Multiple Flow Electrical Oil Pump

Last update: 03 Sep. 2023

What is Electrical Oil Pumps (EOP)?

Electrical Oil Pumps (EOP) are mainly used in all types of transmissions (Automatic Transmission – AT, dry or wet Dual Clutch Transmission – DCT, Dedicated Hybrid Transmission – DHT, Continuous Variable Transmission – CVT, Manual Transmission – MT, reducer) for lubrication and cooling (gears, clutches, eDrive) and in a lower proportion also for actuation (of clutches, hydraulic gear shifting, hydraulic park-lock). For both of those application fields, Valeo also offers Smart Pump, being EOP (Electric Oil Pump) with a combination of active functions.


What are Valeo Multiple Flow Electrical Oil Pump benefits?
