The US Motors ASB843 is a genuine OEM pool-and-spa replacement motor, rated at 2 HP and built in a 56Y frame square-flange configuration. Designed for direct drop-in compatibility with many inground pool pump systems, this rugged motor delivers reliable full-rated performance.


Key Features

  • 2 HP, 3450 RPM, 208-230 V single-phase service-rated motor. 

  • Square-flange (SF) mounting style, 56Y frame size for direct replacement of many older pool pump motors. 

  • Service factor approximately 1.30; automatic overload protection included.

  • Non-reversible direction (CCW when facing shaft). 

  • Stainless steel shaft (5/8″ diameter threaded) with durable ball bearings. 

  • Open Drip Proof (ODP) enclosure. 

  • Suitable as replacement for many pool pumps originally equipped with 2 HP motors and square-flange mounting. 


Product Overview
For pool service professionals and equipment retailers, the ASB843 motor represents a high-value replacement for square-flange pool pump systems where the original motor has failed or is nearing end-of-life. Its full-rated 2 HP output ensures that flow and performance match original equipment specifications, reducing the risk of under-powering the pump and compromising circulation.

Installation is straightforward in systems with matching square-flange mounting: remove the old motor, transfer the mechanical seal (if still good) or install a new one, align the shaft, connect wiring as per original configuration, and secure the motor. Because this is a single-speed, full-rated motor, it is best suited for systems where a variable-speed upgrade is not required or where local code permits. Note: Some states (e.g., California, New York) now require variable-speed motors for pool pump replacements under certain conditions — confirm local code before selection. 

From a retail listing perspective, this motor should appear under “Pool Pump Replacement Motors – Square-Flange 56Y Frame” and highlight its compatibility (“Fits square-flange 2 HP pool pumps”), its OEM manufacturer origin (US Motors/Nidec), and key specs (2 HP, 3450 RPM, 208-230V, 56Y, SF).
