PowerFlo Matrix Above-Ground Pump Series

The Big news in above-ground pumps is the PowerFlo Matrix by Hayward. It features an industrial-size strainer basket to collect a lot of debris without a lot of maintenance.

The high-quality Noryl impeller offers wide openings to prevent leaf and debris clog. While this pump is impressively equipped, the PowerFlo Matrix is also very efficient. It has a heat-resistant, double-size seal and a protected rear-mounted switch for high-energy efficiency. Plus, its heavy-duty, high-performance motor provides years of trouble-free operation thanks to an integrated automatic thermal overload protector. PowerFlow Matrix clearly the superior choice in above-ground-pool pumps.

The Power-Flo Matrix has been engineered as a uniquely superior above-ground pool pump. With a single push of a button, this truly versatile pump changes from a veritical to a horizontal discharge and back again. Its large profile and integrated styling makes the Power-Flo Matrix a swimming pool pump like no other.

Would this pump be a good fit with the Hayward C-550 cartridge filter?

A  Answered on 5/7/2020 by InyoPools Product Specialist Patrick P.

Hi Emily as long as you have an above ground pool and your pump will be placed below the water level of your pool then yes this would be a good fit for the C-550 filter.

Hi, The switch on my programmable pump has broken. I am unsure as to how I can get a replacement. Any ideas? Thanks

A  Answered on 5/16/2018 by InyoPools Product Specialist Andy O.

Hello Tom- If you need just the switch you would need the On Off Motor Switch (spx1500s8). The whole back portion of the motor that includes the timer is Hayward Above Ground Pool Pump Timer Microprocessor - SP1500FT but is no longer available.

How you determine horsepower for pump? My pool has 20,000 gal.

A  Answered on 3/6/2017 by InyoPools Product Specialist Lennox H.

Hi, Rolando. The pump size would be based on the size of the pool, location of the pump, filter size and whether you have any additional features. For a 20,000 gallon above ground pool with a large enough filter can use a 1.5 HP pump.

?     Asked on 7/15/2016 by Tom

My SP1593FP pump motor went out, and i found an SP1580X15 pump locally. From what I found online the output is very close to each other. But when I hooked up the 1580X15 to the 27 ft diameter above ground pool, the flow is hardly enough to even hold the vacuum adapter and dos win place when I vacuum the pool.

A  Answered on 7/21/2016 by InyoPools Product Specialist Lennox H.

Hi Tom, You might need to check and or clean out the filter to see if that is causing the low suction problem.

Hi Bob, The Hayward Matrix Pump 1.5 HP Dual Speed-SP15932S is the correct replacement pump. We're unable to get the bearings and thru bolt for the SPX1515Z2ES motor, you can try contacting Hayward at 908.355.7995.

I had the basket off to look at the impeller it didnt spin real free. This pump run really good for about month. It is 2 year old now it has weak pressure. I back wash many times. The sand is 2 years old. What do you think

A  Answered on 6/24/2015 by InyoPools Product Specialist Dennis R.

Mark - You might have to take the motor out of the pump housing to see why the impeller is not spinning freely. It may be cracked or loose or debris might be clogging it. Also check the diffuser. When you have the motor out and the impeller still doesn't spin freely, your motor bearings may be bad. See our guide on "How To Replace A Pool Pump Impeller" for information on pulling out the motor. You will not have to replace the impeller just ot look at it.

I need an o-ring for the pot (strainer) of this pump. About 7" OD. All the O-Rings I've found are about 5 1/2" OD. Can you help me find one?

Ed, Yes. We carry the Hayward Matrix strainer cover o-ring.

Is there a cheaper replacement pump an motor than the power flo matrix that hooks up the dame

A  Answered on 5/13/2015 by InyoPools Product Specialist Patrick P.

Hi Terry, This 1-1/2 HP Above Ground Pool Pump would be a good alternative to the Hayward Power Flo Matrix. I would double check the Port Locations & Dimensions on the pump I supplied to make sure it will work with your set up.

Hello I asked this question about the impeller for the hayward pool pump but the answer you gave me back was for an 3/4 and 1 horse pumps, I have a 1.5 pump. I need the impeller and all the gaskets, seals, grease to install it. Again what is says on my pump is hayward matrix power flow 1.5 Sp 1593 what else might you need. Is there a kit that has all involved or just separate

A  Answered on 4/27/2015 by InyoPools Product Specialist Patrick P.

Hi Bo sorry for any confusion, it looks like Hayward uses the same impeller for both there 1 HP, 1-1/2 HP and 2 HP Matrix pumps, which is this Matrix Impeller. The seals and gaskets are sold individually and not as a kit and all of those items were listed in the last reply with links to each product, those items will be all that you need.

My Hayward pump stopped working

Written on 11/1/2018 by Guest

I determined that the problem was the motor on my Hayward above ground 1-1/2 hp pump. I purchased the entire pump and motor from Inyo Pools because it was more reasonable to buy the entire unit and get a new pump at the same time. The pump came with the discharge facing upward, I followed the easy step by step instructions and in less than 10 mins I had a side discharge pump. Installing the new pump to filter was easy; two bolts to the plastic base of the filter and a hand tightening connection to the filter itself.

Were these instructions helpful?
