Title: Taco Pumps
Post by: wrudoing on November 01, 2011, 06:58:19 PM
My 6048 has been fired for two weeks now and another 009 bites the dust this will make the fourth one in a year. I have two pumps on the boiler,  last year i replaced one of them 3 times now the other one,  it has the electrical burning smell going on.  Are I the only one with this problem  HELP!!! ???

have you ever checked voltage ?  even if it was undersized you wouldn't be burning up the motor.

Why are you running an 009? 008, 009 and 010 are really bad choices for OWB. An 007 will flow the same or more water in most setups as any of them.
If using taco, I would only consider 007, 0011 or 2400wb

I have had the impeller lockup twice on mine during start-up situations. I took pump apart and helped the pump rotate some then was ok. Taco pumps do not like the down time during the summer..

 Yeah Id have to agree with rosewood..A undersize pump wouldn't burn up...A undersize pump just wouldn't keep up with demand.. Sound like a electrical problem or something like that...Cheapest place Ive found for pumps is www.altheatsupply.com (http://www.altheatsupply.com)  esp for 011 pumps

Dealer recomended 009, and it has been sitting all summer, it's all warranty stuff still, I talked to the dealer this morning and he is replacing it with a different brand I have no idea what it will be yet. Will post later

Well the pump was stuck which burnt the motor up. He ended up putting another 009 on?? Water tested okay,  What i don't understand is the thing has been running non stop for 2 - 3 weeks now how does the pump get stuck when it's running i can see at start up after sitting all summer? Is there any maintance that should be done that I'm unaware of?

As commented before TACO pumps don't like to sit. Before I knew that I put mine on a 2 hour/day timer over the summer.  Now I'm glad I did. (mine is a 007)

my taco is an 0011 this is year 11 and i shut it off in late april or june and turn it back on near the end of october..have never started it in the summer months and have never had a problem with it (yet) i do have a filter right after the pump to prevent my rads from plugging up and maybe that helps as less (junk) would be recirculated through the pump. could it be your pump is undersized and fails to move enough water and at times could be cavitating and causing overheating of the pump to the point that it is not being properly lubricated by the water?

The pump is 25' from the exchanger don't think it's overworked?  What is the difference between 009 and say the 011?  I'm thinking it's motor and pump sizes?  school me on this

Interesting, 009= 8GPM 35' head height what should your GPM flow be? I'm not lifting 35' maybee 10' max. One pump is actually higher than the exchanger. Looks like the 007 is a 20GPM and 11' head height.   Pros and cons on flow rates??
Title: Re: Taco Pumps
Post by: RSI on November 02, 2011, 06:19:05 PM
The head feet isn't how high you are lifting, it is the restriction in the line. The pipe, elbows, heat exchangers, etc give some head loss. The return water in the return pipe acts as a siphon so you aren't actually lifting the water at all after the air is out even if the house is way higher.
The head pressure loss gets higher as the flow rate increases so it is hard to calculate. An average forced air heat exchanger loses about 1/2 foot at 5 gpm and about  2-1/2 feet at 10 gpm.

See, thats why i don't have the right pumps because i had no idea what i needed,  looks like the dealer doesn't understand the differences either. I'm running 4 of these pumps,  they have only been lasting a few months anyway I'll start changing to 007 or 011 as they give up the ghost :-\

I would switch to Grundfos 15-58 pumps. They are about the same price as an 007 and have a higher head pressure.

The dealer just keeping new pumps on mainly because they have a 3 year warranty but he told me he would put whatever i want on,  but i did not have any idea what to suggest. I'll ask him to get a couple of the grundfos pumps in, they always go out at the worst possible times.

Few yrs back my buddy bought a new OWB....Got ready to fire it up for the 1st  time..The 007 was seized up..Had to put a new pump on...Course he got reimbursted for a new pump... www.taco-hvac.com (http://www.taco-hvac.com) will give you the stats for all the pump sizes....Cheapest place to buy a 011 pump that Ive found is  www.altheatsupply.com (http://www.altheatsupply.com)

Well, i came into work this morning and the remote readout said 131 degrees and i thought wow it burned some wood last night so i went to reload and the wood that i put in last night was still there maybee fired once over the night. The furnace said 180 started looking and both pumps were dead by that i mean mumming and not pumping!  This makes 6 dead pumps in a year number 7 and 8 are going on this afternoon. The dealer sent a few of the bad ones back to taco and they thought failure was due to mineral build up? The last pump only had 5 days run time to build minerals up and stop the pump :-\   We are in the process of draining the burner, i guess CB has a water softner kit that you hook to your hose and is good for 500 gallons we are going to try that with new additive and 2 new pumps. Sure glad it's not January and -20 today :thumbup:

Two new pumps new soft water and refired happy tonight ;D   The old pumps were both real crusty sounding when you turned them the water that came out looked clear no floaties or anything,  Hope this is the fix!!

Well new pumps have been running 2 days now until this morning one was not running bumped the power cord and it came back on, i took the cover off and the receptical was definatlly not in god shape,  as i was replacing the receptical the thing just fell apart in my hands. My thinking is the heat off the pumps broke down the adhesive and made the receptial brittle?  Not a big deal to replace but something to  watch and be aware of.  My OWB is 1 year old ???

Well it's  been almost 2 months since I had all my pump problems since changing the water out using the CB water softner cartridge  I've had zero issues, i believe the water quality and/or the minerals in it combined with the heat mess with the pumps.

Yeah Im sure that water quality has affects on the pumps

Did you take any of the failed pumps apart? I haven't taken a Taco apart recently but have other brands. It is pretty easy to see how dirty water could kill wet rotor pumps.

Hopefully that takes care of your problem for good.

Yea, the last 2 pumps went out at the same time 1 was 7 days old they were gritty as you turned them and the stems broke after a few turns. The water was clean there weren't any floaties looked like regular water, but we have super hard water lots of iron if i would have known i would have had water hauled in,  The dealer set a couple of the previous failed pumps in to Taco the failures were casued because of calcium deposits,  the softner cartrage from CB is new this year and wasn't available when i did my setup. Conditioned water is Super important especially where the pumps are concerned.

              009 Taco pumps
              I have 4  009 Taco pumps.I run three on a start and stop basis with 120volt power controlled by relays that the thermostats open and close.The other pump is my spare for quick change.They have been in service since 1993 and each has had a new motor/impellar assembly in that time.They run from October to June each year and sit idle during the warm months.My pipes are all 3/4" and the only failure I recall was caused by crud in the impellar that jammed the pump.In my opinion,it is important to put their suction on the bottom of the boiler and have them return to the top of the boiler.In the new Shaver 250 I just installed,I put brass traps in the suction between the boiler and the pump.One system pumps about 260 feet round trip.One pumps about 250' and the third one about 150' round trip.-----shorman.
