Taco 1612D Stainless Steel In-Line Pump 1/2HP 3PH 1.5″ Flange

Handle industrial potable-water circulation with Taco 1612D 1/2 HP three-phase in-line centrifugal pump for commercial hot-water systems. Its stainless steel casing, NSF-certified construction, one-piece cast-bronze impeller, and 1-1/2-inch two-bolt flange support material-focused replacement work. The pump reaches 95 GPM and 44 feet of head, with a 175 psi pressure limit. Confirm overload protection, phase rotation, flange dimensions, and system curve before installation.

The close-coupled 1600 Series pump uses a high-efficiency ODP motor running at 1,725 RPM, with an alloy-steel shaft and cupro-nickel sleeve. Its ceramic-face/EPT elastomer seal, stainless steel casing, and cast-bronze impeller are specified for industrial potable hot-water systems. The motor operates at 208–230/460 volts and draws 2.0A or 1.0A. The supplied data also lists 46 feet shut-off head, 12-inch flange-to-flange length, 50 pounds dry weight, 250°F maximum fluid temperature, external overload protection, and NSF/ANSI 372, UL, and CSA compliance.

Why Choose Taco 1612D

The Taco 1612D combines stainless steel construction with published flow, head, temperature, connection, and electrical data. It is a strong comparison option for commercial potable-water systems where three-phase power and a 1-1/2-inch flanged layout are available.

- Build: Stainless steel, cast bronze, alloy steel, cupro-nickel, and ceramic/EPT components define the supplied assembly.
- Value: Published hydraulic and electrical data helps reduce selection errors before a planned system shutdown.
- Audience: Suits plumbing contractors, hospital engineers, hotel maintenance teams, and industrial water-system buyers.

Applications & Use Cases

Use this pump in industrial potable hot-water systems that operate within the stated 95 GPM, 44-foot head, 175 psi, and 40°F to 250°F limits. Verify the 1-1/2-inch flange pattern, 12-inch flange-to-flange length, 50-pound handling requirement, pipe supports, and external overload arrangement. Check water-system compliance requirements 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 before purchase.
- Model Verification: Match Taco 1612D, 1/2 HP, three-phase configuration, and SKU 1612D-3 to the seller’s order documentation.

Verify voltage, phase rotation, and external overload protection before wiring. Inspect the flange gaskets, align the piping, purge air, clean strainers, and check the ceramic seal area for leaks during startup. Select the operating point from the system curve rather than shut-off head.
