Pump Longevity

The Taco 007 circulator between boilers has been in cold weather service for 4+ years now. No stopping, no maintenance, no noise, no sign of failure. Unless I have my decimal in the wrong place that is 17K+ hours of operation. I sit in constant admiration of this design but also wonder just how long this little workhorse can pull the plow. I have a new one on standby but am interested to learn if anyone has an idea how long these 007's last with a 100 percent duty cycle. Mike

6 month winter use only, got about 20 years on first one. I was also told by a plumber that they can be rebuilt, at least the impeller part. But you would have to confirm that.

I have only seen three in the thousands I have been around in over 35 years. Normally those failed due to seasonal lockup and being left locked for weeks before people realized it. Constant run motors are the best application and if you are smart, you will add the taco board to exercise them in the off season if you shut down. PS: The rebuild kit is about the same money as a brand new one......
Also, they are upgraded all the time, so a 007 of 1985 is NOT the same machine as a 2014 unit. More efficient, less power consumption.......so forget the rebuild kit, especially if you can't do it yourself!!!!

Oh No!!!!!!!!! You just jinxed yourself into a failure!!!

The first corollary to Murphy's Law is that any mention of success of a system or component will be shortly followed by a failure of that system or component.

Good preparation that you have a replacement ready! I hope you have some valving in place to make replacement easy.

My experience is they last longer if run continuous, starting and stopping beats them up.

O.K. titleist, stop with that negative thinking son, Breakdowns are not permitted in my boiler room. The system has the valves to make the change out straightforward. I think it is an easy job now but then again if it lasts another 16 years as mentioned, phew, not sure if I will be swinging anymore wrenches in my high 80's. Oh wait yes I will , I forgot about my breaker bars. I'll still be handling coal also just very small teeny buckets.

My former oil boiler system had a B&G NRF22 that ran non-stop for 10 years and never faltered. I should have kept it, but it went out with the oil boiler.

Set up an auger or conveyor so you WON'T have to touch it, and when you stiff-out, they can throw you on the conveyor to the Crematory........Plan Ahead!!!

All I can add is to use a quality anti seize on the fasteners when you install a pump...also check them a few weeks after the install to see if things are snug.
