Taco 2400-40S-3P Stainless Steel Circulating Pump | Ultimate Product Guide

The Taco 2400-40S-3P is a heavy-duty, stainless steel circulating pump from the renowned 2400 Series, engineered for the most demanding commercial, industrial, and chemical applications. This model is constructed with corrosion-resistant stainless steel wetted parts, making it ideal for handling aggressive fluids, acids, caustics, and solvents that would rapidly degrade standard cast iron pumps.

Powered by a robust 3-phase motor, this pump is built for continuous duty in harsh environments. Its defining feature is the full back pullout design, which allows for complete maintenance of the seal and rotating assembly without disconnecting the motor or piping, drastically reducing downtime. Whether for chemical processing, industrial washdown, or specialized HVAC applications, the Taco 2400 Series delivers unmatched durability and reliability.

Detailed Technical Specifications

Note: The “40S” in the model number typically indicates specific performance characteristics (e.g., impeller size, port size). Always consult the factory curve for exact GPM and Head specs.

Key Features & Benefits

• Stainless Steel Construction: Provides superior corrosion resistance for handling acids, caustics, solvents, and other aggressive fluids.

• Full Back Pullout Design: Enables complete service of the seal, impeller, and bearing frame without moving the motor or pump volute.

• Three-Phase Power: Offers higher efficiency, simpler design, and greater torque for industrial settings.

• Industrial Duty: Designed for continuous operation in the most demanding environments.

• Baseplate Mounting: Provides a stable, secure foundation for heavy-duty service.

• Seal Flexibility: Can be configured with various mechanical seal materials to match the pumped fluid.

Frequently Asked Questions (FAQ)

Q1: What specific type of stainless steel is used?
A: Taco typically uses 316 stainless steel for its superior corrosion resistance, especially against chlorides and acids. However, for the exact specification (e.g., 304 vs. 316 SS), you should consult the official Taco specifications or product data sheet for the 2400-40S-3P model.

Q2: Is this pump suitable for potable water?
A: While stainless steel is generally excellent for potable water, the pump’s suitability depends on the specific grades of stainless and seals used. If needed for drinking water, you must confirm that the pump meets NSF/ANSI 61 or other relevant potable water standards. It is primarily designed for industrial process fluids.

Q3: What does “full back pullout” design mean?
A: This is a major service advantage. It allows a technician to unbolt the entire rotating assembly (impeller, shaft, bearings, seal) and pull it straight back from the volute (pump body) for service. The motor stays aligned on its base, and the piping connections remain undisturbed, saving significant labor time and cost.

Q4: What applications is this pump designed for?
A: This pump is built for harsh and industrial duties, including:

• Chemical Transfer and Metering

• Food and Beverage Processing

• Industrial Washdown Systems

• Water Treatment and Chemical Feed

• Transfer of Solvents, Acids, and Caustics

• Process Lines in Manufacturing

Q5: What kind of mechanical seal does it use?
A: Industrial pumps like this are often offered with a standard seal. For chemical service, the seal material is critical. It can typically be configured with various seal options (e.g., Viton, EPDM, Silicon Carbide faces) to ensure compatibility with the specific fluid being pumped. You must specify the fluid when ordering.

Q6: Does it require a baseplate?
A: Yes, as a frame-mounted pump, the 2400-40S-3P is designed to be mounted on a baseplate, which is then grouted to a solid foundation (like a concrete pad). This ensures stability and perfect alignment between the pump and motor.

Pros and Cons

Pros:

• Excellent Corrosion Resistance: Stainless steel construction allows it to handle fluids that destroy standard pumps.

• Industrial Duty: The 3-phase motor and robust construction are designed for continuous operation in demanding environments.

• Easy Maintenance: The full back pullout design drastically reduces downtime for service.

• Proven Reliability: Part of Taco’s heavy-duty 2400 Series, known for performance in tough applications.

• Seal Flexibility: Can be outfitted with the appropriate seal for virtually any chemical application.

Cons:

• Higher Initial Cost: Stainless steel construction and industrial features come at a premium price.

• Requires 3-Phase Power: Limits its use to facilities with 3-phase electrical service.

• Not a General-Purpose Pump: Overkill and unnecessarily expensive for simple water circulation in a closed, clean loop.

• Professional Installation Required: Requires baseplate mounting, grouting, and precise alignment.

Conclusion & Best Applications

The Taco 2400-40S-3P is a specialized industrial pump designed for one primary purpose: reliably moving corrosive and aggressive fluids in demanding settings. It is the ideal choice for plant engineers and maintenance managers who need maximum durability and chemical resistance.

You should choose this pump if:

• You are pumping acids, caustics, solvents, or other corrosive chemicals.

• Your application is in food processing, chemical manufacturing, or water treatment.

• You have a 3-phase power supply available.

• Ease of maintenance and minimizing downtime are critical concerns.

For challenging pumping applications where standard pumps fail, the Taco 2400 Series provides a reliable and effective solution.

Disclaimer: Professional installation is required. Ensure the wetted materials (stainless steel grade, seal materials) are compatible with the specific fluid being pumped, including its concentration and temperature. The pump must be wired by a qualified electrician for 3-phase power. Always confirm the specific performance curve (GPM and Head) matches your system requirements.
