A.O. Smith B2852 0.75 HP Pool Motor
The A.O. Smith B2852 is a 3/4 HP pool motor designed for reliability with a 56Y frame and PSC/Odp enclosure. It runs at 3450 RPM on 230/115 volts, offering a balanced mix of power and efficiency for standard inground pool pumps. The stainless steel shaft helps reduce wear in demanding environments. This motor suits replacement projects where a traditional PSC design remains appropriate, and it aligns with common pool pump configurations.
Century B2854 1-1/2 HP Pool Motor
The Century B2854 delivers a higher horsepower option at 1.5 HP with 3450 RPM, suitable for larger or more demanding pool systems. It uses a 56Y PSC enclosure and supports both 230 and 115-volt configurations. The motor is designed to be a direct replacement for older Century models like the B854, providing compatibility with many existing pool pump setups while maintaining a robust service factor.
US Electric Motor AST165 – 1.5 HP
The US Electric Motor AST165 is a 1.5 HP pool pump motor rated for 115/230V operation at 3450 RPM with 60 Hz. It features a 56J frame and non-reversible (CCW) rotation, plus automatic overload protection and a service factor of 1.0. This motor is positioned as a reliable option for typical residential pool pumps where consistent performance is essential and energy use is balanced with output.
US Motors ASB844 3 HP Pool Motor
The ASB844 is a robust 3 HP pool motor rated at 3450 RPM with a 56Y frame and 208-230V capability. The motor’s high horsepower makes it suitable for larger or more demanding pool systems that require stronger pump performance to maintain water flow and filtration efficiency in larger residential installations or spa pools.
A.O. Smith ST1072 0.75 HP Pool Motor
The ST1072 from Century (A.O. Smith listed in catalog) offers a 0.75 HP rating with 3450 RPM and a 56J frame. It supports 230/115V operation and uses a capacitor start design for reliable startup. This motor is well suited for standard residential pools with medium run demands and aligns with common 56J frame pump configurations, providing a straightforward replacement option.
Buying Guide
Key considerations when choosing a pool motor include horsepower and flow needs, voltage compatibility, and physical fit like the frame and enclosure. For smaller to medium pools, 0.75 to 1.5 HP motors are typically sufficient, while larger installations may benefit from 2 HP or higher. Check whether you need a PSC (permanent split capacitor) design for efficiency or a capacitor start motor for strong start-up torque. Enclosures (ODP vs. TEFC) influence protection against moisture and outdoor exposure. Matching the frame (56Y, 56J) and shaft configuration to your existing pump is essential to ensure a proper fit and alignment. Consider warranty and manufacturer support for long-term reliability.
Performance expectations vary by region and pool size. In many residential setups, a 3450 RPM, 60 Hz design balances speed with energy use and quiet operation. If you have a larger pool or a high head loss due to filters, the higher horsepower options may maintain flow more effectively. Always verify electrical requirements, including available voltage (115V vs 230V) and circuit capacity. Accessibility for replacement and ease of installation are practical factors, as are availability of spare parts like capacitors and seals.
