How Taco 00 Series Pumps Improve Efficiency in Water Systems

In water system applications such as space heating, chilled water, radiant floor heating, and domestic hot water circulation, the circulator pump plays a critical role in achieving high system efficiency.

The circulator is responsible for moving water through all major components, including boilers, chillers, valves, tanks, and heat exchangers, making pump selection and operation essential to overall system performance.

Taco 00 Series Cartridge Circulators: Models, Materials, and Configurations

The Taco 00 Series Cartridge circulator is designed to work efficiently across a range of water system applications. With several casing arrangements, it's also suitable for specific systems that demand stainless steel construction.

The main feature is the unique replaceable cartridge, which houses all the pump's moving parts and allows easy service without a complete circulator replacement. Another key feature is the option for an integrated IFC (Integral Flow Check), which eliminates additional installation costs and reduces the space required.

Below is some more information about the 00 Series Range:

Replaceable Cartridge

The replaceable Taco Cartridge in the pump design makes this pump space-efficient for easy service and installation. This unique feature houses all the moving parts, enabling maintenance without replacing the entire pump.

The following video shows how quick and easy it is to replace the pump cartridge:

Integrated IFC (Integral Flow Check) as Optional

The Taco 00 Series has IFC as an option; it's a welcome feature, especially when a compact system is in place. Also, this feature avoids additional cost with valves and pipes.

IFC - Integral Flow Check for Taco 00 Series Pump

If the pump includes the IFC feature, it's installed directly in the pump's water line. The IFC will generate a pressure drop in the system, and the pump's performance will differ from that of the standard version. Below the pump curves are amended considering the IFC integration:

How Taco 00 Series Pumps Improve Efficiency in Water Systems

We've had a look at the main features of the Taco 00 Series, and now let's connect the points and understand where they can be an active component to improve efficiency in water systems.

Right Size For the Right Flow

The first aspect that affects the efficiency of any water system is selecting the optimal pump size based on system demand.

A well-sized pump can reduce the power consumed by 20% and avoid other problems that can affect the entire system; for example, an oversized pump can increase water velocity and pressure, leading to premature failure of valves or heat exchangers.

When a low or medium water flow rate is required, the Taco 00 Series offers a wide model range to ensure an optimal operating point, as previously mentioned.
Below is the general performance data for the Taco 00 Series:

Flow Range: 0-52 GPM
Head Range: 0-35 ft
Power Range: 1/40 - 1/6 HP
Maximum Working Pressure for Low Water Flow rate Range: 125 PSI
Maximum Working Pressure for Medium Water Flow rate Range: 150 PSI
Minimum Fluid Temperature: 40°F
Maximum Fluid Temperature: 220°F

Low Electrical Consumption

Taco 00 Series pumps are equipped with low-consumption Direct Drive motors, which, when properly sized, deliver highly efficient power output. The DD motor is also placed in a compact housing, which facilitates maintenance.

Maintenance Efficiency

As mentioned, the pump design uses a unique cartridge housing for all the pump's moving parts; this feature improves maintenance by eliminating the need to remove the pump in case of moving parts failure.

Another aspect is its compact construction, with different material variations available, accommodating several applications while maintaining a small installation space.

Integrated IFC

Taco 00 Series Cartridge pumps can be delivered with an integral IFC (Integral Flow Check) as an option. It is installed at the pump inlet or outlet. It prevents reverse flow and gravity circulation when the pump is not operating, protecting system performance and eliminating the need for external check valves. This arrangement improves system performance due to its compactness and reduces maintenance.

To demonstrate how this feature can improve the efficiency of your system and how it can make your maintenance easier, you can find below the IFC step-by-step replacement recommended by Taco:

Removal:

Disconnect power to the circulator and related equipment.
Shut off the water supply. Isolate the circulator using service valves or the drain system if service valves are unavailable.
For models listed in Figure 3 below, remove the motor housing by loosening four cap screws.
For models listed in Figure 4 below, loosen flange bolts and remove the entire circulator from the system to access the IFC.
Using needle-nose pliers, carefully grip the IFC’s body and slowly remove the IFC.

Replacement:

Make sure the IFC pocket is clean and free of any debris or particulates.
Position the IFC into the machined pocket inside the casing as shown in the diagrams below. Firmly press the IFC into.
Replace O-ring and reattach motor housing, or reinstall entire circulator with new flange gasket.
Open water supply and refill system. Check for any leaks.
Reconnect power to the circulator and check for proper operation of the system.

When is the Taco 00 Series the best pump circulator choice?

We've outlined most of the benefits the Taco 00 Series Cartridge pumps can bring to your installation and how their features can improve your water systems in your application. Based on the features outlined above, the following points can help determine whether the Taco 00 Series is the right choice for your application:

The water system design (water flow rate, required head, water temperature, and operational pressure) must be aligned with the minimums and maximums for the 00 Series range. It's crucial that the range fully meets your design needs for optimum operation.
If you have a compact installation room with limited maintenance space, the Taco 00 series is highly recommended due to its cartridge arrangement, as mentioned in this article.
These pumps are highly recommended for domestic systems (domestic hot water or even potable water application) due to their quiet operation and easy maintenance.
Another case where these pumps can shine is when you have limited pipework space; the version with integrated IFC will save you some meters of installation and can be very useful in domestic and small water systems.
An application where these pumps are widely used is in closed loops feeding small water-source heat pumps and chillers, as a constant flow rate is typically required. When well-sized, these pumps can deliver a highly efficient solution that occupies a tiny footprint in the plant room.
