Motor Design & Construction
The SQ1072 features a precision-wound PSC design that eliminates the need for a starting capacitor while providing smooth, efficient motor starts and quiet operation. Ball bearings on both ends ensure long service life with minimal maintenance, even under continuous-duty pump loads. The threaded shaft is purpose-built for direct coupling to pump assemblies, simplifying installation and alignment.
Dual-Voltage Flexibility
Factory-wired for 115V operation with the ability to reconfigure for 230V service, the SQ1072 adapts to virtually any single-phase electrical supply. This flexibility reduces the need to stock multiple motor SKUs and makes the unit ideal for both new installations and field replacements.
Open Drip Proof Enclosure
The ODP enclosure allows for maximum airflow and motor cooling in environments where the motor is protected from direct water exposure. This design is well-suited for indoor mechanical rooms, boiler rooms, and equipment closets where ambient ventilation is available.
Typical Applications
- Hydronic circulating pumps
- In-line water pumps
- Booster pump systems
- HVAC chilled and hot water pump replacements
- General pump motor replacement applications
