Taco 1611E3E1 1600 Series In-Line Centrifugal Pump 1/2HP 3PH

Circulate industrial HVAC water with Taco 1611E3E1 1/2 HP three-phase in-line centrifugal pump for closed-loop heating and cooling. Its 208–230/460-volt motor runs at 1,725 RPM and delivers up to 85 GPM with 40 feet of head. The 1-1/2-inch two-bolt flange and 12-inch flange-to-flange length help contractors verify replacement fit. Confirm phase rotation, overload protection, piping alignment, and system curve before installation.

The close-coupled 1611E3E1 uses a cast-iron casing, one-piece cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic-face/EPT elastomer seal. Full-load current is listed as 2.0A or 1.0A, with 175 psi maximum pressure and a 40°F to 250°F fluid range. Sealed ball bearings require no routine lubrication, while external overload protection is required for the three-phase motor.

Key Features & Benefits

Why Choose Taco 1611E3E1 Three-Phase

This Taco 1600 Series pump provides published hydraulic, electrical, temperature, pressure, and dimensional data for closed-loop HVAC replacement work. Its 1/2 HP configuration suits systems needing more capacity than a smaller 1/3 HP circulator.

• Build: Cast iron, cast bronze, alloy steel, cupro-nickel, and ceramic/EPT components define the assembly.
• Value: Published operating data can reduce selection errors before a scheduled shutdown.
• Audience: Fits HVAC contractors, boiler technicians, facility engineers, and industrial maintenance teams.

Applications & Use Cases

Use this pump in industrial closed-loop heating and cooling systems within the listed 85 GPM and 40-foot limits. Check the 1-1/2-inch flange, 12-inch flange-to-flange length, pipe supports, valve clearance, motor access, and external overload arrangement. Keep fluid conditions between 40°F and 250°F and pressure below 175 psi.

Warranty & Support

• Warranty Terms: Warranty duration, coverage, exclusions, and registration requirements require confirmation from the authorized seller.
• Service Requirements: Confirm whether authorized service is required for warranty claims.
• Model Verification: Match Taco 1611E3E1, 1/2 HP, three-phase, and SKU 1611E3E1-1/2-3 to the order.

Verify voltage and phase rotation, align the flange, purge air, inspect strainers, and check for leaks during commissioning. Compare the running point with the actual pump curve before startup.
