Run a three-phase commercial loop with Taco 1614E, a 3/4 HP close-coupled in-line centrifugal pump rated for up to 110 GPM and 50 feet of head. Its 1-1/2-inch two-bolt flange and 208–230/460 V motor suit larger HVAC systems where the electrical service and piping layout are already configured for three-phase operation. Confirm the duty point before installation.

The 1725 RPM NEMA 56 ODP motor uses a cast-iron body, one-piece cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic face with EPT elastomer seal. The pump carries a 175 psi maximum pressure rating, 12-inch flange-to-flange length, and 54-pound dry weight. Verify the 2.8 or 1.4 amp full-load current and external overload requirement before startup.

Key Features & Benefits

Why Choose Taco 1614E 3-Phase

The Taco 1614E offers useful flow, head, electrical, pressure, and dimensional data for commercial HVAC systems that require three-phase service.

- Build: Cast iron, cast bronze impeller, cupro-nickel shaft sleeve, ceramic seal face, and ODP motor define the pump.
- Value: Detailed operating and handling data can simplify replacement planning and field coordination.
- Audience: Suited to commercial HVAC contractors, boiler technicians, facility engineers, and industrial maintenance teams.

Applications & Use Cases

Use Taco 1614E for closed-loop commercial HVAC, large boiler branches, chiller loops, and compatible 1-1/2-inch flanged systems. The pump has a 12-inch flange-to-flange length and weighs 54 pounds dry, with 110 GPM maximum flow and 50 feet maximum head. Verify supports, valves, flow direction, and motor clearance before installation.

Warranty & Support

- Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with Taco or the seller.
- Match model 1614E, 3/4 HP motor, three-phase voltage, full-load current, flange size, and overload requirement before ordering.

Flush and fill the loop, purge trapped air, inspect the seal and flange gaskets, and verify phase rotation before startup. Confirm external overload protection, then monitor flow, pressure, vibration, temperature, and leakage during commissioning.
