Electrically Powered Hydraulic Steering Pump for hybrid and electric vehicles

ZF’s EPHS Electrically Powered Hydraulic Steering Pump allows flexibility in vehicle design. EPHS can be used within current vehicle architecture to provide hydraulic power steering in vehicles with hybrid and engine off operations or full electric powertrains.


  • Energy and temperature savings
  • Low GHG emission due to engine decoupling of steering accessory. No parasitic loads
  • Engine off operation with full steering capability
  • Additional benefits when paired with ReAX to reduce pump flow during low steering demand (“Eco-cruise”)
  • Flow tunable to meet steering gear requirements
