Looks like the AHS pump to me.  And, why are they painting them black?!

I have not installed the pump yet, but here are a couple of pics of the pump showing the threaded nipple and the brand of the pump.  Anyone familiar with this brand?  The thread is a course tapered one.  There is a zert fitting on the side of the pump about halfway along the shaft for greasing, but no instructions on how often that should be done.  I'm guessing the heater pipe connection is direct instead of the original tap that was screwed into the pump.  Not clear if the tap that Moss sells will thread into this pump and I don't know if I want to spend $160+ to find out.  Is the tap totally necessary?
