Pentair | 011056 | 3HP IntelliFlo VSF Variable Speed and Flow Pool Pump

The Pentair 011056 IntelliFlo VSF Variable Speed and Flow Pool Pump combines eight programmable speeds with true flow control, so the pump holds a set flow rate instead of a set speed. It runs near-silently at low speeds and integrates fully with Pentair automation. Note that this model has been discontinued by Pentair and the recommended replacement is the IntelliFlo3 VSF.

Key Features

• Exceptionally quiet: at low speeds the pump is close to silent
• Advanced flow control: adjusts automatically to maintain a pre-programmed flow rate as conditions change
• Eight programmable speeds and a built-in timer for tailored schedules and energy savings
• Rotatable keypad with simplified menus; optional wall mount kit sold separately
• Top-mounted field wiring compartment for quicker installation and service access
• Totally enclosed fan-cooled (TEFC) motor for quiet, long-lived operation
• Cruise control holds system flow despite changing plumbing or environmental conditions
• Automation ready: full Pentair automation compatibility for remote control
• WEF rating 6.9, 3.95 THP for substantial savings over single-speed pumps

Frequently Asked Questions

What is the difference between variable speed and variable flow?

A variable speed pump holds the RPM you set. A variable flow pump like the IntelliFlo VSF holds the gallons per minute you set, and adjusts RPM on its own as the filter loads up or conditions change. That means your flow rate stays consistent between cleanings instead of drifting down.

This model is discontinued. Should I buy it anyway?

It depends on your situation. If you are replacing one IntelliFlo VSF in a system already built around it, keeping the same model avoids re-plumbing and re-configuring. If you are starting fresh, the IntelliFlo3 VSF is the current model and will have longer parts availability.

What does the WEF rating of 6.9 mean?

Water Efficiency Factor measures how many gallons a pump moves per watt-hour. Higher is better. At 6.9 the IntelliFlo VSF sits well above single-speed pumps, which is why variable speed pumps typically pay back their price difference through lower electricity bills.

Is 3.95 THP too much pump for my pool?

Not usually, because a variable speed pump rarely runs at full output. Most owners filter at low RPM for most of the day and only call on full power for spa jets, water features or vacuuming. The higher ceiling gives you headroom without forcing you to use it.

Do I need Pentair automation to use it?

No. The onboard rotatable keypad and built-in timer handle speeds and scheduling on their own. Automation adds remote control from a phone and coordination with heaters, lights and valves, but the pump is fully functional without it.

How quiet is it in practice?

At low filtering speeds most owners report it is hard to tell the pump is running from a few feet away. Noise rises with RPM, so a pump running high for a water feature will be clearly audible.

Does it come with a wall mount kit?

No. The keypad is mounted on the pump and rotates for viewing angle. The remote wall mount kit is a separate accessory if you want the controls somewhere more convenient.

Will it work with my existing plumbing?

In most retrofits, yes, though union and pad positions vary between pump families. Measure your suction and discharge centerlines and pad footprint before ordering, or send us a photo of your current installation and we will check it.
