Product Overview
The Century Pool Pump Motor 3/4HP 1 Phase 60Hz 230/115V 56J | UST1072 is a single-speed, threaded-shaft replacement motor for pool pumps that use a 56J-frame motor. It runs at 3450 RPM on 115V or 230V single-phase power.
This open drip-proof motor has a capacitor-start design, sealed ball bearings and automatic-reset thermal overload protection. It is a common replacement for 3/4 HP Hayward pumps such as the Super Pump and Max-Flo.
Ideal For
Replacing a failed 3/4 HP 56J threaded-shaft pump motor
Hayward Super Pump, Max-Flo and similar 56J pumps
Systems wired for 115V or 230V single phase
Pool service technicians
Key Features
3/4 HP, single speed, 3450 RPM
56J frame with 5/8" threaded stainless steel shaft
Dual voltage 115/230V, single phase, 60 Hz
Capacitor start; automatic-reset thermal overload
Open drip-proof (ODP) enclosure; Class B insulation

Benefits
Replacing only the motor gets a pump back in service without buying a complete new pump, as long as the wet end is in good shape.
Dual-voltage wiring lets it match the existing supply, and thermal protection helps guard against overheating.

Warranty & Compatibility
Match the frame (56J), shaft type (threaded), horsepower, service factor and voltage on your old motor's nameplate before ordering. Compatible Hayward models listed by retailers include SP2605X7, SP3005X7AZ, SP2800X7 and PHPM.75.
New DOE rules require variable-speed motors for many replacement pool pump motors; Regal lists a September 2027 compliance date for this size class. Installation should follow local electrical code, and a licensed electrician is recommended. Warranty terms are set by the manufacturer.
