Details

Nidec and US Motors motors are trusted for dependable replacement service across a wide range of pool applications, and this 2.25 total horsepower model uses the NPTQ225 reference with a 9.5 amp draw and 48Y square-flange configuration. A motor in the Nidec US Motors family is especially valuable when preserving original frame compatibility is critical to a successful repair.

This motor has practical value because the 48Y square-flange design is one of the key physical details that determines proper fit in many pump systems. Matching the correct THP rating, amperage, and flange style helps support a more predictable installation and protects the usability of the existing equipment.

This type of motor is especially useful when the failed motor is the primary issue and the surrounding pump assembly remains worth keeping in place. That makes motor replacement a more focused and efficient alternative to replacing broader system components.

Installed in the proper application, this Nidec US Motors motor helps support dependable operation, accurate fitment, and stronger long-term service confidence.
