Pentair IntelliFlo VSF vs. IntelliFlo3 VSF: Should You Still Buy the Older Pump? (011056 vs 011075)
Pentair sells two 3HP variable speed and flow pumps that look almost identical on a spec sheet. The IntelliFlo VSF (model 011056) is the older design that has been sitting on pool pads for years. The IntelliFlo3 VSF (model 011075) is the newer platform that replaced it. Customers call us all the time asking which one to buy, so here is the honest breakdown.
What's the difference between the IntelliFlo VSF 011056 and the IntelliFlo3?
Same horsepower, different generation. Both pumps are 3HP, both run on 230V, and both use Pentair's variable speed and flow technology, which means they can hold a target flow rate instead of just a fixed motor speed.
The real differences are in the drive and the controls. The 011056 uses the classic IntelliFlo drive and keypad that Pentair built for over a decade. The 011075 is a full redesign with a new drive, a simpler control pad, and app connectivity built in. Under the hood they move water about the same. It's everything around the wet end that changed.
Is the Pentair 011056 still worth buying?
Yes, but only in a couple of situations. The IntelliFlo VSF is a proven pump. It's quiet, it's efficient, and there are thousands of them running right now without a complaint.
The strongest case for the 011056 is a like-for-like replacement. If your automation system, plumbing, and schedules were all built around this exact pump and it finally gave out, dropping in the same model means zero reprogramming and zero surprises. Some service techs also just prefer the platform they have worked on for years, and that familiarity has real value when something needs troubleshooting later.
What does the IntelliFlo3 011075 do better?
The controls and the connectivity, mostly. The IntelliFlo3 has a cleaner interface right on top of the pump, and you can monitor and adjust it from your phone through the Pentair Home app. No more crouching behind the pump squinting at a small screen while you punch through menus.
- App control from your phone, which makes schedule changes painless
- A newer drive design, so replacement parts will stay available far longer
- Sensorless flow control carried over and refined from the VSF line
- An optional relay version (model 011076) if you want the pump to switch other equipment like a salt cell or a booster pump
That last point matters if you don't have full automation. The 011075 is the standard model, and the 011076 adds the I/O board. If you already own an automation panel, the 011075 is the one you want.
Will the IntelliFlo3 work with my existing automation?
In most cases, yes. The IntelliFlo3 is compatible with Pentair automation systems, including EasyTouch, IntelliTouch, and IntelliCenter, over the same communication wiring the old pump used. Older panels may need a firmware update to recognize the newer pump, so it's worth checking your system version before install day. The 011056 obviously works with those systems too, since they grew up together.
The price flip: why the newer pump costs less
Here is the part that surprises people. The older 011056 now sells for more than the newer 011075. As of this writing, the IntelliFlo VSF runs $2,499.00 in our store while the IntelliFlo3 VSF is $1,679.00.
That's not a typo. The old pump is winding down, supply is thin, and remaining units carry a premium. The IntelliFlo3 is the pump Pentair builds in volume now, so pricing is sharper. You're paying extra for the old platform, not getting a discount on it.
011056 vs 011075: which one should you buy?
For most pools, buy the IntelliFlo3 VSF 011075. It costs less, it's easier to live with, and parts support will outlast the older design by years. Choose the 011056 only if you need an exact match for an existing setup and the reprogramming or firmware questions are a dealbreaker for you.
Either way you're getting a quiet, efficient 3HP pump that will cut your power bill compared to a single speed unit. The 011075 just gets you there for less money.
