Description
Product Overview
The Taco KS2006 is a robust, commercial-grade vertical in-line pump from the renowned KS Series, engineered for reliability in demanding hydronic systems. Designed for both new construction and replacement applications, this pump combines the space-saving benefits of an in-line design with the superior serviceability of a base-mounted, flex-coupled system. It is an ideal choice for mid-sized commercial buildings, industrial facilities, and institutional HVAC systems requiring consistent, efficient fluid circulation.
Its key feature is the split coupling design, which allows for easy disassembly and maintenance of the mechanical seal or bearings without disturbing the motor or piping connections. Constructed with a durable cast iron casing and a bronze impeller, the KS2006 is built to withstand the rigors of continuous operation. The vertically mounted motor on a sturdy baseplate provides exceptional stability, reducing vibration and noise while making it an excellent choice for mechanical rooms where floor space is available but headroom is not a constraint.
For engineers and facility managers who prioritize long-term serviceability and durability, the Taco KS2006 delivers proven performance with the maintenance advantages that minimize system downtime.

Frequently Asked Questions (FAQs)
Q1: What is the primary advantage of the split coupling design?
A: The split coupling allows for easy maintenance of the pump’s rotating assembly (seal, bearings, impeller) without disassembling the motor or disconnecting the piping. This drastically reduces maintenance time and cost, as only the coupling needs to be separated to access the pump shaft.
Q2: Is the motor included with the Taco KS2006 pump?
A: No. The Taco KS2006 is typically sold as a pump-only assembly. The motor must be purchased separately, allowing for flexibility in selecting the exact horsepower, speed, and electrical characteristics (voltage, phase) required for your specific application.
Q3: What maintenance does this pump require?
A: Key maintenance tasks include:
-
Periodic lubrication of motor and pump bearings (if applicable)
-
Inspection and replacement of the mechanical seal if leaking
-
Checking the flexible coupling insert for wear
-
Ensuring proper alignment between the pump and motor shafts
-
Monitoring for unusual vibration or noise
Q4: How do I select the correct motor for this pump?
A: Motor selection is based on your system’s required pump performance (HP). You will need to consult the pump performance curve for the KS2006 to determine the necessary horsepower at your operating point, then select a corresponding motor (e.g., 56J frame, 1750 RPM) from a manufacturer like Baldor, Leeson, or Marathon.
Q5: Is this pump suitable for both open and closed-loop systems?
A: Yes, the KS2006 is designed for standard hydronic applications in both open and closed loops. However, for open systems (like cooling tower service), a suction strainer is highly recommended to prevent debris from damaging the impeller and seal.

Pros and Cons
| Pros | Cons |
|---|---|
| Superior Serviceability: Split coupling allows easy seal and bearing replacement. | Motor Not Included: Requires separate purchase and mounting. |
| Durable Construction: Cast iron body and bronze impeller for long life. | Requires Precise Alignment: Pump and motor shafts must be properly aligned. |
| Space-Efficient Design: Vertical in-line configuration saves horizontal space. | Larger Footprint: Requires a baseplate and more floor space than close-coupled pumps. |
| Reduced Pipe Stress: In-line design minimizes piping strain. | Higher Initial Cost: More expensive than close-coupled in-line pumps. |
| Excellent Stability: Base-mounted design reduces vibration. | Complex Installation: More involved than a simple circulator swap. |
Conclusion & Ideal Use Case
The Taco KS2006 KS Series pump is the ideal choice for commercial and industrial applications where maintenance access and long-term reliability are as important as performance. Its unique combination of a vertical in-line footprint with base-mounted serviceability offers the best of both worlds.
This pump is perfectly suited for:
-
Commercial Building HVAC Systems
-
University and Hospital Central Plants
-
Industrial Process Cooling Loops
-
Retrofit Projects replacing older in-line pumps
-
Any application where minimizing maintenance downtime is critical
If you need a workhorse pump that won’t leave you stranded during critical seasons, the Taco KS2006 with its service-friendly split coupling design is a smart and reliable investment.
