Product Overview

The U.S. Motors ASB848 AQUA-SHIELD Pool and Spa Pump Motor is a single-speed replacement motor designed for compatible pumps requiring a 1 HP full-rated motor, 56Y square-flange frame, and threaded shaft.

This motor operates at 3450 RPM and can be configured for either 115V or 230V, single-phase power. Its 1.65 service factor provides a total horsepower rating of 1.65 THP, allowing it to replace compatible full-rated and up-rated motors when all electrical and mechanical specifications match.

The ASB848 features a switchless AQUA-SHIELD design, threaded stainless-steel shaft, sealed ball bearings, automatic-reset thermal protection, continuous-duty construction, and an open drip-proof enclosure. A new mechanical shaft seal should always be installed when replacing the motor.
