This pump is so much smaller, more powerful, and quieter that the Jandy that it replaced. I had to slightly reconfigure the plumbing but that was easy enough. I like the fact that it has 4 programmable speeds and the pump itself is programmable with different start times and speeds which eliminates the need for unreliable Intermatic timers.

Best of the Best
I am a long time customer of Discount Pool. Bought this pump and it was shipped quickly. Used it less then a month and it has already saved me considerable dollars in electricity. When I first applied power I had to double check to make sure it was turned on because it is so quite. Highly recommend this pump.

Very quiet
I replaced a Pentair Challenger with minimal work (I put a paver under the new pump so that the inlet lined up with the old union). Used the old wiring in the conduit and I got it all in after about two hours (this old guy is a little slow on the up take). It blew me out of the water how quiet it was, and I like that I can see the watts it uses. I sat there and played with it to see how low I could get it (82 watts!).

Q: This pump requires a 4 prong 240V circuit?

Asked by: Matthew Greener - 9/24/2018
A: The pump accommodates a three-wire connection from the house panel. In addition to this, the grounding lug is provided for a bare wire connection to the local ground at the pool equipment pad.

Q: Do you have a pump that works on clorinated pools?

Asked by: Roger Ellis Emery - 3/6/2021
A: All pumps we carry work on pools with traditional chlorination or with saltwater chlorination, they are a great way to save a lot on energy. If you don't already have a salt chlorine generator (what make it a "salt pool"), we have some models you can add in as little as 15 minutes. A salt chlorine generator can save up to 40% or more on traditional chlorine costs, and makes things easier and the water nicer.

Q: Does this pump have a set of auxiliary contacts? I have a 400,000BTU gas heater that requires a certain amount of flow across the heat exchanger to operate safely and efficiently. If not, can you offer a simple solution to that requirement? I currently have a 2.5HP 2 speed pump running through a timer, a pair speed dip switches, and a pair of relays (Blue Haven control panel). There's 1 relay for each speed. The high speed control circuit interlocks with the heater. Thanks.

Asked by: Gary - 4/27/2021
A: There are no external relays on this pump. There is an available interface kit for it to be able to be controlled by an external relay.

Q: Does this have a relay for a Salt Water Generator?

Asked by: NotAPoolBoy - 3/18/2019

Q: I am using with a Pentair 520 Cartridge Filter. I would like to increase the water flo return in my pool which is 40,000 gallons, but was afraid the Pentair 520 cartridge filter could not handle the additional water flow?

Asked by: Bill Gordon - 7/29/2019
A: Looking at the manufacturer specs, that filter has a max recommended flow rate of 150 gallons per minute, which for the typical pool should be able to handle the pump flow at high RPM. Plus one of the benefits of variable speed pumps is that you get better filtration during the pump's low RPM operation, which is the majority of the time.

Q: I'm looking to replace a Pentair 340039 Superflow. Will this fit/align or will I need to do additional plumbing?

Asked by: Cullen Davis - 4/29/2022
A: The inlet to this pump is roughly 1.5" taller than the inlet of the Superflo, so you would need to plumb for that difference.

Q: If I connect this to an external timer, will this start self priming when power is connected? Also can you set the default speed it will then lower itself too automatically? It needs to retain this setting since external timer will disconnect power.

Asked by: Morrolan - 11/17/2019
A: All variable speed pumps are intended to be directly connected to power so that the built-in controller controls when and how it works. You can absolutely set the default speeds and when they get lowered/raised, though it does come ready out-of-the-box with energy-effecient programming that works for most people. Every time it starts at the high speed to ensure priming. If you call us at 866-766-5243 we can help walk you through any other questions.

Designed for Outdoor Installation and Operation

Traditional pumps operate at set, unchangeable speeds. Those speeds are almost always higher than required. As a result, they overpower the jobs they’re assigned to do, which wastes energy. The SmartFlo pump allows custom programming of optimum pump speeds for specific tasks such as filtering, heating, cleaning, spa jets and waterfalls. For virtually all applications, the optimum speed is lower than the preset, unchangeable speeds of older pumps. When water moves more slowly for longer periods, it helps reduce the occurrence of algae that forms more easily when water is pumped briskly and then allowed to rest for long intervals. Your filter works more effectively because it has more time to sift out particles from the water, and because particles aren’t forced through the filter media under needlessly high pressure. Automatic chemical dispensers and chlorinators also work better when water is kept moving.

Typical pump sizing would be for pools ranging from: 15,000 - 50,000 gallons

Please consult a professional to ensure proper pump sizing. A pump's capacity should ensure 1-2 circulation "turnovers" of the water in the pool through the filter each day. Pools with water features & pressure-dependent equipment may require greater pump capacity. Properly sized variable-speed pumps typically have more total horsepower than the corresponding single-speed pump.
