On model 340039, how to remove cover from electrical connection.

A  Answered on 12/14/2020 by InyoPools Product Specialist Hector F.

Hi Joseph, there is a small plate cover at the rear of the motor which can be removed by using a small nut driver.

I just need a 340039 pump my motor is fine it is a 1.5 hp .can I buy just a pump?

A  Answered on 11/23/2020 by InyoPools Product Specialist Hector F.

Hello, the correct single speed replacement motor for the original Superflo model 340039 pool pump is B854. You will also need a Pentair Superflo seal kit when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project.

?     Asked on 5/4/2020by Joe

Does the Pentair Superflo 340039 have its own power cord? The original model had its own dedicated plug.

A  Answered on 5/4/2020 by InyoPools Product Specialist Patrick P.

Hi Joe, No this Superflo 340039 does not come with its own power cord. You would remove the power cord from your current pump and install it on this pump which is an easy swap out.

  • Commented on 5/4/2020 by Product Owner

    can you provide the link for the power plug part on your website. I cannot find it to purchase it.

    • Commented on 5/4/2020 by InyoPools Product Specialist Patrick P.

      Hi Joe, Here is a link to the 3 Prong Plug and Cord please note that the cord can only be used for 115V wiring and not 240V. Also note that for some applications you may be using a 115V Twist Lock Plug The difference between the two is that the first cord has a standard 3 prong plug and the second is a twist lock.

Will this pump work with 1 1/2ā€ and 2ā€ lines? Iā€™m not sure what size my lines are.


A  Answered on 4/21/2020 by InyoPools Product Specialist Lennox H.

Hi, Louis. Yes, this pump can be used for either plumbing size.

I am replacing an old Pinnacle High Flo pump Centurion switchless motor for PAC-Fab. This pump was installed about 1998. 1 1/2 HP, 1.10 SF, Volts 230/115, Amps SF 8.0/16.0. Will the Pentair Superflo 1 1/2 HP High Performance pump replace this? What would you recommend?


A  Answered on 4/16/2020 by InyoPools Product Specialist Patrick P.

Hi Lou, Yes the Super Flo 340039 would be a great replacement for your old Pinnacle Pump. The plumbing ports are not in the exact some location so you may have a little bit of re-plumbing.

  • Commented on 4/16/2020 by Product Owner

    Is there something you would recommend that the plumbing ports are in the same place?

    • Commented on 4/16/2020 by InyoPools Product Specialist Patrick P.

      Hi Louis, Unfortunately, there is not a pump that has the plumbing ports in the exact same location. You could just replace the motor and keep your old Pinnacle housing. If you wanted to go this route you would need this 1.5 HP Pinnacle Replacement Motor and this Pentair Pinnacle Seal Kit

      • Commented on 4/16/2020 by Product Owner

        Ok. That won’t do me any good. The problem I have is leaking. The plastic ahead of the motor wore out and created a hole. I have siliconed but kept leaking last year. Are the ports far off?

        • Commented on 4/16/2020 by InyoPools Product Specialist Patrick P.

          Hi Louis, I don't have the port locations for the Pinnacle but I have attached the Port locations for the Super Flo which can find attached. I don't believe they should be too far off.

                One more question. With what I have there, is there another pump you recommend other than the Pentair SuperFlo or would that be my best bet?

                • Commented on 4/18/2020 by InyoPools Product Specialist Patrick P.

                  Based on the price point I really like the Waterway 1.5 HP SMF Pump and the quality is really good. This Pentair SuperFlo would also be a good option as well.

My pool is roughly 10-12 thousand gallons, My pump just went, 3rd pump in 8 years. they all were a hayward super pump 1&1/2 HP 115/230 im done with Haywood? what would u recommend?

A  Answered on 6/10/2019 by InyoPools Product Specialist Lennox H.

Hi, Chris. You can use the Pureline Prime 1.5 HP - PL2602, or this SuperFlo 1.5 HP - 340039 are suitable replacements. 

?     Asked on 6/3/2018by Jim

My pool which includes a spill over spa holds about 15,000 gallons. The current pool pump is a Sta Rite Dyna Glass MPRA6F-148 ( 1 1/2 Hp motor ) single speed pump. The tank and trap body has a crack in it. Will the Pentair 340039 superflo high performance single speed pump be a good replacement option for my pool.

A  Answered on 6/12/2018 by InyoPools Product Specialist Lennox H.

Hi, Jim. The Superflo Pump has a lower performing pump than the MPRA6F-148L pump. I would recommend the MPEA6F-206L. If you want to use the Superflo Pump, you will need the 2 HP - 340040

?     Asked on 9/13/2017by Samantha

Does this pump (Pentair SuperFlo 1.5hp) come with all the O-rings etc I will need when installing it? I am replacing an old version of the same pump.

A  Answered on 9/13/2017 by InyoPools Product Specialist Patrick P.

Hi Samantha, Yes the Pentair SuperFlo will come will all O-rings needed for installation. You may need some basic plumbing fittings and glue based on your plumbing set up and those items can be picked up at local hardware store.

I am replacing Pentair Superflow 1774528 with 1 1/2 HP pump .It looks like #340039 would be a good replacement pump. Do you have other suggestions?

A  Answered on 3/28/2017 by InyoPools Product Specialist Scott W.

Are you looking to replacement the complete pump or just the motor?

Current pump was not working anymore.

Written on 3/12/2018 by Guest

Easy to install.
First of all, take pictures of current pump and all connections (handy to reference during installation of new one).
Second, shut off power at the breaker (double check for sure!)
Remove all connections to current pump, move from site
Place current pump on same site as old pump, Make sure pump is level (took me a few tries to get this right so it didn't leak/rattle)
Make all connections
Turn power back on, turn pump on
