All this leads me to the conclusion that something is wrong with the
vacuum pump on this station. Would you say that it should provide very
strong suction?

Obviously it should provide enough to remove molten solder from the joint.

Most desolder tools can get blocked. So check the pump with the tool
disconnected you should feel the vacuum with your finger.

I tried it last night, with the tool disconnected, as you say. I do
feel a vacuum, but it is very slight.

Also check the output air stream from the pump. Many have an
adjustable restrictor valve to set the vacuum level. If it's been
used without the proper filters it's possible the pump is dirty,
blocked or damaged. They usually strip down easily. The one Pace
I've had apart had sort of carbon vanes which move in slots to make
contact with the body by centrifugal force. If those were stuck it
wouldn't work properly.

OK. When I get time, I will take it apart and see what's wrong. The
station is usable even without this pump, since I can use my other
vacuum pump (1/3 HP Welsch DuoSeal), but, obviously, it is not as
convenient. I would even say, "it sucks".
