I have 2 old B&G pumps that are Factory GREEN - not red.  They are model PV-5.  Vertical marathon motors supported on on springs. 
Can anybody tell me approx year and supply a link to original catalog and pump curves? 

I also have an old B&G pump with a horizontal 1/6 hp motor.   It has a 189103 bearing assembly.  How do I determine the actual pump model?

    The horizontal motor pump looks like it has some #s on it. @DanHolohan is the expert on those pumps maybe he will respond

    Horizontal kinda looks like an LD 2-1/2 or 3 but as Dan says maybe a Pd. Never seen the B&G old vertical, worked on many old Thrush and Edward's verticals. Pretty cool.

    It should have LD Or PD cast into veloute. Or just 2 1/2. We still stock 100s of parts for b&g parts and fix them weekly. They really were good pumps. Maybe not the.most efficient but long lived. All parts for red pump still available. Pump motors although are $$$ for a 1/6 hp motor comparatively to cartridge circs.

    I'm going by the bearing assembly. I recall the PD used that one. Gotta stretch my memory pretty far to pull that one out.

    The old B&G P1-5 was a 1/6 HP horizontal pump with a 4 bolt circular flange 1-1/4". I have never seen a vertical version of it before. The earliest B&G Forced Circulation boosters were horizontal with the direction of flow from the sides instead of top to bottom so I guess it wasn't much of a stretch to mount them vertically. amazing to see the OG B&G Logo on that pump! A modern B&G HV Series circulator would replace it, the performance will be close enough. Note that the modern 1-1/4" flange is oval two bolt. The second pump is a much more modern 2 NFI with an all bronze bearing assembly used as a replacement. Assuming both applications are for heating and not plumbing. Also assuming from the age of this post that this has all been resolved by now.
