Taco 007

Unknown

a 007 circ will run 40F OVER AMBIENT WATER TEMP.

It will be TOO HOT to touch.

Hot stuff...

My step-father and I put in a wm-ultra this weekend, and everything seems to be running fine, but the 007 circulator that came with it gets HOT, like it hurts to touch it hot. Is this normal?

Thanks,
Ryan

All water-lubricated circulators get hot

This is normal. It may bring to mind why it is maybe too hot, could your HW discharge settings be higher than necessary?

The circulator does create heat of it's own and the surface temperature would be somewhat higher than the water inside it. The lower your water temperature the cooler the circulator will be -and the more energy you will save assuming it still heats your house!

Brad's correct.

When I first installed a wet rotor pump, that was my concern also. Taco advised that it's normal as long as you are within operating specs. of the pump. See literature.

240 degrees max operating temperature

The 007, or any of the wet rotor pumps run hot, but that is normal, and will not be a detriment to the pump.

A hot 007

One thing to check is if it is circulating water. I was called to a new job of another contractor because he could not fix it. He was not circulating water, circulator was hot, but when you put a screwdriver to it as a stethescope you heard humming not water movement. This was caused by a glob of solder that had worked its way thru the baseboard and jammed up the rotor. The other guy refused to think that the circulator was not circulating.

Taco 00 series will run hot when running at long periods of time. When the pumps are "air locked" the temperature will be very hot. We just installed a taco 1919c1 circ that locked rotor on us and pulled 41 amps on the amp meter. That pump was so hot we couldnt remove it till it cooled down.

air eliminaton is KEY....

WET ROTOR NO LIKEY AIR.

the plastic impellers aint all that keen on "debris" wood chips Christmas tinsel)from reaming ( solder foam in the pipe cement sheetrock slerm those things make the pump slave overtime... flushing the system proper air elimination(even on potable) all out removal of the cartridge and impeller will often bring things back to reasonable temps at the pump.

large pumps 20 HP and there abouts are designed to leak slightly to lubricate the shaft of the pump over tightening the packing causes binding and additional "heat" due to friction ...i have repaired a few pumps that were bound this way.the motor drags and overheats causing thermal overloads.....
