Polaris Booster Pump Replacement question

Hello,

I have a Polaris Booster Pump that was damaged by a fire caused by a landscape lighting transformer.  It is an older PB4-60.  3/4 horsepower.

I have a 2 speed 1HP motor that I had taken off of an old Leisure Bay 10,000 series hot tub when the hot tub shell cracked. (I took off the parts and fittings before throwing the shell away as I'd replaced hot tub with a new one.

Can I use this motor to work on the Polaris booster pump housing.  The shaft threaded end seems to be a smaller size but I thought I could cut the shaft and add a shaft extension that would screw into the impeller. 

Will a 1 HP motor be too much for the 3/4 hp housing and internal guts on the booster pump housing?  Would you only wire this to run on high speed or is there a way to wire both High and low speeds?  How would it switch speeds if so?  With a manual switch installed perhaps? (This would seem to be time consuming as who would sit there and flip the switch daily?   

Thats my questions for now.  I'm sort of a novice on this and appreciate any help.

Steve

Hi Steve,

The internal guts of the pump could handle a 1 HP motor, my main concern would be if the motor will actually mount to your Polaris PB460 as many of the motors have different faces. If you have a dual speed motor normally you purchase a second T106 Dual Speed Timer Your normal timer would power the pump on and off and the Dual Speed Timer would switch between high and low speeds. We wrote a Guide on How to Install a Dual Speed Timer which you might helpful.

If this seems like too much then we do carry the Complete PB460 Polaris Booster Pump as well as the Polaris Booster Pump Replacement Motor if you decide to replace the motor then you will also need a Polaris Booster Pump Shaft Seal.

Thank You

Thank you for your reply. I did notice the face of the pump will not bolt to the motor. I took a piece of 3/4 plywood and cut a circle out and was intending on sliding this over the motor end, secured to another piece of plywood that the motor is going to sit on and be screwed down.  The pump assembly would then be secured to the plywood around the motor.  That's the plan.  Good plan?  Bad plan?  Am I setting myself up for a mental breakdown?   This mission has gone way beyond personal and I want to see it work if it only lasts a day.  :-)

One last silly question.  Since this motor is wired for high and low speeds, could I just wire it to run on low speed as the booster pump? Would that be enough power to make the Polaris work?  I'm just not sure what the volume of water flo difference from low to high would be.  It seems like it would be substantially less based on my recollection when it was used as a 2 speed in my leisure bay

Hi Steve,

I would really suggest replacing the motor with either of the 2 options I listed below...

the Complete PB460 Polaris Booster Pump as well as the Polaris Booster Pump Replacement Motor if you decide to replace the motor then you will also need a Polaris Booster Pump Shaft Seal.

If you go the route with the plywood most likely you will have leakage that will cause the motor to quickly go bad.

Thank You
