Description
–
Note: Full flange-to-flange three-year warranty on all 00 Series circulators.
Taco Variable Speed Delta-T Circulator's all-in-one design combines a microprocessor based variable speed differential controller with the reliability and convenience of our 00® Cartridge Circulators. Simply dial in the design Delta-T of the system or zone (from 5 - 50°F) and then sit back and watch the circulator automatically adjust its performance to match the systems ideal BTU/hr output, while conserving energy and eliminating velocity noise.
No matter how good your original system design and heat loss calculations were, they included estimates and rules of thumb. What are the design conditions for those systems you "inherited" or have to service? Have a zone valve system or multi-zone radiant manifolds running off a common circulator? Your system needs a circulator that automatically adjusts to deliver the optimal heat transfer based on the actual operation of the system, every day, under all load conditions - even when those conditions change. With the Taco Variable Speed Delta-T 00® Circulators you simply dial in your desired temperature drop across the system or zone (5-50°F), attach a supply and return sensor directly to the pump and it will automatically vary its performance to deliver optimal heat, efficiency and comfort.
Features:
Casing O-Ring: 008-005RP
Flange Gasket Set: 007-007RP
Cartridge Assembly Complete: 008-045RP

Loud buzzing sounds that transmits through walls
The pump makes this humming sound, similar to fluorescent light. The sound changes in pitch depending on which speed the pump is running at. This terribly annoying sound transmits amazingly well throughout my living room from the mechanical cabinet that is in the garage on the other side of the wall. I can also hear it throughout the house if I pay attention. Even though the pump is secured on a perpendicular partition wall with rubber mounts. And the piping is pex, which should further limit noise transfer.
I did set the pump low speed limit to "low" instead of "normal". Which does allow the pump to run even slower than the default. This does reduce the noise significantly when the hydronic system reaches its cruising temperature.
But still, I was expecting something much quieter, as the application sheet clearly state that it is for quiet operation. I bought two of those pumps, at $320 a pop.
Reading online, I am apparently not the only one experiencing this. And some people recommend a competitor brand for truly quiet operation.

Q: Will this pump work with a takagi th3 and a taco zone controller for radiant in closed heating application, or do I need other controls besides the sensors? Thanks
Asked by Mike 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffNo this pump is not rated for the TH3. The user guide states that "the recirculation pump is to provide no less than 2 GPM (7.5 L/min) and no more than 4 GPM."
