Hardware Physical Specifications: Model: UST1152 Replacement Pool Motor Horsepower: 1.5 HP (Up-Rated) Frame Size: 56J (Round Flange / C-Face) Mounting Type: 4-Bolt Circular Face Mounting Shaft Type: 303 Stainless Steel Threaded Shaft (1/2-20 UNF-2A) Electrical & Performance Matrix: Voltage: 115V / 230V (Dual Voltage Adjustable) Service Factor (SF): 1.1 Speed: 3450 RPM (Single Speed) Frequency: 60Hz / Phase: Single Phase Technical Restoration Characteristics: This motor addresses common pump failures such as bearing noise, motor seizure, or electrical humming. By restoring the precise mechanical energy transfer to the pump impeller, it ensures the circulation system maintains the structural integrity of the filtration cycle specified by the pump manufacturer. Mandatory Installation Advisory: Before integration, verify the voltage setting on the motor's rear terminal board matches your local supply. Important: A new Shaft Seal (Pump Seal) must be installed simultaneously with the motor to prevent water intrusion into the bearings—reusing an old seal will lead to premature failure. This motor is NOT compatible with pumps requiring a square flange (56Y frame). Cross-Reference OE List: UST1152, ST1152, B229, EB229, C48L2N134A1, C48L2N134, K48L2N134, 168095, 177019
