Hella Electric Brake Booster Vacuum Pump

The Hella Electric Brake Booster Vacuum Pump line (also called an electric vacuum pump or auxiliary brake vacuum pump) supports or replaces engine-generated vacuum for a pneumatic power brake booster. Some engines can't supply enough manifold vacuum, and these pumps make up the difference. This can happen with diesel, hybrid and electric drivetrains, and with engines that have aggressive camshafts. It can also happen at high altitude or when the air conditioning is running.

Key Features:

• On-demand vacuum: The pump runs when the system needs it, which helps keep brake pedal feel and braking assist consistent.
• Support or stand-alone use: Depending on the model, the pump either adds to engine vacuum or serves as the only vacuum source for the brake booster and other vacuum consumers.
• Rotary vane design: An eccentric rotor with sliding vanes draws air out of the booster through the vacuum line.
• 12V electric operation: The pump is engine-independent, so it can work with conventional, hybrid and electric drive concepts.
• Proven OE technology: Hella has built electric vacuum pumps since 1999 and has produced more than 17 million of them.

These pumps are a dependable way to restore or improve brake booster performance. They suit OE-style replacement, engine swaps and custom builds. Choose the specific model for your application from the individual listings.
