TJHSM 1 HP Pool Motor USQ1102 — 48Y Square Flange, 3450 RPM Quiet Outdoor Replacement

The TJHSM USQ1102 is a 1 HP, 48Y-frame square-flange pool motor built for reliable, quiet outdoor pumping and straightforward replacement installations.

This heavy-duty up-rated motor is designed for swimming pool filter and pump applications where dependable flow, simple mounting and long service life matter. The USQ1102 pairs a compact square-flange footprint with a 1 horsepower rated output and a 3450 RPM service-factor rating, giving you the torque and rotational speed needed to drive many standard pool pump housings. Constructed from corrosion-resistant materials, it’s intended for outdoor pool equipment areas and replacement scenarios where compatibility and noise reduction are priorities.

Will the USQ1102 fit my existing pool pump mounting?

In most retrofit or replacement cases the square flange and 48Y frame match common industry mounts. Measure your existing motor’s flange bolt pattern and shaft dimensions to confirm compatibility before ordering. This motor is aimed at direct-fit swaps for many popular filter and pump models.

• 48Y frame with square flange for standard pump housings
• Shaft dimensions and bolt pattern compatible with many OEM pumps
• Compact form factor to fit typical pool equipment compartments
• Up-rated 1 HP output to meet common filtration flow requirements

How loud is the TJHSM USQ1102 during operation?

The USQ1102 is engineered for smoother, quieter operation than older or undersized motors, reducing audible vibration and hum near pool equipment pads. Improved balance and quality bearings help cut noise during steady-state running. While not silent, it minimizes distraction and can be combined with vibration mounts for even lower sound transfer.

• Precision-balanced rotor reduces vibration and hum
• Quality bearings for quieter continuous operation
• Suitable for backyard installations where noise matters
• Can be paired with vibration isolators for further noise reduction

What performance can I expect from a 1 HP, 3450 RPM pool motor?

A 1 horsepower motor running at 3450 RPM supplies the torque and speed many single-speed pool pumps require for effective filtration and circulation. It supports typical residential pool plumbing and filter elements, allowing the pump to maintain proper turnover rates when matched with an appropriate impeller and housing. Performance will depend on pump model, plumbing layout and head pressure.

• 1 HP rating for standard residential pool circulation
• 3450 RPM service factor for consistent pump speed
• Delivers sufficient torque for most filter/impeller pairings
• Best results when matched to your pump’s hydraulic curve

How durable is this motor for outdoor pool environments?

The TJHSM USQ1102 uses corrosion-resistant materials and a robust housing to withstand the humid, chemically active atmosphere near pools. Sealing and protective finishes limit moisture ingress and surface corrosion, extending service life compared with untreated motors. Regular maintenance and proper enclosure placement will maximize longevity.

• Rust-resistant housing and finishes for outdoor durability
• Designed to tolerate pool-area humidity and splash exposure
• Quality internal components aimed at longer service intervals
• Easy-to-source replacement parts and support from TJHSM

Who is this for: The TJHSM USQ1102 is suited for homeowners, pool service technicians and contractors needing a reliable, straightforward replacement motor for residential swimming pool pumps. It’s a good match when you need a 48Y-frame, square-flange 1 HP motor that balances quiet operation with durable outdoor performance. Confirm mechanical and electrical compatibility with your pump model and wiring setup before purchase to ensure a proper and safe installation.
