Info on Recirculation 1073 pump

I can't access the search function so I wanted to ask anyone including Roger , any info good or bad on the Tunze Recirculation 1073 pump? I slightly remember a few years ago when the pump first came out that there were problems with noise and also the impellar shaft.

I have a Blue Line 40HD (21ft pressure rated 780pgh) pumping up one story, a Panworld 20 (480 gph) pumping back up 6ft to an aux tank from the same sump & an Eheim 1262 (960 gph) feeding a Deltec AP902 also from the same sump.
Wanted to see if the Tunze 1073 can replace these 3 pumps at 120w usuage.

The RD pumps are out of my range and not sure if 3.5 meters is enough pressure for my purpose.

The main advantage of the 1073.090 is energy efficiency. It is not a bad pump but unless I was paying more than 25c a KWH I would probably consider other options. You might also consider that it is very hard to valve off flow to a device and keep it constant, the valve gets jammed, the pump slows down, something like a skimmer should probably really have it's own pump. I have always liked the GRI pumps for being relatively efficient, quiet and easy to work on. The 1073.090 has a ceramic shaft and there is enough of a learning curve to getting it apart without breaking the shaft that we now include a spare in the box. If you don't clean them every few months the rotor will cement to the shaft by calcium build up. I don't have a suggestion for the Blue Line as to pump that high will require an energy hog pump, I might try to find one pump to replace the panworld and Blueline and run the skimmer from a 1073.040 which I can whole heartedly recommend and will use half the power of the Eheim though it pumps about 200gph less.

Thanks for the reply Roger.
I will definitely take up your advice on the 1073.040. The 1073.090 is a bit more maintenance then I would like for a return pump. With the magnetic type pumps, I honestly do not take them apart for maintenance at all.
