With a 2.6 THP variable-speed motor and WEF rating of 8.4, it meets the needs of modern in-ground pool systems seeking both strong flow capability and lower energy costs. Its drop-in compatibility with existing Pentair WhisperFlo infrastructure allows for straightforward upgrades. The TEFC motor and premium build ensure long-term durability, while the multi-speed programming adapts to filtration, heating, cleaning or spa demands.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eFirst program the pump’s lowest speed to meet your pool’s turnover requirement (filtration phase). Then use secondary speeds for cleaning or heating. By matching flow to task rather than always running high speed, you’ll realize significant energy savings. Consider complementing this pump with a variable-speed filter and integrating into your Pentair automation setup for full-system optimization.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eMount the pump on a stable, vibration-isolated equipment pad. Ensure wiring meets NEC\/local code and uses correct voltage. Minimize suction and discharge piping restrictions. Program the pump speeds according to your pool’s flow requirements rather than defaulting to max speed. Monitor initial wattage draw to confirm expected performance.\u003c\/p\u003e","brand":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","offers":[{"title":"Default Title","offer_id":62589888266611,"sku":"PUR-10-420","price":2060.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/2464\/4211\/files\/whisperflo_a6c9c5a5-105e-4838-b201-8784f99ab480.jpg?v=1772563730","url":"https:\/\/shop.cavanaughpool.com\/products\/pentair-whisperflo-vst-variable-speed-pool-pump-ec-011533","provider":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","version":"1.0","type":"link"}
