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

Handle commercial secondary-loop circulation with Taco 1611E3E1 1/2 HP single-phase in-line centrifugal pump. Its 115 or 230-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 verify replacement fit. Confirm voltage, system curve, pipe alignment, and electrical protection before startup.

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 7.4A or 3.7A, with internal thermal overload protection. Maximum pressure is 175 psi, fluid temperature is 40°F to 250°F, and dry weight is 52 pounds. Sealed ball bearings require no routine lubrication.

Key Features & Benefits

• 1/2 HP Single-Phase Motor: Supports closed-loop hydronic and cooling systems using 115 or 230 volts.
• 85 GPM Maximum Flow: Provides a stated circulation reference for secondary-loop selection.
• 40 Feet Maximum Head: Helps compare system resistance and elevation requirements.
• 1-1/2-Inch Two-Bolt Flange: Supports replacement planning when the connection pattern matches.
• Internal Thermal Overload: Provides listed protection for the single-phase motor.
• 12-Inch Flange-to-Flange Length: Helps confirm piping-envelope compatibility.
• 52-Pound Dry Weight: Assists lifting and pipe-support planning.

Why Choose Taco 1611E3E1 Single-Phase

This Taco 1600 Series pump combines published hydraulic data with single-phase voltage flexibility. Its 1/2 HP motor and 1-1/2-inch flanged layout suit commercial secondary loops requiring more capacity than a smaller circulator.

• Build: Cast iron, cast bronze, alloy steel, cupro-nickel, and ceramic/EPT components define the assembly.
• Value: Sealed bearings and internal overload protection reduce routine service and wiring concerns.
• Audience: Fits HVAC contractors, boiler technicians, property managers, and facility maintenance teams.

Applications & Use Cases

Use this pump in closed-loop hydronic and cooling systems within the listed 85 GPM and 40-foot limits. Check the flange, 12-inch length, 52-pound handling requirement, pipe supports, valve clearance, and 40°F to 250°F fluid range. Confirm the actual pump curve before commissioning.

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, single-phase, and SKU 1611E3E1-1/2-1 to the order.

Verify 115 or 230-volt service, align the flange, purge air, inspect strainers, and check the seal area for leaks. Compare the operating point with the actual system curve.
