Hayward SPX3210Z2MER Pump Motor - 1-1/2 HP Square Flange 2-Speed Max-Rated

What This Part Is Used For
The Hayward SPX3210Z2MER is a pump motor listed as 1-1/2 HP, square flange, 2-speed, max-rated. It replaces the motor on a compatible Hayward pump so the system can operate on high speed for vacuuming and backwashing and low speed for routine filtration. This motor mounts to the pump wet end at the equipment pad.

Why This Part Matters
When a motor fails, circulation stops and the pool can turn quickly, especially during peak season. Two-speed systems also depend on proper speed switching for stable flow through heaters, filters, and cleaners. Replacing the correct motor restores reliable performance and predictable operation across both speeds. This is commonly needed when bearing noise, overheating, or breaker trips show the motor is at end of life.
