Neither are particularly long in the tooth then (mileage-wise)

Nope, but it doesn't take much for the pump to fail. Typically, the gears will wear on each other within the pump and the swarf from this will stick the PRV open.

This stops the pump building pressure to circulate and the pumps had it. Probably won't take much discrepancy in the design tolerance of the gears turning at 3,000rpm for 100,000 miles before things start to wear and this happens...
