Hella 358157041 UP30 Electric Vacuum Pump for Brake Booster Systems

The Hella 358157041 is an electric vacuum pump (UP30) engineered to support or independently generate vacuum pressure for pneumatic brake booster systems. Operating on the rotary vane compression principle, this pump delivers reliable, on-demand vacuum independent of engine type or operating conditions — making it an ideal solution for hybrid, electric, fuel cell, and downsized engine applications.

Key Features:

• Stand-alone vacuum capability: Can serve as the sole vacuum source for the brake booster and auxiliary consumers, without relying on intake manifold vacuum from an internal combustion engine
• Rotary vane compressor design: Features an eccentric rotor within the pump chamber; sliding vanes continuously compress the enclosed volume to generate stable vacuum
• Broad engine compatibility: Engineered for use with conventional internal combustion engines, hybrid drives, electric motors, and fuel cell vehicles
• Dry-running operation: Requires no lubrication fluid, reducing maintenance needs and supporting flexible mounting configurations both on and off the engine
• 12V electric operation: Electrically controlled and activated on demand, with a 2-pin connector for integration with the vehicle's ECU or relay box
• Maintenance-free construction: Built for long-term, trouble-free service life in demanding under-hood environments
• OE-quality engineering: Manufactured by Hella, a globally recognized OE supplier of electric vacuum pumps
