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).
