Product Overview

The U.S. Motors Neptune 2.7 HP Variable Speed Square Flange Motor, 48Y, 230V | NPTQ270 is a 2.7 total HP variable speed replacement pool pump motor from Nidec with a 48Y square flange mount.

The motor, drive and keypad are built into one unit. It runs from 600 to 3450 RPM on 230V single-phase power, and it can be programmed with its own schedules or connected to a pool automation system.

Ideal For

Upgrading a single-speed square flange pump to variable speed

48Y square flange pumps such as Pentair SuperFlo and WhisperFlo and Jandy Stealth and PlusHP

Pool service techs replacing motors on existing wet ends

Key Features

2.7 total HP, variable speed, 600-3450 RPM

48Y square flange mount

230V single phase, 11.1 SF amps

TEFC, IPX5 finned aluminum enclosure

Built-in backlit keypad with up to 7 daily schedules, adjustable priming and freeze protection

Modbus RTU (RS-485) and low-voltage connections for pool controllers, plus an auxiliary relay

Benefits

Running at lower speeds for daily filtration uses much less power than a single-speed motor and is quieter at the equipment pad.

Swapping only the motor keeps a good wet end in service, so you can move to variable speed for less than the cost of a new pump.

Specifications

Warranty & Compatibility

This motor fits pumps built for a 48Y square flange motor. It does not fit round-flange 56J C-face pumps. Check your current motor's nameplate and pump model before ordering; the 56J version is the Neptune NPTT270. Replace the shaft seal whenever the motor is changed.

The motor requires 230V power and should be installed and wired by a qualified electrician or pool technician. Warranty length varies by seller listing; see Nidec's warranty terms.
