Sounds like your releaser is not working right if it let sap get to the pump or a large quantity of sap came in and flooded it. Make sure your it is level and all the moving parts are lubed up with some food grade grease or silicon. The pump can be fixed. Pull off the end plate on the side opposite the pulley. Look in and see if the sap turned into syrup and has gummed everything up. Then pull the other cap off and take the drum out. Most likely everything needs a good cleaning. Brake cleaner works good. Make sure to clean the vanes and the slots they go into. Make sure the vanes move freely in the slots when done cleaning and put some oil on them. Also, clean the bearings good and oil them up. Chances are the shaft is not bent, but that everything is gummed up so much that it can't turn smoothly. As far as blowing oil out, without an oil reclaimer, they will do that when they get warm under high vacuum. If you get your pump fixed, I suggest adding an reclaimer.
