Product Highlights
Description
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 the 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.

Product Q&A
7 QuestionsQ: What is the GPM on each speed?
Asked by Ron 12 years ago

Verified Reply- Supplyhouse StaffThe variable speed delta T model pumps shift their performance automatically based on the supply and return temperature sensor readings. The 007 model works on or under the standard 007 pump curve. They do not have selectable speed modes.
Q: Will this pump work on a solar drain back system? And will one of the sensors be attached to the top of the solar panel---and does it come with (2) 10K sensors?
Asked by Solaray 13 years ago

It depends on what you need for a head. See the Taco pump head vs flow rate figure below for curve 5. The head on this pump won’t do if for instance the panels are mounted on the roof because it runs out of head at 10 feet which is likely not high enough for most roof mounted applications. If however the panels are ground mounted then you may only have a 3 or 4 foot head, so the pump will flow around 16 gallons per minute. I don’t know the size or quantity of your panels and can’t say what you’ll need for flow rate. The pump does come with the two thermocouples and can maintain a deadband for automatic start/stop applications. I have a 007 delta T that I was going to use but the head for my application was too much the 007 pump. Furthermore these circulator pumps are typically used in a pressurized system for heating systems around 12-15 psi. I wound up using a 0013 pump in an open reservoir closed loop system for a garage radiant floor heating application and that pump worked very nicely as it is 33 ft head capable vs 10 ft for the 007, however I need to get some pressure to make the electric heater turn on and the 007 wasn’t able to build enough pressure. If you think you can use the 007 delta T, I still have the one I was going to use for the radiant system that I can give you a deal on, it’s brand new from Pex Supply.
Q: Does this pump come with a IFC.

Verified Reply- PexSupply StaffNo, this pump does not include an internal flow check.
According to PexSupply product listings the 007 with delta-T is not offered with IFC.
Only if you order it with IFC.
Q: Are the Flow Range, Head Range and Max psi specs the same as listed for the 007 single speed circulator?
Asked by 15 years ago

Verified Reply- PexSupply StaffYes, the pump operates under the same pump curves and ratings.
Q: Will this pump stop when the two sensors get to the same temp. The instructions say that you can change the minimum speed but I want it stop and wait until the temp drop rises again then continue pumping. Thanks.

Verified Reply- PexSupply StaffThat depends on the setting of the delta-t control.
Q: My current pump is installed on the return to boiler. Can this pump be installed in the same location.

Verified Reply- PexSupply StaffYes, you can install this pump on the return to the boiler.
Q: I have a standard 007 circulator in use now and would like to change to a variable speed circulator. are the motor cartridges the same to easily rebuild like a standard circulator or are special parts needed ?
Asked by 15 years ago

Verified Reply- PexSupply StaffThose circulators have the same type of cartridge.
Not only are the cartridges the same. The housings are the same,just bolt up the new motor to the existing housing. That was the question I asked Taco.
