Pentair Dynamo Above Ground Pool Pump

Dynamo® pumps are an example of excellence in hydraulic engineering for that elusive combination of high efficiency and longevity. The key is a proprietary internal design evolved and refined over the past 40 years. The result is the ability to minimize friction and turbulence as water moves through the pump. Other pumps simply work harder, consume more energy and make more noise. By contrast, Dynamo pumps are so efficient they typically require lower horsepower motors to deliver required flow—this slashes energy costs. Superior efficiency also translates directly into quieter operation. Put a Dynamo to work on your pool for maximum performance and value over the long term.

Features include:

  • Unique diffuser and impeller provide excellent pressure performance across a wide range of desired flow rates— the hydraulic efficiency that keeps operating costs at a minimum.
  • Self-priming design protects internal components and ensures long life.
  • Components are constructed from fiberglass-reinforced material for superior strength, durability and resistance to aging and the elements.
  • Three horsepower ratings available to precisely match up with your pool’s circulation needs.

You can depend on Dynamo® aboveground pumps year after year because they are designed to perform and built to last. These pumps feature durable components of fiberglass reinforced thermoplastic to resist corrosion and fatigue for extended service life.

  • Available in a variety of models to meet your exact requirements—single-speed with cord and on/off switch; single-speed with cord, base and on/off switch; single or two-speed without cord.
  • Every Dynamo pump is performance and pressure tested prior to shipment to ensure superior quality.
  • One-year limited warranty.

Can i buy a pump from you and install it - I am being told a 'professional' must do the install also my pool has 2 drains in teh center - what are they for and how do i know what does what?

A  Answered on 10/22/2020 by InyoPools Product Specialist Eric J.

Good afternoon, thank you for choosing inyo pools. Yes, you can purchase a pool pump from us, some manufacturers do require a professional installation to ensure the manufacturer's warranty is not voided. The two drains in your main pool are more than likely the main drains that suck water into the system.

I have a model 340210 Pentair Dynamo High Performance pump. The plastic dome cover to the strainer basket has several cracks. I need a way to price and order a replacement. The part leaks water when the pump is off and leaks air when the pump is working. Please help!!

A  Answered on 12/4/2020 by InyoPools Product Specialist Hector F.

Hi Kurt, for the Pentair Dynamo series pool pump there are two lid options. The generic part number 25307-000-020 and the original Pentair version part number 5004-14

can you change the position of the cord

A  Answered on 9/3/2018 by InyoPools Product Specialist Lennox H.

Hi, Mike. Yes, you can change the power cord from the 3 o'clock position to the 12 o'clock position.

You recommend model # 340290 to get an on/off switch,but this model is $120 more. Is that the cost of the switch or are there other features different than the 340210?

A  Answered on 7/2/2017 by InyoPools Product Specialist Alex V.

Don, There are no other features on the switched version other than the switch. The other option would be to purchase a timer or to have the outlet connected to a switch to turn the pump on and off. Otherwise, the pump will run all the time.

what type of warranty is on the 1.5 hp above ground pool motor. We bought this system from Charles Shuler Pool Company 4/30/2015. this motor should last longer than 16 months.

A  Answered on 8/30/2016 by InyoPools Product Specialist Scott W.

It has a 1 year warranty on that pump. Pentair is pretty strict on their warranties, but it wouldn't hurt giving them a call to see if they will do anything. And I agree, they should last longer than 16 months.

A  Answered on 8/7/2016 by InyoPools Product Specialist Lennox H.

Hi Tim, Once it ships is will take 3-4 business days.

My original pump is 10 years old and starting to leak at the seal. I cannot separate the motor from the pump. It is a JWPAS5F-2A4. Is this a suitable replacement? If so, what is the thread pattern on the pump discharge?

A  Answered on 11/2/2015 by InyoPools Product Specialist Joe S.

Hello Craig, this unit would be a good replacement for the unit you have. The suction and discharge of this unit are both 1-1/2" Female NPT.

My above ground pool is around 18000 gals...what horsepower motor and pump would work best?

A  Answered on 9/29/2015 by InyoPools Product Specialist Lennox H.

Hi Mike, Can you provide the model and or size of your pool filter, with that info we can tell what size pump would be recommended for your size pool.

?     Asked on 8/30/2015 by Brian

I have a crystal flo 2, 19 inch sand filter. 27 foot round 48 inch deep. Currently using an old 3/4 hp pump but not filtering good. Would this 1.5 hp pump work?

A  Answered on 9/2/2015 by InyoPools Product Specialist Lennox H.

Hi Brian, Going from 3/4 HP to 1.5 Hp is a big jump. I would first find out if if the pump or filter is the problem since it is not filter good. The 19" Crystal Flo II Sand filter is sized for a 1 HP pump not a 1.5 HP.

?     Asked on 7/20/2015 by Brenda

I have a 27' by 48 round pool and the pump motor is a Sta Rite JWPAS5F-2A4. Is this the pump I need to replace the one I have?

A  Answered on 7/22/2015 by InyoPools Product Specialist Lennox H.

Hi Brenda, The Sta-Rite JWPAS5F-2A4 Pump has been replaced with the 1-1/2 HP Dynamo Pump w/ STD Cord.
