I just found the pump online Bell and Gossett NRF-22 for $100. They quoted us $320 for the pump and $150 for the labor!, Am I missing something here?
Do I need parts like gaskets and stuff that aren't included in the websites online?
Actually that sounds about right,my buddy is in the business and I asked him about your boiler and he told me if it was just the pump it would be a 400$$ plus job!
Their markup on the pump is abit too much,if you can get it for 100 bucks it should be a 200 to 250 price range,someone has to pay for those fancy work trucks....

150 dollars is about standard for a 1 hour service call,my buddy charges me about 75 bucks to drop by for a beer,oh and he might check my system while he's here....

Nef, do yourself a favour,get the flanges and gaskets and just replace it all! shouldn't take more than 20 mins to R and R the pump. Spray some WD40 or other rust remover before you try to loosen the bolts and as someone already said disco the power!
If you know someone who knows anything about bolers,have them check the flame! The manifold has a air/fuel mixture adjuster and tuning the flame can make a huge difference on your heating cost!
Oh and I called my buddy to do a tuneup on my system,that when I asked about your boiler!
YMMV.
