It may seem an odd thing to say but the easiest solution may be to make a simple oscillating cylinder engine and drive it with a small electric motor. This will act as a pump similar to the Hy-flo (Medcalf) aquarium pump that was available in years gone by. There is the matter of sizing everything to suit your needs but unless you are after speed that blurs the motion it should be doable. There are micro vacuum pumps available that could be used as pumps but they may be too weak but if you look them up it may give you an idea of what is needed to make something.
