Regal Rexnord b2235 Pool Pump Motor 4HP Dual Speed

Product Description

The REGAL REXNORD b2235 is a dual-speed pool pump motor rated at 4 HP high speed and 1/3 HP low speed, operating at 3450 RPM and 1725 RPM respectively on 230 volts. Built to a 56Y frame configuration, this motor is designed for residential and light commercial in-ground pool pump assemblies. Pool service professionals and licensed electricians install this unit as a direct drive replacement in standard pump housings. The dual-speed design supports energy-saving low-speed circulation alongside high-speed filtration and backwash cycles.

This motor fits in-ground pool pump systems that require a 56Y frame dual-speed motor. It is commonly installed in residential pool equipment pads where local energy codes mandate variable or dual-speed pump operation. The 230-volt single-phase power requirement is standard for dedicated pool pump circuits in residential settings. Pool technicians replacing failed single-speed or dual-speed motors in compatible 56Y frame pump housings will find this a straightforward swap.

Key Features

• Dual-speed operation: 4 HP at 3450 RPM for filtration and backwash, 1/3 HP at 1725 RPM for low-energy circulation
• 230-volt single-phase input matches standard dedicated pool pump circuits
• 56Y frame mounting for direct compatibility with common in-ground pool pump housings
• High-speed output supports full flow filtration, vacuuming, and backwash demands
• Low-speed mode reduces energy consumption during standard daily circulation cycles

Compatibility

Designed as an OEM-style replacement dual-speed pool pump motor for 56Y frame in-ground pool pump assemblies requiring 230-volt, 3450/1725 RPM dual-speed operation.

Installation Notes

Installation should be performed by a licensed electrician or qualified pool service professional in accordance with NEC Article 680 governing swimming pool electrical systems. Disconnect and lock out all power at the breaker before removing the existing motor or accessing the pump housing. Verify that the replacement motor shaft diameter and rotation direction match the existing pump impeller before completing the installation. Do not energize the motor dry; confirm the pump is primed and the volute is filled with water before startup.
