in passenger cars and light-duty trucks to enhance braking reliability and manage various engine functions. These pumps are crucial for diesel and gasoline engines, particularly those with direct injection, as they supply vacuum to brake boosters, servo valves, and control systems like exhaust gas recirculation and turbochargers.

Design and Features
The single-vane vacuum pump is designed with a rotary drive, offering reduced production costs due to fewer components. It can be equipped with a secondary vacuum port for additional devices and is available as a tandem pump with an oil pump. The pump requires lube oil for sealing, heat dissipation, and lubrication, with the exhausted air and oil returned to the engine. It is modular, available in various sizes, and can be adapted to different engine configurations.

Model Series

N2 Series: Features a vane rotating in an elliptical path with pivoted slide shoes, ensuring low wear and power consumption. It is suitable for extreme temperatures.
N3 Series: Utilizes advanced engineering plastics for reduced mass and friction, offering low power consumption and smooth operation. It is cost-efficient due to its deep-drawn steel body.
EVO Series: Based on N3 technology, it includes an aluminum flange housing for enhanced efficiency and power consumption. It is noted for its top market characteristics.

Performance and Efficiency
The pumps are designed for high-speed applications, contributing to fuel savings due to low power consumption. They can be driven by the camshaft or a secondary shaft, with a coupling to accommodate assembly offsets. The pumps are environmentally friendly, using recyclable materials.

Benefits
The single-vane vacuum pumps offer reliable performance, low power consumption, long service life, and applicability at high temperatures. They are lightweight, cost-effective, and adaptable to customer-specific requirements, with options for separate vacuum ports.

Conclusion
Pierburg Pump Technology provides a range of single-vane vacuum pumps that meet various customer specifications, ensuring efficient and reliable operation in automotive applications.

Mechanical single-vane vacuum pump Pneumatically acting brake boosters are installed in passenger cars and light-duty trucks to increase braking reliability and ease of handling. For diesel engines and increasingly also for gasoline engines, specifically those with direct injection, vacuum pumps are used for supplying brake boosters and servo valves with vacuum, for controlling exhaust gas re- circulation systems and turbo chargers, for example. Based on longstanding experience with pistons, membrane and swinging-vane vacuum pumps a single-vane vacuum pump was developed in line with optimization...

be fitted with a secondary vacuum port for servo devices. Moreover, the single-vane vacuum pump is also available in combination with an oil pump as a so-called tandem pump. mum flexibility is ensured for accommodating the system on the engine. All presently known vacuum conditions specified by the various customers can be met with the single-vane vacuum pump model range available. The rotor with integrated shaft is arranged overhung in the customer-specific pump flange. The single-vane vacuum pump needs lube oil for sealing the internal gaps, for heat dissipation and for lubricating the sliding...

efficient buildup of the lubricating film, contributing to extremely low wearing rates and reduced power consumption. Thanks to the selective use of steel components the N2 series is applicable even at extreme temperatures which may prevail, for example, in the direct surrounds of the exhaust system. make for extremely low power consumption. In addition, an extraordinarily smooth run thanks to minimized rotational imbalances at the driving shaft contributes to the high quality standard of this series. The choice of a deep-drawn steel body ensures excellent cost efficiency. EVO series N3 series...

Paying tribute to increased rev demands, e.g. for tandem pumps, high-speed resistant applications are developed. The low power consumption achieved with the diverse installation sizes and technologies contributes to fuel savings. All series can be driven via the camshaft or a secondary shaft. The connecting element is a coupling designed to compensate for offsets due to the assembly or to tolerances. Oil is supplied from the engine’s oil circuit. Single-vane vacuum pumps are delivered ready for installation, with customer-specific intake connections and integrated check valve as well as a sealing...
