Brake Systems Get Electric Vacuum Pump from HELLA

In order to take the functionality and performance of brake systems to new heights, HELLA has recently developed an electrically driven vacuum pump that promises outstanding performance, packaging, power efficiency, and durability.

High-efficiency diesel engines, gasoline, and turbo- and super-charged engines, as well as full electric or hybrid powertrains, are examples of where the company’s new electric vacuum pump is designed to offer on-demand brake-system vacuum.

Automotive manufacturers and suppliers are working to cut CO2 emissions to meet stringent new requirements taking effect in 2020 and 2025. Often, new fuel-saving approaches have a direct impact on other engine functions that, for instance, give vacuum to support brake-booster systems. HELLA’s all-new UP5.0 Electric Vacuum Pump effectively solves this problem by meeting vacuum requirements for brake boosters under the most demanding applications.

Beginning last year, OEMs faced penalties for CO2 emissions above 180g CO2/km. Reports say that in 2020, the limit will fall to 143g CO2/km, and by 2025 the limit will be 110g CO2/km.

Fully-independent vacuum generation and fuel efficiency were targets for the development of the UP5.0. The new vacuum pump is designed to help automakers meet new emissions marks, while satisfying customer demand for smooth and continuous brake-pedal feel with reliable performance.

As a bonus, the new electric vacuum pump will boost a vehicle’s fuel efficiency, leading to CO2 savings of up to 2g CO2/km compared to mechanical pumps. This is equal to fuel savings of 0.2 to 0.4 miles per gallon.

Through creative material selection, enhanced high-volume processes, and proprietary design, HELLA’s latest pump delivers cost savings of around 20 percent compared to the company’s previous generation of stand-alone vacuum pumps.

As a market leader, HELLA currently provides electric vacuum pumps to over 40 international OEMs. The company’s fuel-pump production capacity presently totals over six million units per year, and it has increased capacity in the mid-term. It produces fuel pumps in Romania, Germany, China, Mexico and the USA.
