Narrative:
On climbout/normal departure passing approximately 13;000 feet MSL; the 'B' hydraulic system engine 2 pump low pressure light illuminated. The QRH was complied with. A minute or two afterward; the 'B' system electric pump low pressure light flickered and then remained illuminated. We checked the hydraulic gauges and noted the 'B' system needle was erratic and then settled between 1/4 and 1/2 full. The first officer continued flying and communicating with ATC. The flight attendants were notified. I addressed the QRH for the 'B' system failure. We initially leveled off at 16;000 feet MSL and then continued to FL220. Coordinating with dispatch and maintenance; the 'a' and standby hydraulic systems functioning normally and after working through our malfunction; being near the halfway point; I decided to continue to our destination and a longer runway. The QRH checklist was completed and reviewed and a request was made with approach control to have emergency equipment standing by as a precaution. Transfer of control of the aircraft was accomplished; landing and go-around procedures reviewed; and an uneventful flaps 15 recovery was made. Maintenance was at the gate to receive the aircraft.
