i have a Hayward super pump AO smith century dual speed 1.5 hp sp1610z2msc pool pump I need a replacement. What should I get?

A     Answered on 9/27/2017 by InyoPools Product Specialist Lennox H.

Hi, Henry. You can use either the B2975 or STS1102R as a replacement. I would also recommend getting the Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT.

I have an RS1502 Hayward pump with a 2 speed 1 1/2 HP A.O. Smith SP1610Z2MC. Would this motor (STS1152R) be an exact replacement.

A     Answered on 7/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Jonathan. This Century STS1152R motor is the correct replacement for SP1610Z2MC. I would also recommend getting GOKIT2 which includes the pump seal and gaskets.

What is the most energy efficient motor and can I change just the motor that is connected to the pump or do you have to change it all. Old motoer number is K48M2N123

A     Answered on 7/18/2017 by InyoPools Product Specialist Lennox H.

Hi, Don. You can change just the motor with either the STS1152R or ECM27CU motor.

I have a Hayward Super Pump with a Hayward Century single-speed motor (model C48L2N134B1). Twice overnight the motor has completely stopped (wall power switch still in the on position), so I'm assuming it's overheating. (It will start working again after 5 hours or so.) I'd like to replace it with a dual-speed motor. Is model STS1152R a good match? What else do I need to change to two speeds? I don't currently have a timer, but I'm happy to control a dual-speed manually.

A     Answered on 7/10/2017 by InyoPools Product Specialist Patrick P.

My suggestion would be the B2975T Dual Speed Replacement Motor with Timer I love this motor as it has a digital timer built right into the top of the motor which makes installation very simple. The B2975T is a 1 HP Full Rate motor which is identical to your 1.5 HP up rate motor. I would also suggest a Hayward Super Pump Seal Kit when you do your replacement.

I have a 1hp variable speed hayward pool pump that has gone bad and would like to upgrade with a 1 1/2hp variable speed. Would this motor fit? Also, I have a controller that switches speeds, so there is no need for manual switch, correct? Thank you

A     Answered on 6/18/2017 by InyoPools Product Specialist Patrick P.

Hi Mark, if you have the Hayward Super Pump or Super II pump then you would need the variable speed replacement motor listed here - 1.65 HP Round Flange Variable Speed Pool Motor. For this motor you will need a timer to power the motor on and off and then all the timer functions and RPM control is done directly on the controller on the motor.

I have a 3 year old AO Smith SP1615Z2MC motor that completely rusted out the top cover. I see there are protective pump covers - is this the solution to the problem or is it just a Band-Aid fix to have a protective pump cover? My original pump motor lasted 15 years but it didn't have a top cover. Is this just a poor design and I should look for a different motor design?

A     Answered on 5/4/2017 by InyoPools Product Specialist Lennox H.

Hi. The Protective Motor Cover will prevent rusting that is caused by water pouring down on the motor. There is nothing wrong with the design of the motor.

I need a replacement for a C48L2N36 Hayward / AO Smith superpump It is two speed 1.5 and .25 hp 220 volt Also is there an alternate which is 2 HP which will fit? It is for an swim spa I might consider upping it a half horsepower. So what models have the same flange ? Thanks ! Tim

A     Answered on 3/21/2017 by InyoPools Product Specialist Lennox H.

Hi, Tim. The STS1102R is the correct replacement for your current motor. The STS1152R would be the step up from the motor to the 2 HP since these motors are considered Full Rate. Due to a higher service factor, full rate motors have a higher total hp that what they're rated for. If you do go with the STS1152R motor you will need to change the impeller with p/n SPX2615C or the STS1202VR1 motor will require p/n SPX1621C (impeller) and SPX1616B (Diffuser) along with the Hayward Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT.

WILL THIS REPLACE A CENTURY MODEL # C48L2N134B1

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

Hi, Pat.The UST1152 single speed motor is the direct replacement for model # C48L2N134B1. If you would like to convert to a dual speed motor here are your options; the STS1102 in addition to the End Cover Switch Assembly (1011431-001) or the T106R Timer or the B975T motors.

My impeller broke (original pump install in 2005,) this will be my second motor replacement for this Hayward dual speed Super II pump. Which impeller do I use with the STS1152R? The original 3010c states it for a 1 1/2 hp up rated or 1 hp full rated motor and this new motor is full rated at 1 1/2 hp. From looking on your site, the 3015c looks to be rated for a 1 1/2 hp pump. Thanks.

A     Answered on 12/27/2016 by InyoPools Product Specialist Adam Y.

I would need your pump model to confirm but I am showing Impeller, Sp3015-c, Hayward (spx3015c) as the correct part. If your pump is a sp3016 than you would need Hayward (spx3016c)

I want to replace the motor on my North Star pump. The motor is SP1615Z2BC, Part 7-177106-01. Is this the exact replacement motor?

A     Answered on 1/15/2016 by InyoPools Product Specialist Lennox H.

Hi Neil, The A.O. Smith 1-1/2 HP Round Flange Dual Speed Full Rate Motor (STS1152R) is an exact replacement to p/n 7-177106-01.

?     Asked on 9/1/2015 by Jose

What specific capacitor on this unit? The fact that the high speed does not work but the low speed does work on this dual speed could be the capacitor atop the motor? Please shed some light

A     Answered on 9/7/2015 by InyoPools Product Specialist Lennox H.

Hi Jose, We do not have the specs of the capacitors for the STS1152 Dual Speed motor. You will have to get the specs off of the run capacitor to find the correct replacement.

I have an SP3015EEAZ pump (single speed motor ST1152) that has a bad motor. I want to replace the motor with a dual speed motor like the STS1152. Will the new motor fit?

A     Answered on 7/15/2015 by InyoPools Product Specialist Lennox H.

Hi Doug, The A.O. Smith 1-1/2 HP Round Flange Dual Speed Full Rate Motor (STS1152R) will be the correct Dual Speed for the Hayward SP3015EEAZ pump. I would recommend getting a Hayward Super II Pump Tune Up Kit (GOKIT2) and a Intermatic Dual Speed Pump Timer (T106R) if you do not have a controller.

Hi, I am trying to replace a Hayward motor w/ the following specifications: A.O. Smith Century Two Speed 1081 Pool & Spa P/N 7-177106-01 HP 1.5 - 2.5 Code G SP1615Z2BC SF1.3 RPM 3450/1725 AMPS 9.1/3.4 It is controlled with an Blue Haven (Goldline Aqua Logic) controller. Can you help me out with everything I need, i.e correct motor, timer??, replacement seals, gaskets, etc? Thank you, Dave S.

A     Answered on 6/18/2015 by InyoPools Product Specialist Patrick P.

Hi Dave, The motor on this page would be the correct replacement motor based on the information you supplied. The controller you already have would be fine to control this motor unless the controller has gone bad. As far as the tune up kit goes could you reply back to the email which was sent to you with a couple photos of your pump, this would allow us to recommend the proper tune up kit.

?     Asked on 5/27/2015 by Del

According to the product description of this 1.5 HP super pump, 2 speed replacement motor, it is shipped LESS HI/LOW SWITCH. This means there is no Hi/LO switch? So, how can I manually switch it to Hi or Lo, Joe S? Will this motor fit in my old 1.5 HP Hayward super pump housing? Thanks.

A     Answered on 5/28/2015 by InyoPools Product Specialist Patrick P.

Hi Del, You are correct this motor does not have a Hi/Lo switch and is only controlled through an outside timer purchased separately. If you want a manual toggle switch for the Hi/Lo then you would need the complete hayward super pump 1.5 HP SP2610X152S which includes the "Hi/Lo" switch on the back of the motor for manual switching of speeds. If you just want to replace the motor then we highly recommend the dual speed motor with integrated digital timer as the installation and wiring is so much easier than the manual switch. The digital timer allows you to manually switch between speeds or you can program the timer to run a different speeds throughout the day. Also the digital timer dual speed motor is less expensive than going with the dual speed motor and then purchasing a separate timer.

?     Asked on 5/27/2015 by Del

I would like to replace my Hayward super pump 1.5 HP single speed with a 2 speed Hayward super pump, same HP. You mentioned, we can purchase a toggle switch or a timer. How do you make the electrical connections? I currently have a combination 220 and 110 v outlets by my pump. I just plug my 3 prong cord from the super pump to my outlet, which is connected to my regular timer which is located in my garage approx. 100 ft. away from the pump, filter & gas heater.

A     Answered on 5/27/2015 by InyoPools Product Specialist Joe S.

Hi Del, the hayward super pump 1.5 SP2610X152S includes "Hi/Lo" switch on the back of the motor so you would still need to do it manual unless you upgrade to a newer timer or automantion system
