Wilo Stratus primary boiler pump

[Splashoil]

I have a Triangle Tube Solo 60 with a Hydraulic Separator feeding some old cast iron baseboard and radiators. I went with a Wilo Stratus Pump for that and used a Grundfos 15-58 (speed 1) for the boiler circulator. I then replaced the 15-58 with another Wilo. I set the head down to 4 feet since the 60 output is 55 mbtu on a good day and felt I really did not need the higher flow from the 15-58 even on speed 1.
TT states the 60 needs at least 3 gpm on full output.
Everything is dialed way down with the outdoor reset and a maximum setting of 120F. I’m saving gas compared to the 1974 National cast iron behemoth I replaced. I thought I would try to cut power bills for pumping as well.
I’m on a fixed income with an occasional stimulus check lol. The Wilo has apparently been discontinued? Any reports on performance as a boiler pump? I’ve doubled down on sediment collection and flushed the old cast with fernox. I taped hard drive magnets to my dirt separator and the hydraulic separator too.
I enjoy looking at all the do it yourself installs and comparing them to what Siggy would have done.
12x pipe size straight pipe upstream from a pump seems to be missing from a lot of these creations.

Brief update: The Wilo pump seems to be working well. On the web you can find these discontinued pumps for ~$75!
A great bargain for an ecm smart pump. I'm working on a system sensor install to let the Solo see the temp delivered past the hydraulic separator into the system manifold. The Supply sensor in the Solo will then function as a high limit control.
