Electric vacuum pump YJ30

Electric Vacuum Pumps in Brake Systems are very necessary for both electric and hybrid vehicles.

The brake system is one of the most important systems in any vehicle. Ensuring that stable and effective braking power is available at all times usually requires a vacuum pump.

Until recently, the majority of brake boosters used the vacuum generated by the internal combustion engine’s intake section. Under certain operating conditions (e.g. during the cold start/warm-up phase, driving at extreme altitudes or when using the air-conditioning system), the vacuum produced by the engine is no longer sufficient.

Electric vacuum pumps are used to ensure the reliable operation of the brake booster.

Aside from the internal combustion engine, modern engine technologies such as those found in electric or hybrid vehicles are not able to build up vacuum pressure.

The electric vacuum pump is therefore required to generate an alternative or additional vacuum for these technologies.

This additional vacuum pump ensures compliance with the latest safety standards, while maintaining reliable operation of the brake system, which operates with pneumatic brake boost.

Advantages of an additional vacuum pump

Supports all engine types, including hybrid and electric vehicles

Reduction in energy requirements thanks to on-demand pump operation

Supports the reduction of CO2 emissions

Independent of combustion engine technology

Maintenance-free (dry running, self-lubrication requires no connection to the oil circuit)

Electrically driven vacuum pumps support a flexible vehicle platform concept.
