The Pentair IntelliFlo VSF (Variable Speed and Flow) pump is one of the most advanced pool pumps available. It allows precise control of water flow and speed, helping you save energy, maintain proper filtration, and run water features efficiently. But to get the best results, you need to understand how to set it up for your pool’s specific needs.
This guide covers recommended IntelliFlo VSF settings for filtration, heating, water features, and cleaning cycles, along with tips to maximize performance and efficiency.
Understanding How the IntelliFlo VSF Works
Unlike single-speed pumps, the IntelliFlo VSF can run at different RPMs (rotations per minute) or in GPM (gallons per minute) mode. Lower speeds save electricity and reduce noise, while higher speeds are used for vacuuming, spa jets, or backwashing. The VSF model keeps a constant flow rate regardless of filter pressure changes, which helps maintain consistent performance.
Recommended IntelliFlo VSF Settings
1. Daily Filtration
Goal: Keep water circulating enough to pass the entire pool volume through the filter once or twice per day.
Suggested setting:
- Flow Mode: 30–40 GPM (or 1,600–2,000 RPM)
- Run Time: 8–12 hours depending on pool size, bather load, and climate
Tip: Many pool owners run filtration longer at low speed for maximum energy savings.
2. Heating (Pool or Spa)
Goal: Provide enough water flow to meet the heater’s minimum GPM requirement.
Suggested setting:
- Check your heater’s manual for minimum flow—commonly 40–50 GPM.
- Adjust speed until heater stays on without cycling off.
- Typical RPM range: 2,600–3,100 RPM depending on plumbing and heater type.
3. Water Features (Sheer Descents, Bubblers, Deck Jets)
Goal: Run features at a visually pleasing flow while avoiding excessive energy use.
Suggested setting:
- Start around 2,800 RPM and adjust up or down to achieve desired appearance.
- If features splash excessively, reduce speed until the flow is smooth.
4. Vacuuming or Pressure-Side Cleaner
Goal: Provide enough flow for suction or booster pump operation.
Suggested setting:
- For suction cleaners: 2,600–3,100 RPM
- For booster pump: Set IntelliFlo to feed required flow (usually full speed at 3,450 RPM during cleaner cycles)
5. Backwashing or Filter Cleaning
Goal: Move enough water to flush debris from the filter effectively.
Suggested setting:
- 3,000–3,450 RPM for 2–3 minutes, or as specified by filter manufacturer
Programming Tips for Energy Savings
- Run longer at low speeds rather than shorter at high speeds—low RPMs draw much less power.
- Use multiple programs throughout the day for different needs (e.g., low-speed filtration plus a short high-speed cleaning cycle).
- Take advantage of the VSF mode to maintain constant GPM for heaters and water features.
- Keep skimmer performance in mind—very low RPM may reduce debris capture.
Sample IntelliFlo VSF Daily Schedule
This is just an example. Your exact schedule should be based on pool size, usage, and equipment.
- 8:00 AM – 2:00 PM: 1,800 RPM (Filtration) – 6 hours
- 2:00 PM – 4:00 PM: 2,800 RPM (Water Features) – 2 hours
- 4:00 PM – 6:00 PM: 3,000 RPM (Heater/Spa) – as needed
- 6:00 PM – 8:00 PM: 1,600 RPM (Evening Circulation) – 2 hours
When to Adjust Settings
- Seasonal changes—hotter weather or heavy pool use may require longer run times.
- After adding chemicals—run pump longer at moderate speed to circulate water thoroughly.
- After storms or heavy debris—short burst of high RPM helps clear water faster.
The IntelliFlo VSF’s strength is flexibility. By tailoring settings to your pool’s specific needs, you’ll get clean, clear water while saving significantly on energy costs compared to single-speed pumps.
