The Pentair WaterFall Specialty Pump Motor (Part Number 355222S) is a specific replacement motor designed for Pentair's WaterFall line of pool and spa pumps, particularly models AF-180, AFP-150, and AFP-180. These pumps are often used for creating dramatic water features like waterfalls, laminar jets, and sheer descents, which require specific flow characteristics.

Here's a detailed description of this motor:

Key Features and Specifications:

• Horsepower (HP): This motor is typically rated at 1 HP (Horsepower). While some listings might mistakenly show 1.5 HP, it's designed to drive the 1 HP output of the specified WaterFall pumps.
• Voltage: It is a dual-voltage motor, capable of operating on 115V or 230V single-phase electrical supply. This provides flexibility for installation in various residential or light commercial setups.
• Frame Size: It features a 56Y frame (often referred to as a "Y" frame), which is a specific motor frame size designed to ensure proper fit and alignment with the WaterFall pump housing.
• Phase: Single Phase (1PH), standard for residential and many commercial applications.
• Frequency: 60 Hz, the standard electrical frequency in North America.
• Specialty Design for Water Features: Unlike standard circulation pump motors, this motor is specifically engineered to provide the consistent, high-volume flow needed for impactful water features, ensuring smooth and visually appealing waterfalls or other effects.
• Durable Construction: Pentair replacement motors are built to withstand the demanding conditions of the pool and spa environment. They typically feature:
  • Sealed Ball Bearings: Often two sealed ball bearings with ample capacity for extended life, chosen for quiet operation and lubricated for life with greases resistant to moisture and heat.
  • Aluminum End Frames: Precisely machined for maximum concentricity and minimum runout, contributing to smooth and quiet operation.
  • Open Drip Proof (ODP) Enclosure: Designed to prevent falling moisture and solid objects from entering the motor, though it is intended for use in a covered or protected area.
• Direct Replacement: This motor is a genuine Pentair factory original replacement part, ensuring proper compatibility and performance when replacing an existing motor on the AF-180, AFP-150, or AFP-180 WaterFall pumps.
• Weight & Dimensions: It weighs approximately 35 pounds and has dimensions of approximately 22.5 inches length x 11.5 inches height x 9.25 inches width.

Purpose and Application:

The Pentair 355222S motor's primary purpose is to serve as the power source for Pentair's WaterFall specialty pumps. These pumps are distinct from standard circulation pumps as they are optimized for creating and maintaining decorative water features. If the motor on your AF-180, AFP-150, or AFP-180 pump is failing (e.g., humming, not starting, overheating), this 355222S motor is the direct replacement part to restore its functionality and ensure your water features operate as intended.

Important Considerations:

• Professional Installation Recommended: Due to the electrical connections and technical nature of pump motor replacement, professional installation by a qualified pool technician is highly recommended.
• Replace Shaft Seal: It is strongly advised to replace the pump's shaft seal (mechanical seal) whenever replacing the motor, as this often wears out concurrently with the motor and ensures a watertight connection.
• Verify Pump Model: Always double-check your specific Pentair WaterFall pump model to confirm that 355222S is the correct motor replacement.
