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

Distribute small-system HVAC water with Taco 1611E3E1 1600 Series in-line centrifugal pump for three-phase commercial heating applications. Its 1/3 HP motor operates at 208–230 or 460 volts, runs at 1,725 RPM, and provides up to 65 GPM with 32 feet of head. The 1-1/2-inch two-bolt flange and 12-inch flange-to-flange length help contractors check replacement fit. Confirm the system curve, phase rotation, overload protection, and piping alignment before installation.

The close-coupled 1611E3E1 uses a cast-iron ASTM A48 Class 30 casing, trimmed cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic-face/EPT elastomer mechanical seal. Its three-phase motor draws 1.4A or 0.7A at the listed voltage points. Maximum operating pressure is 175 psi, and fluid temperature ranges from 40°F to 250°F. The pump includes sealed ball bearings, while external overload protection is required for the motor circuit.

Key Features & Benefits

• 1/3 HP Three-Phase Motor: Fits small industrial HVAC systems with verified 208–230/460-volt service.
• 65 GPM Maximum Flow: Provides a stated capacity reference for commercial heating-system selection.
• 32 Feet Maximum Head: Helps contractors compare system resistance and elevation requirements.
• 1-1/2-Inch Two-Bolt Flange: Supports replacement planning when the existing connection pattern matches.
• 1,725 RPM Operation: Gives technicians a defined motor-speed reference for equipment comparison.
• External Overload Required: Reminds installers to include suitable motor protection in the control package.
• 12-Inch Flange-to-Flange Length: Helps verify the available piping envelope before shutdown.
• 46-Pound Dry Weight: Assists handling, lifting, and pipe-support planning during installation.

Why Choose Taco 1611E3E1 Three-Phase

The Taco 1611E3E1 provides a compact three-phase circulator with published hydraulic, electrical, temperature, and dimensional data. Its trimmed impeller is matched to the 1/3 HP configuration, giving contractors a defined option for smaller industrial HVAC systems.

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

Applications & Use Cases

Use this pump in small industrial HVAC and commercial three-phase heating systems within the listed 65 GPM and 32-foot limits. Check the 1-1/2-inch flange pattern, 12-inch flange-to-flange length, pipe supports, valve clearance, motor access, and external overload arrangement. Keep fluid conditions within 40°F to 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 before purchase.
• Model Verification: Match Taco 1611E3E1, 1/3 HP, three-phase configuration, and SKU 1611E3E1-1/3-3 to the seller’s order documentation.

Verify voltage, phase rotation, and external overload protection before wiring. Align the flange, purge air, inspect strainers, and check for leaks during commissioning. Compare the running point with the trimmed pump curve rather than the shut-off value.
