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.

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

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.

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.

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.

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.

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.
