Damn! Water got into the vacuum pump

Too much water was stored in the cold trap of the freeze dryer (MODEL CHRIST ALPHA 1–2). I didn’t pay attention when turning on the vacuum pump, and as a result, a lot of water entered the vacuum pump; moreover, a lot of oil sprayed out from the holes in the oil cup. I kept the pump preheating, and gradually the sound returned to being \"normal\" and there was no more oil spraying. Is it really back to normal now? Is there a problem with the vacuum pump? By the way, why is so much oil coming out?

A vacuum pump is used for pumping air, not liquids. In my opinion, it has a significant impact on the lifespan of the diaphragm in vacuum pumps.
