During climb out from ZZZ; passing FL330 we noticed the Master Caution light flickering. We discovered it was the Low Pressure light for Hydraulic System A Engine Driven (ENG 1) pump. After leveling at FL370 the ENG 1 low pressure light then came on steady. We executed the checklist and turned the pump off. We then referenced the Hydraulic quantity and noticed the A system quantity was at 20% and B system was at about 88%. The quantity in system A then continued to decrease; reaching 0% within a few minutes. The System A ELEC 2 low pressure light was not illuminated at this point. We decided to divert to ZZZ1 and advised ATC. We reviewed the Loss of System A checklist and planned our diversion to ZZZ1. On downwind for Runway XX in ZZZ1 we lowered the gear early as planned. After the gear came down we got the low pressure light for the System A ELEC 2 pump. We completed the checklist for Loss of System A and continued our approach. After landing we discovered the Alternate Nosewheel steering was not working. We stopped the aircraft on the runway. We checked the hydraulic quantities and noticed the system B quantity was now at 47%. We were subsequently towed to the gate.
