Bell & Gossett e-1510 1.5AD 1-1/2 HP Pump | Ultimate Product Guide

The Bell & Gossett e-1510 1.5AD represents the pinnacle of modern, high-efficiency pumping technology for commercial HVAC and plumbing systems. This 1-1/2 HP, 1750 RPM, 3-phase end-suction pump is engineered from the ground up to minimize life-cycle costs through dramatically reduced energy consumption. As the flagship of the redesigned Series e-1510, this model leverages cutting-edge computational fluid dynamics (CFD) to create the largest “Efficiency Island” in its class, ensuring superior performance across a wide range of operating conditions.

Beyond efficiency, it is built for unparalleled reliability and serviceability. Key features like the True Back Pullout design, an internally self-flushing mechanical seal, and the optional i-ALERT2 condition monitor make this pump a smart, long-term investment for system designers and facility managers who prioritize performance, sustainability, and low total cost of ownership.

Detailed Technical Specifications

Key Engineering Features

• True Back Pullout: Allows servicing seal and bearings without disconnecting piping or moving the motor.

• Center Drop-Out Spacer Coupling: Simplifies maintenance and reassembly.

• ANSI/OSHA Compliant Coupling Guard: Standard safety feature.

• Optional i-ALERT2 Monitor: Provides real-time health data (vibration, temperature) for predictive maintenance.

Frequently Asked Questions (FAQ)

Q1: What does “TEFC” mean for the motor?
A: TEFC stands for Totally Enclosed, Fan Cooled. This means the motor is completely enclosed to prevent dust, moisture, and corrosive fumes from entering, making it ideal for harsh industrial and commercial environments. An external fan blows air over the motor casing to keep it cool.

Q2: What is the advantage of the “True Back Pullout” design?
A: This is a major service advantage. It allows a technician to disassemble the entire rotating assembly (impeller, shaft, seal, bearings) by simply unbolting the cartridge and pulling it straight back. The motor stays perfectly aligned on its base, and the piping does not need to be disturbed, drastically reducing maintenance time and cost.

Q3: Is this an ANSI pump?
A: While it shares many dimensional and interchangeability standards with ASME/ANSI B73.1 pumps, the e-1510 series is Bell & Gossett’s own advanced design. It incorporates ANSI-compliant features like a standardized coupling guard but exceeds standard specifications with its efficiency and built-in features.

Q4: What is the “i-ALERT2” sensor?
A: This is an optional, patented condition monitor that mounts to the bearing bracket. It continuously measures vibration and temperature, providing a visual warning (via LED lights) for impending bearing or seal failure. This enables predictive maintenance, allowing repairs to be scheduled before a catastrophic failure occurs.

Q5: Can this pump be used with potable water?
A: While highly efficient, the primary pump construction is cast iron, which is not certified for potable water applications due to potential rust contamination. It is designed for closed-loop heating and cooling systems, condenser water, and other industrial applications.

Q6: Why choose a 1750 RPM motor over a 3500 RPM?
A: A 1750 RPM motor operates at a slower, less stressed speed. This results in longer bearing and seal life, significantly quieter operation, reduced wear, and often better energy efficiency compared to a noisier, higher-wear 3500 RPM pump of similar capacity.

Pros and Cons

Pros:

• Unmatched Energy Efficiency: CFD-optimized hydraulics provide the highest efficiency in its class, leading to substantial electricity cost savings.

• Superior Serviceability: The True Back Pullout design and drop-out coupling make maintenance faster, easier, and cheaper.

• Extreme Durability: Built with a heavy-duty baseplate, solid-foot volute, and a robust TEFC motor for a long service life in tough conditions.

• Smart Monitoring Ready: The option to add i-ALERT2 transforms it from a dumb pump into a smart asset for predictive maintenance.

• Quiet, Reliable Operation: The 1750 RPM speed and computer-balanced impeller ensure smooth and quiet performance.

• Proven Brand Legacy: Backed by Bell & Gossett’s century of expertise in fluid handling.

Cons:

• Higher Initial Cost: The advanced technology and premium efficiency come with a higher upfront price tag than standard pumps.

• Not for Potable Water: Cast iron construction limits it to non-potable applications.

• Requires 3-Phase Power: The three-phase motor requires a commercial/industrial electrical supply.

• Professional Installation Required: Proper alignment on its baseplate and piping connections requires a skilled technician.

Conclusion & Best Applications

The Bell & Gossett e-1510 1.5AD is not just a pump; it is a system efficiency upgrade. It is the optimal choice for engineers and facility managers who calculate Total Cost of Ownership and prioritize long-term energy savings and reliability over the lowest initial purchase price.

You should choose this pump if:

• You are designing or replacing a pump in a commercial HVAC system (chilled water, hot water, condenser).

• Energy efficiency is a primary goal to reduce operational expenses and environmental impact.

• You want to enable predictive maintenance and minimize unplanned downtime with the i-ALERT2 option.

• You need a reliable, serviceable workhorse for an industrial or plumbing application.

For the ultimate combination of efficiency, reliability, and smart features, the B&G e-1510 series is the definitive choice in the end-suction market.

Disclaimer: This pump requires a 3-phase power supply and professional installation. Always ensure the pumped fluid is compatible with cast iron. Specifications are subject to change; always confirm details with official Bell & Gossett documentation or a authorized distributor.
