Product Overview
Restore control of your compatible variable-speed pool pump with the Hayward SPX3400DR Replacement Motor Drive. This genuine Hayward replacement component manages motor operation and speed settings, making it an important repair option when a qualified technician identifies a failed drive.
Designed for compatible EcoStar® and select TriStar® variable-speed pump configurations, the SPX3400DR allows the existing pump to be serviced without purchasing a complete replacement pump when its motor and hydraulic components remain in good condition.
The drive assembly features a digital control interface for convenient programming and operation. Adjustable speed settings help tailor circulation to daily filtration and higher-demand tasks, while operating information assists with system monitoring.
Important Compatibility Notice: SPX3400DR is the standard, non-SVRS replacement drive. Pumps equipped with a Safety Vacuum Release System require the correct SVRS-specific replacement. Confirm the pump model, serial number, existing drive number, and control configuration before ordering.

A similar-looking drive does not guarantee compatibility. Display connections, motor requirements, automation communication, and manufacturing revisions can affect replacement selection.
Installation and Repair Considerations
Before replacing the drive, have a qualified technician diagnose the problem. A pump that will not start may have a supply-voltage issue, wiring fault, motor failure, or mechanical obstruction rather than a defective drive.
Professional installation includes disconnecting power, checking electrical connections, maintaining grounding and bonding, and configuring the replacement for the existing equipment. Pump schedules and automation settings should be reviewed after installation.
Drive replacement does not increase the pump’s horsepower or repair damaged bearings, seals, impellers, or plumbing.
Frequently Asked Questions
Does SPX3400DR include the pump motor?
No. This product is the replacement drive assembly. The motor and complete pump are separate components.
Will it fit every Hayward TriStar variable-speed pump?
No. TriStar pumps have different drive generations and configurations. Verify the exact model and existing drive before purchasing.
Can I use it on an SVRS pump?
Do not substitute this standard drive for an SVRS-specific drive. The replacement must preserve the pump’s required safety functionality.
Will this fix a blank display or a pump that will not start?
It may resolve the issue when a failed drive is the confirmed cause. Professional diagnosis is recommended before ordering.
Will my existing automation work with the replacement?
Compatibility depends on the pump, controller, wiring, and configuration. Have your installer verify communication requirements.
