Century Centurion Pro HSQ165 1.65 HP Pool Pump Motor, 48Y Square Flange

The Century Centurion Pro HSQ165 is a 1.65 THP single-speed pool and spa pump motor engineered for demanding residential and light commercial applications. With a 48Y square-flange frame and dual-voltage 115/230V capability, this motor delivers reliable 3450 RPM performance and serves as a direct drop-in replacement for most 48Y frame pool pump motors.

🚩 PRO TIP

The HSQ165 is ideal for larger in-ground pools where higher flow rates are required. Before ordering, confirm your pump's frame size (48Y), shaft type (threaded stainless steel), and current voltage wiring. Upgrading from a 1.25 HP to a 1.65 HP motor can improve circulation in pools with longer plumbing runs or multiple returns.

FREQUENTLY ASKED QUESTIONS (FAQ)

Q: What pool pumps is the Century HSQ165 compatible with? A: This 48Y square-flange motor is a direct drop-in replacement for many popular pool pumps, including most Pentair WhisperFlo®, Pentair Challenger®, and standard Jandy® models that utilize a square flange. Always verify your current motor's frame (48Y) and flange type (Square Flange) before purchasing.

Q: Does this motor come with a replacement pump seal kit? A: No, this listing is for the replacement motor only. We highly recommend purchasing a new, pump-specific shaft seal kit (e.g., a WhisperFlo seal kit) whenever replacing a pool motor. Installing a new shaft seal prevents leaks and protects your new motor's bearings from water damage.

Q: Is the Century HSQ165 wired for 115V or 230V? A: The HSQ165 is a dual-voltage motor, meaning it can be wired for either 115V or 230V depending on your equipment pad's electrical setup. It is field-selectable upon installation, giving you maximum flexibility.
