Narrative:
At FL310 we had a caution 'hydraulic 1 lo press' message. Followed QRH and the B pump did not function either. The steps led to 'land at the nearest suitable airport' so I contacted dispatch and discussed where to go. It was decided that we would divert to ZZZ. Because the number 1 edp was not working and its' backup was also not working; and the fact that we were diverting; I declared an emergency. Weather was not a factor. The first officer was the flying pilot but I decided that I would perform the landing and did so. Edp 1 failed as well as its backup. Had the B pump worked diversion would not have been necessary. Time is always a factor rushing can lead to errors. The change in mind-set can be a distraction (changing destination getting weather and other data). No undesired states occurred and the first officer and flight attendant both did a very good job dealing with the situation.
