Taco 1615E3E1 1/2HP 3PH 1600 Series In-Line Centrifugal Pump
The USA-made in-line centrifugal Taco 1615E3E1 uses a 1/2 HP ODP motor running at 1725 RPM to circulate 120 GPM through HVAC heating loops.
- 120 GPM volume clears boiler lines
- 38 feet head overcomes pipe drag
- 460V option connects to industrial panels
- Sealed ball bearings eliminate manual greasing
- 1.5 inch connections connect standard lines
Description
Move high-volume facility water with Taco 1615E3E1, a 1/2 HP three-phase close-coupled in-line centrifugal pump for closed-loop HVAC heating and cooling. Its 208–230/460 V motor, 120 GPM maximum flow, and 38 feet maximum head suit commercial secondary pumps where three-phase service is available. Confirm external overload protection, flange spacing, and system resistance before installation.
The 1725 RPM NEMA 56 ODP motor drives a one-piece cast-bronze impeller through an alloy-steel shaft with cupro-nickel sleeve. The ceramic face and EPT elastomer seal manage fluid at the shaft, while the pump carries a 175 psi pressure rating and 250°F maximum fluid temperature. Verify the 2.0 or 1.0 amp full-load current, 12-inch flange-to-flange length, and 50-pound dry weight before startup.
