Hella 34-33-2-283-333 Electric Vacuum Pump for Brake Booster

The Hella 34-33-2-283-333 (also known as Hella 009383101) is an electric vacuum pump designed to provide reliable vacuum pressure for brake booster systems. This OE-quality component ensures consistent and effective braking power, particularly in vehicles with modern engine technologies where natural engine vacuum may be insufficient.

Key Features:

• 12-volt electric operation for reliable performance
• 2-pin electrical connector with 180mm cable length
• Rotary vane compressor design for efficient vacuum generation
• Supplied without mounting bracket (holder)
• Engineered for quiet operation and low noise levels
• Durable construction meeting or exceeding OEM standards
• Direct replacement for BMW OEM part number 34332283333

This electric vacuum pump is essential for maintaining optimal brake booster function in vehicles where engine-generated vacuum is inadequate, such as during cold starts, at high altitudes, or in hybrid and performance applications. The pump operates based on the rotary vane compressor principle, using an off-center rotor with sliding blades to continuously compress air and generate the necessary vacuum pressure for safe, consistent braking performance.
