ZF TRW’s fixed displacement pumps for transmission gearbox actuation and cooling have been enhanced to achieve maximum pump efficiency, leading to reduced CO2 emissions to meet the demand for Green solutions. At the same time, TRW’s outer gear pumps deliver superior startup performance even at -40ºC, a significant advantage compared to other designs. NVH performance is world class given TRW’s years of experience with steering pumps. Contamination worries are minimized as TRW has the processes and capabilities to provide parts according to the strictest OEM cleanliness standards.
ZF TRW’s pump engineering team has broad product and program experience which mitigates launch risk and shortens the time to market.
