Taco TACO-MOT-D-104S Pro-fit Replacement Motor 1/2 Hp

Product Description

The TACO TACO-MOT-D-104S is a Pro-Fit replacement motor rated at 1/2 HP and designed for hydronic circulators and inline pump applications. Running on 115/230V single-phase power at 60 Hz, it spins at 1725 RPM with clockwise rotation on a 4-pole configuration. The motor features permanently lubricated bearings, eliminating the need for routine maintenance. A rigid steel mounting cradle with resilient motor mounts is included to simplify shaft alignment and reduce vibration during operation. Licensed HVAC and plumbing technicians install this motor as a direct replacement in heating system pump assemblies.

This motor is designed to replace Bell Gossett and Armstrong circulators and pump motors up to 3 HP in residential and light commercial hydronic heating systems. It is suitable for hot water heating loops, pressure-boosting applications, and similar pump-driven systems where an OEM motor has failed or reached end of service life. The steel cradle mount design accommodates easy field alignment without specialized tooling.

Key Features

• 1/2 HP output at 1725 RPM for standard hydronic circulator applications
• Dual-voltage capable: 115/230V single-phase, 60 Hz
• Clockwise rotation as viewed from the shaft end
• Permanently lubricated bearings — no routine maintenance required
• Rigid steel mounting cradle with resilient mounts for vibration-free, quiet operation
• Designed to replace Bell Gossett and Armstrong motors up to 3 HP

Compatibility

Designed as a Pro-Fit replacement for Bell Gossett and Armstrong pump motors up to 3 HP. Verify shaft diameter, frame size, and mounting configuration before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Shut down the hydronic system and disconnect electrical power at the breaker before removing the existing motor. Verify that the replacement motor rotation, voltage tap, and shaft alignment match system requirements before energizing. Wiring must comply with applicable NEC requirements for the installed voltage and circuit rating.
