🎯 Real World Examples & Applications
🏊♂ Residential In-Ground Swimming Pools
The SFP220-VS is purpose-built for residential in-ground pools and covers over 90% of typical home pool setups. With a maximum flow of 136 GPM (~8,160 GPH), it can handle pools up to approximately 40,000 gallons with ease. Run at low speed for 8–12 hours daily for efficient filtration, then boost to high speed for vacuuming or backwashing your filter. The 42 dB low-speed operation means you can run it overnight without disturbing anyone.🔄 Upgrading from a Single-Speed or Two-Speed Pump
If you’re replacing an aging Pentair SuperFlo, Hayward Super Pump, or any traditional single-speed pump, the SFP220-VS is engineered as a direct drop-in replacement. It shares the same plumbing footprint as the Pentair SuperFlo series (SF-N), includes both 1.5″ and 2″ fittings, and accepts your existing wiring (115V or 230V). Most homeowners complete the swap in under an hour. With the DOE now requiring variable-speed technology for new or replacement pool pump installations (effective July 19, 2021), this is a compliant, budget-friendly upgrade path.
🌊 Water Features & Fountains
Running waterfalls, spillovers, or deck jets? The variable-speed motor lets you program a dedicated higher speed just for your water features, then drop back to low speed for regular filtration. Unlike a single-speed pump that blasts at full power constantly, you can fine-tune the exact flow to make your water features look and sound their best — while still keeping energy costs low.
🏢 Small Commercial Pools & Community Facilities
With its robust 2.2 THP rating, durable ECM motor, and Energy Star certification, the SFP220-VS is a strong choice for small commercial installations including community pools, HOA pools, hotel pools, and resort spas. The programmable timer handles automated scheduling, and RS485 automation compatibility means it integrates with existing Pentair, Jandy, or Hayward commercial control systems.
☀ Seasonal Pool Openings & Closings
The self-priming design makes spring startups simple — the pump can draw water from up to 9.8 feet below the pump centerline without manual priming assistance. For seasonal pool owners, the programmable schedule lets you adjust run times as the weather changes: longer runs during peak summer heat, shorter runs during shoulder seasons.
