Taco 1615 1/2HP 1PH 1600 Series In-Line Centrifugal Pump

Taco 1615 1/2 HP circulates large volumes through closed-loop HVAC systems using a 1725 RPM single-phase motor. Its cast-iron body, 1-1/2-inch two-bolt flange, and 120 GPM maximum flow suit larger hydronic circuits where a small zone circulator may not provide enough capacity. Confirm the required head, flange spacing, and electrical connection before installation.

The close-coupled pump uses a NEMA 56 ODP motor, one-piece cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic face with EPT elastomer seal. It accepts 115 or 230 V power, draws 7.4 or 3.7 amps at full load, and carries a 175 psi pressure rating. Verify the 12-inch flange-to-flange length, 56-pound dry weight, and operating curve before startup.

Key Features & Benefits

Why Choose Taco 1615

The Taco 1615 is aimed at large-volume hydronic circulation where contractors need more flow capacity than a small residential circulator can provide, along with detailed electrical and dimensional references.

- Build: Cast iron, cast bronze impeller, cupro-nickel shaft sleeve, ceramic seal face, and ODP motor define the assembly.
- Value: The listed full-load current, dimensions, pressure, flow, and head simplify equipment comparison and replacement planning.
- Audience: Intended for commercial HVAC contractors, boiler technicians, facility engineers, and hydronic maintenance teams.

Applications & Use Cases

Use Taco 1615 for high-flow closed-loop HVAC, large hydronic headers, commercial boiler branches, and compatible 1-1/2-inch flanged systems. The pump has a 12-inch flange-to-flange length and 56-pound dry weight, with 115/230 V operation. Verify pipe support, valve access, motor clearance, flow direction, and service space before installation.

Warranty & Support

- Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with Taco or the seller.
- Match model 1615, horsepower, 115/230 V supply, full-load current, flange size, and pump curve before purchase.

Flush and fill the loop, purge trapped air, inspect the seal and flange gaskets, and verify the selected voltage before startup. Check operating flow, head, pressure, vibration, and temperature during commissioning.
