Questions for: Hayward Northstar 1 1/2 HP Single Speed Pump SP4010X15NS

Got a Question?

? 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?

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.

I am looking to replace the motor on my Hayward northstar pump, sp401 series. Is it possible to just buy the motor?

Hi Lisa, Yes, you can replace just the motor. Look at the label on your current pump for the SF value. If it is 1.60, your replacement motor is an A.O. Smith 1.5 HP Full Rated North Star Replacement Motor - SN1152. If the SF value is 1.25, your replacement motor is an A.O. Smith 1 1/2 HP Up Rated Northstar Replacement Motor - USN1152. Remember to replace the shaft seal.

Hello, Mike. The replacement motor and shaft seal for the SP4010X15NS is the USN1152 - A.O. Smith 1 1/2 HP Up Rated Motor and the SPX4000SA2 Seal Assembly. We also offer the Tune Up Kit Hayward Northstar 4000 Series Pumps (Pre-2003) - GOKIT66. You may click here to view the schematic for all parts available to order.

I have this pool pump which I want to replace. I'm hoping that I can get a identical match up so that it fits in with no piping modification. The old pump I will be replacing the bearings and keeping it as a spare

Hi Dave, Unfortunately the Hayward Northstar Pump was discontinued without a direct replacement. The closest pump would be this Hayward TriStar 1.5 HP UpRated Pump
