Key Features

Typical Applications
Perfect as a replacement for worn out or failed pool pump motors when servicing sand, cartridge, or D.E. filters. Also suitable for upgrades where a higher-power motor is needed to maintain proper flow, especially in pools with larger plumbing, multiple returns, or high head-loss plumbing layouts.
Installation & Compatibility Notes
Before installation, switch off and lock out power, then drain and disconnect the pump housing. Remove the old motor and inspect shaft seal and wet-end components for wear. Mount the HSQ165 using the same bolt pattern and flange orientation. Re-wire to match supply voltage (115 or 230 V), reconnect plumbing, re-prime the system, and confirm normal pressure and flow. Always replace worn seals when installing a new motor.
Why Choose This Motor?
The HSQ165 offers proven reliability, strong performance, and wide compatibility — a trusted choice for professional pool service techs and DIY pool owners alike. Its robust build, simple wiring design and powerful output make it a dependable replacement for many standard pool pump motors.
Maintenance Tips
- Inspect shaft seal and wet-end fittings annually for leaks or wear.
- Ensure proper ventilation around the motor housing to avoid overheating.
- Flush debris from strainer basket regularly to reduce amp load and prolong motor life.
- If pool is idle long-term, store motor protected from weather and moisture.
