Hello Elio.  The published Performance Data for the Hayward NorthStar model SP4015X20NS indicates a flow rate of 118 gallons per minute (GPM) at 50 Feet of Head.  The Hayward TriStar Single Speed 1.0 HP (1.85 THP) Full Rate Energy Efficient Pool Pump model W3SP3210EE is rated 105 GPM at 50 Feet of Head.  Hayward TriStar 1 HP, Energy Efficient, Full Rated Pump  The Hayward TriStar 1.85 HP Variable Speed Pool Pump model W3SP3202VSP is rated 105 GPM at 50 Feet of Head, high speed.  Either of these pumps would be an excellent replacement for the Hayward NorthStar.

This comes factory set at 230V. Do I need to switch the wires and set it at 115V? What voltage do these typically run at?

A  Answered on 9/16/2020 by InyoPools Product Specialist Robert M.

This model is obsolete and no longer available. It can be switched to 115V if needed. However, the majority of inground pool pumps run on 230v. We recommend testing the voltage before switching the voltage setting of the pump.

I have the SP4015X2ONS Serial # 630033. I need a new clear lid. Will the Strainer Cover Kit (2007 & Prior) - SPX4000DLT work for this model?


A  Answered on 4/4/2020 by InyoPools Product Specialist Patrick P.

Hi Christy, Yes you will need this SPX4000DLT NorthStar Lid for your pump shown in the photos.

I currently have the Northstar SP4015X20NS 2HP. I see the other comments for comparable current Hayward models, what would be the comparable Pentair model for my application? I just replaced my Hayward sand filter last year to a pentair CCP420 filter? Thanks

A  Answered on 9/10/2019 by InyoPools Product Specialist Joe S.

We would recommend the Sta-Rite Max-E-Pro 2 HP Up Rate Standard - P6RA6G-207L.

pump goes on for a minute or less then shuts off. the motor is very hot to the touch. what causes this?. Hayward northstar Model sp4015x20ns

A  Answered on 12/17/2018 by InyoPools Product Specialist Lennox H.

Hi. This issue can be caused by several factors, check out our How To Troubleshoot a Pool Pump Motor - Motor Overheated guide for details.

is there a tool to take off the lid on the SP4014x20ns. The lid is extremely hard to get off with out using a mallet

A  Answered on 3/27/2018 by InyoPools Product Specialist Hector F.

There is no listed tool for this model pump. I would advise that once you get the lid removed to use magic lube on the o ring and lid seal to make future removal easier.

What is the replacement pump for nolrthstar SP4015X20NS. Energy efficient not too much plumbing

A  Answered on 5/3/2017 by InyoPools Product Specialist Lennox H.

Hi, Joe. The Hayward TriStar 1.5 HP Full Rate EE Pump - SP3215EE is the best replacement for the Hayward Northstar Pump - SP4015X20NS.

Do you know which Run Capacitor I need for the Hayward SP4015X20NS USN1202 motor?

A  Answered on 2/27/2017 by InyoPools Product Specialist Andy O.

Hello- The Capacitor, Run 370v 35 Mfd (rd-35-370) part number 628318-309 is what is listed by the manufacturer for your USN1202

?     Asked on 1/12/2017by Stefan

Hello! The motor on my Northstar SP4015X20NS died and I would like to replace just the motor with either a 2-speed or variable speed motor. Is there a variable speed motor that will work or do you only recommend the Hayward SPX1615Z2MNS 2-speed, 2HP unrated motor you have listed on the parts page. Thanks!

A  Answered on 1/12/2017 by InyoPools Product Specialist Scott W.

Part number ECM27CU is a great variable speed motor that will fit your Northstar. Is your Northstar before 2007 or after 2007 model, that is going to matter for the shaft seal because the two difference Northstars have two difference shaft seals. You will want to replace the shaft seal when you do the motor installation.

What replaces the SP4015X20NS Hayward Northstar pump since this is no longer available?

A  Answered on 2/22/2016 by InyoPools Product Specialist Andy O.

Hello, Jacky, The closest replacement for your SP4015x20ns Northstar Pool Pump 2 HP would be the SP3215X20 Hayward TriStar 2 HP, Max Rated Pump or SP3215EE Hayward TriStar 1-1/2 HP, Energy Efficient, Full Rated Pump. You will have to do some replumbing but they will be the closest in performance to the Northstar.

?     Asked on 7/30/2015by Jim

I have a Northstar Hayward SP4015X20NS pump and motor. The pump is leaking water from the back and underneath the pump. I tried to find a new one but all sites say it is obsolete. What is a direct replacement I can use? PS My motor is fine, can I just buy the pump>

A  Answered on 8/1/2015 by InyoPools Product Specialist Lennox H.

Hi Jim, There is not a direct replace for the Northstar Pool Pump 2 HP that will match up with the plumbing but performance wise the Hayward TriStar 1-1/2 HP, Energy Efficient, Full Rated Pump will be a suitable replacement. You will have to re-plumb this pump into your set up. You can purchase replacement parts, there is a  Northstar 1998-2007 and a Northstar 2008-Current version.

I need to replace the motor on a Hayward Northstar Pump SP4015X20NS. Could you recommend the correct 2HP motor?

A  Answered on 10/29/2014 by InyoPools Product Specialist Robert M.

Mike - The correct replacement motor for the Hayward SP4015X20NS would be model USN1202.

?     Asked on 1/18/2012by Guest

I have a Hayward NorthStar that I am looking to replace. The only one's I see all have a threaded union connection. Do you still carry the one with the Quad lock?

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

Unfortunately Hayward discontinued the Quad Lock design on the NorthStar pump models in 2007. The housing on the newer pumps is a threaded design and re-plumbing would be necessary.
