It replaces the motor on a compatible Hayward pump so the circulation system can run on high speed for vacuuming and backwashing and low speed for daily filtration. This motor mounts to the pump wet end at the equipment pad.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e A failing motor can trip breakers, overheat, or stop starting, which leaves the pool without circulation and quickly impacts water clarity. Two-speed systems also rely on proper motor operation to balance flow and energy use, especially if a cleaner or heater is in the loop. Replacing the correct motor restores reliable run performance and predictable speed operation. This is a common fix when the wet end is still sound but the motor has failed from age, water exposure, or bearing wear.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManufacturer part number: SPX3220Z2MER\u003c\/li\u003e \u003cli\u003ePump motor\u003c\/li\u003e \u003cli\u003eHorsepower listed: 2-1\/2 HP\u003c\/li\u003e \u003cli\u003eFrame style listed: square flange\u003c\/li\u003e \u003cli\u003e2-speed motor, max-rated as listed\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Disconnect power at the breaker and verify wiring is de-energized before servicing the motor. Replace the shaft seal when swapping motors so the wet end does not leak onto the new motor. Confirm by manufacturer part number before ordering.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAbout the Hayward Brand\u003c\/strong\u003e\u003cbr\u003e Hayward manufactures a complete residential pool equipment ecosystem including pumps, filters, heaters, automation controls, cleaners, chlorination systems, and service parts. Their pumps integrate with Hayward filtration and heating equipment across many pool pads, making proper circulation essential for the full system. Replacement motors allow targeted repairs when the wet end is still in good condition. Hayward replacement parts are widely supported across the pool industry.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCommon Service Context\u003c\/strong\u003e\u003cbr\u003e Techs typically replace two-speed motors when a pump hums but won’t start, trips the breaker, or runs only on one speed. It is often identified after verifying the wet end spins freely and the motor shows overheating or bearing noise.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":52050178375954,"sku":"SPX3220Z2MER","price":849.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/2279\/1186\/files\/HPPSPX3220Z2MER_0.jpg?v=1771892431","url":"https:\/\/www.aquaterrabackyard.com\/products\/hayward-spx3220z2mer-pump-motor-2-1-2-hp-square-flange-2-speed-max-rated","provider":"Aqua Terra Backyard","version":"1.0","type":"link"}
