Install price for replacement pump: 2.6HP Pentair WhisperFlo VST

C,

The install price has a lot to do with what has to happen for your new pump to fit... And also how your current pump is plumbed.

I've seen some that would take an hour, and others where several valves would also have to be replaced just to make things fit.

Show us some pics of your equipment pad.

Thanks,

Jim R.
 
Tough call on whether to assume bad bearings and attempt a self-repair of a 10 year old SS pump or spend the $3K to have a new VS pump "professionally" installed. We are expecting freezing temperatures over the next couple of weeks so timing would be a gamble...were the pump to not be repaired and fail during the freeze.

I see that the repair would (likely) merely require (2) bearings ($45.68), a Viton Pump Shaft Seal Kit ($24.31) and a Bearing Puller tool ($19.99) and then some good luck in attempting to repair the pump successfully without causing any additional damage for a total cost of $90 plus the time and potential frustration.

$3000 for a new VS pump with warranty and lower monthly electric bills vs $90 to keep an old SS pump alive.

You have a very nice pump with that TriStar. If you are able to do a bearing replacement, then you would be able to install a Nidec Neptune NPTQQ270 variable-speed motor even faster and have the benefits of a VSP that has built-in freeze protection. Or just run it 24/7 during freezing weather.

Are there any guides that can be followed when replacing motors for particular pumps wit the Nidec Neptune (just to be sure that all of the necessary seals and gaskets are orderd to properly mate)?

Are there any particular trusted retailers for buying the Nidec Neptune NPTQQ270?

My Hayward Tristar is currently connected to an Intermatic timer that handles scheduling and includes a temperature probe to run the pump when temps drop low. If I replace the motor with the Nidec Neptune, would I need to omit the Intermatic timer and configure schedule and freeze protection directly on the Nidec?

I am just trying to figure out how simple of a swap the NPTQQ270 motor would be when replacing the Century Centurion Motor B2840V1 on my Hayward Tristar SPX3200.

Thanks for the information!

I would use the low voltage control input vs. the motor low temp monitor.

Or, you can just allow it to run continuously at lower speeds if freezing is expected.

Low Temperature Monitor.

When the control senses the ambient temperature dropping below the threshold level (as defined by the installer/end-user), the control sends a command for the motor to run at 1200 RPM to help prevent water from freezing in the pool plumbing.

Refer to the Low Temp Monitor setting on page 22 for specific information covering the On/Off cycle and adjusting the temperature setting.

Low Temp Monitor.

The control monitors the ambient temperature of the pump.

If the temperature falls below a specified threshold, the pump begins cycling on and off to keep water from freezing in the pump.

If the pump is not currently running, the pump switches on for 30 minutes at 30% of the rated speed of the motor.

The pump then idles for 30 minutes.

If at the end of 30 minutes the temperature is still below the low temperature threshold, the cycle repeats itself.

By default, this feature is disabled.

The Low Temp Monitor threshold is configurable between a range of 32° F to 50° F (0° C to 10° C).

Thank you!!

My current setup there is an Intermatic P1353ME timer that controls the Hayward Tristar pump and a Pentair UltraTemp Heater/Cooler. When the pump shuts off, so does the Ultratemp (if it happens to be running). When I upgrade the Hayward motor to the Neptune (which has timer controls and a relay) would I eliminate the Intermatic Timer and connect the UltraTemp to the the Neptune relay so that the UltraTemp would only operate when the pump is running at a higher pump speed?

What to do about the current Intermatic timer setup is what makes me hesitate with the motor upgrade (which does seem rather simple, particularly in comparison to the bearing replacement route.

Thanks again

Much easier than replacing bearings then re-installing the motor back to the wet-end. You would need a GO-KT 80 V for shaft seal and new O rings, etc. Videos on replacing a TriStar motor are on YouTube:
The clock can be kept but you would move the wires from terminals 2 and 4 that go to the motor now to be with the wires on 1 and 3. The clock could then be used to control a SWG if you get one. The motors have built-in freeze protection that you enable from the menu.
Though my pump has freeze protection, I have found that running it daily starting at 2:00AM then off at 4:30 PM works for me, and, being a VSP running at lower RPMs, it costs me about $20.00 per month so I have never changed those times in over 30 years (at least 15 with my VSP). We have similar size pools.
Power to the new motor should be continuous, not switched on and off or freeze protection won't work. The motor installation manual is attached.
Programming of the Nidec motors is relatively easy but here is just one of many how-to videos on that motor:
