You would not seal a sump pump. If it's a below ground tank, with a
bolted on cover and pipes coming up through rubber bushings, it would
likely be an ejector pump for sewage. If you're looking at a 4" PVC duct
coming out of the concrete, it's probably a radon system. The blower for
the system could be outside the house, or in some remote location

Sumps _are_ sealed for radon mitigation.

My sump cover is sealed and has a PVC pipe coming out of it through the roof
for passive radon removal. What's dumb about the setup is that the cover is
sealed but has a 2" diameter circular hole in it.
