Pentair 340039 SuperFlo Pool Pump Review

Pentair 340039 SuperFlo Pool Pump ReviewPentair had brought up a number of pool pumps over time. There are both high-powered ones that are dedicated to pumping large pools. And there are as small as less than 1HP motor pumps as well.

Today, we have been able to put our hands on a Pentair model that comes with 6 power diversity. Starting from ¾ horsepower, there are versions as powerful as 1-1/2 horsepower. And all of them come under the domain of Pentair 340039.

We know that this Pentair 340039 isn’t the most powerful pool pump that the brand makes. But we are specifically addressing the low-end range of pool pumps.

Therefore, let’s jump right into this Pentair 340039 SuperFlo High-Performance Single Speed Pool Pump review and check out if it’s worth your time and money or not-

 Another pool pump from Pentair

Features and Benefits

A Certified, Strong Built Quality

The first selling point of this pool pump is its durable construction powered by the 40 years of brand experience of Pentair. The motor, being the heart of the pump, possesses this specifically built quality.

Due to the high service factor and 56 square flange motor built quality, you can literally avail a commercial-grade pump motor at the price of consumer-grade one.

Superior Internal Waterflow Inducing Silent Operation

As long as it’s about a pool pump from Pentair, we’ve seen them concerned to keep it noise-free, as much as possible. And the Pentair 340039 is no different.

With the superior internal water flow design, the operation remained to be quite silent. Especially the hydraulic noise that bothers often, is kept low with this mechanism.

Easy to inspect Strainer Basket

The strainer basket, being a compulsory part of a pool pump, is needed to be cleaned once in a while. To know when is the time to do so, there is a transparent, clear lid provided in this model.

With that, you don’t have to keep anxious about when to clean the strainer basket up all the time. All you have to do is to have a glimpse through the transparent lid and you’re informed.


Ready for Both Voltage Environment

There are models available that connect to either 115V outlets or 220V outlets. But as we have said earlier, there are a handful of versions of Pentair 340039 that come with the voltage diversity.

There are models within this array that suit 115V outlets, and there are models that connect to 220V ones. Based on where you’re supposed to use this pump, you have to select the one you need.


Low Maintenance Required

We have talked about emptying the restrainer basket earlier, which happens to be one of the core maintenance tasks. Another maintenance scheme is priming the motor, which almost keeps you on your edge if your pool doesn’t come with a motor that self-primes itself.

The good news is, the Pentair 340039 comes up with a self-priming motor. So, no need to worry about that.

A Higher Return of Your Pump Investment

The motor that comes within the pump is an efficient one, no matter if you go with the 3/4HP version or the higher ones.

As a consequence of this fact, this will be performing more with less efforts. That makes it sure that less stress, wear and tear take place on the motor parts and the body. Therefore, you can expect a longer lifespan from this model compared to many others.

Bottom Line

After the entire Pentair 340039 SuperFlo High-Performance Single Speed Pool Pump Review, we are certain that you’ve got the values that you’d receive from this pump in return for your investment.

But we would like to conclude our discussion with a final verdict. In case your pump is about 12,000 gallons or less in size, the 1.5 HP version of this pump will do just fine.

However, if your pump is bigger than that, or if you want to add plenty of water features within the pool. Then we would recommend you to go for other models that contain a motor power of 2 HP or more.
