I've put 2 cartrigdes in my 011 in 5 years I've owned it and now it is acting up again. Is there a different brand pump that is better quality then the 011? It seems that it always has problems after not running for the summer. I also have two 007 Taco pumps in my system and have never had a problem with them.

What kind of a system is the pump installed on? Is it an open design like an outdoor wood stove?
Also what size line is it pumping into and what is the length?
Also what size line is it pumping into and what is the length?
I have an outdoor wood boiler that has a pressurized system. I have it plumbed primary/secondary and the 011 is run all the time in my primary loop. The system was designed by a heating and cooling engineer and works quite well, but I've had problems with my 011. A few years ago I remembered some posts on other people having troubles with 011 pumps.
So....back to the line size and length.?
If it's a sealed system there should be no issues with maintaining some pressure on the inlet of that high head pump.
Water quality could still be an issue though. What does the inside of the circ look like? White? Black? Rusty?

When you say "trouble" are you talking seizure after the pump's summer off? If it is failing to start in the fall boiler startup, you may be able to simply remove the cartridge and give it a spin to free it up. Most pump control systems have a pump exercise built into the control logic to avoid this. Basically the control system would run all the pumps in the system for a short time either daily or weekly.
We need more info about the line length, size, water chemistry, and circulator failure type. Personally I've had very good luck with Taco circulators.

What owb is pressurized?
Without more info can only speculate too long of a run for 1" line on boiler to house loop whereas the 007s are for zones.

Both times I had to put in cartridges was after the pump has sat for the summer. One time I was able to just spin the impeller and then it worked.
Vince,
If you are just looking to try another manufacturer, there are several out there. Note that as others have alluded, it may not solve your problem. But, here are a few to look into:
Grundfos UP 26-99
Wilo Star 30
Bell and Gossett NRF-33
Armstrong Astro 50
Note above model numbers are pure guesstimates, so use at your own risk.
For sizing your pump to your exact needs, you can check this out if you feel like doing some calcs... http://s3.pexsupply.com/manuals/1350570919940/83616_PROD_FILE.pdf

Or.......Go to a Variable speed pump Like a Wilo Stratos1.25x3-25. They have far more starting torque than any wet rotor pump has and will draw about 25% of the current that 0011 or anything comparable to it.
Heaterman, would there be any gain to that benefit for a pump that runs 24/7 during the heating season? I dont have any experience with the VS circs, so I dont know if the loads kicking on/off would impact the draw on the pump at all.
