Not likely. Once the system is under pressure, the pump will only leak.

Subject: water pump

Good evening Volks,
I would like to pose a question to the collective wisdom of the list.
Could a water pump draw air into the system? I have been fighting air in
the
system for little over a year. Not much,about 10 seconds of air out of
the
bleeder, rising
over flow tank. I am paranoid and i check every week after reading posts
on
the list. I know that it is a good chance that I am getting combustion
gases
in(208,000. on the clock)
but can the pump be adding to the mystery. I have done compression tests
(125-140)
 and no change seen on the leak down .
