Hayward Variable Speed Pump Motor Drive for TriStar VS Pumps | SPX3400DR

Description

The Hayward Variable Speed Pump Motor Drive (SPX3400DR) is the OEM replacement motor drive for the TriStar VS variable speed pool pump line. Mounted to the top of the pump, this drive unit houses the full programmer interface and delivers direct-to-motor variable speed control.

The SPX3400DR features a fully rotatable keypad that allows programming flexibility regardless of equipment pad orientation. The interface includes four individual speed buttons, a navigation pad with center menu button, a Stop/Resume button, and a Quick Clean button — providing complete on-pump scheduling and speed control without a separate controller.

Specifications

Fits Into

Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Poolaroo Pro Tip

Before replacing the drive unit, confirm the pump motor itself is functioning correctly. The SPX3400DR addresses control and programming failures — if the motor is not spinning at all speeds or is drawing abnormal current, a motor fault rather than a drive fault may be the root cause. Have a qualified pool technician diagnose the fault before ordering this replacement.
