On climb out of ZZZ to ZZZ1 ferry flight at FL 380 we received an Engine Driven hydraulic system low pressure light on B system. Ran QRH Procedure and continued. At FL 410 we received an Engine Oil Filter Bypass indication on forward panel. Ran QRH Procedures; which led us to an engine shut down. [Advised ATC] and requested return to ZZZ. As we turned towards ZZZ; we received a B system electric pump low pressure light with no hydraulic fluid remaining. Ran QRH for B system failure and reviewed our procedures.Returned to ZZZ (longest runway). Advised ATC; Company Operations; Maintenance and Dispatch of both failures.Complied with QRH; landed and taxied to gate uneventfully. Made appropriate ELB entries; spoke to Maintenance and Dispatch to verbally confirm entries and events.
Approximately 150nm East of ZZZ climbing through FL380 we noted an Eng 2 Hyd Press Low Light. We ran the QRC and turned pump off per checklist.15 mins later level FL410; we noted No.2 Oil Filter Bypass Light. We retarded the throttle to idle. The Oil Filter Bypass Light stayed illuminated at idle. The checklist led us to Engine Failure or Shutdown Checklist.We shutdown the No.2 engine. After completing the checklist; we noticed the No2 Electric Pump light on. We checked the hydraulic quantity and found the hydraulic quantity at zero.We the ran the Loss of Hydraulic B System Checklist; advised ATC; returned to ZZZ for an uneventful landing.
Flight Crew reported #2 engine driven pump failed; causing loss of B hydraulic system requiring an inflight shutdown of the affected engine and an air turnback and precautionary landing.
