An earlier post on this forum on the same topic.

"Changing from a purely (engine driven pump) hydraulic to an electric driven pump will reduce the power demand by around 80% according to Reimpell , Stoll and Betzler in The Automotive Chassis , p286 in Edition 2.

Power requirements are around 80 amps at full demand , like parking lots for instance , but reduce to the 15 / 20 amps range for suburban driving.
Operating pressures are around 120 bar (1800 psi approx)

Many automotive suppliers (ZF , SKF etc) supply these as complete sub assemblies to car builders so perhaps this may be a good place to begin your search.

Good luck , Pete."

HTH , Peter.
