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.

Currently have a century HP1.5 SPL Part # 7-177760-23 Volt , Frame R48Y,Amps 12.4,PH1. RPM 3450. Is this the correct motor?

A  Answered on 4/30/2020 by InyoPools Product Specialist Patrick P.

Hi Dwayne, Yes the pump here would have the same motor as what you currently have listed.

Can you please tell me the difference between this pump and the sta rite? They look the exact same to me. I am trying to replace the pump I already have. I want the exact same one if possible. I have attached pictures of the info off of the pump I have now. Thanks!


A  Answered on 3/31/2020 by InyoPools Product Specialist Lennox H.

Hi, Amy. The only difference is the Brand name. Otherwise, all parts and components are the same between the Pentair and Sta-Rite Dynamo pumps.

I have just purchased a new Pentair Dynamo pump part No. 340197. I cant seem to find the collar union to the pump.

A  Answered on 8/11/2019 by InyoPools Product Specialist Lennox H.

Hi, Max. The Lock Nut is not available as a separate part, it will have to be purchased as part of this Union Kit - 352210.

When I try to use my hand held vacuum and put the one end of the hose in the skimmer basket it sucks the water out of the pump and the pump won't pick the water back up until I remove the hose. I never had this problem before and I think it's the pump/motor on this new replacement pump I got last year. Please advise

A  Answered on 5/28/2019 by InyoPools Product Specialist Steve M.

Ronald, this issue is surely abnormal. What is the model number off of the cleaner you are using? Does the head of the cleaner stay in the pool when you plug it in? Have you inspected the hoses for damage? Any cracks, anywhere where the vacuum might be sucking up air?

I show that this is the pump that we have for 24 round pool. We pulled the number and information off of our current pump. The only difference is our old pump with this number shows that it is 1.5hp and this shows 1hp. Has this changed or do we need a different pump?

A  Answered on 5/3/2018 by InyoPools Product Specialist Lennox H.

Hi, Donna. The pump hasn't changed, the pump you have is just labeled differently.

I need to replace a pool pump motor. P/N 340197 Dynamo. Please advise what you have to replace it.

A  Answered on 5/16/2017 by InyoPools Product Specialist Patrick P.

Hi Lisa, the BN25 1 HP Replacement Motor is the correct motor for the Dynamo 340197 pump. When replacing this motor we also suggest this Dynamo Seal Kit

I have an 16,000 gal above ground pool with sta-rite T-210WF 200lb sand filter rated at 44usgpm, 35psi. I currently have a sta-rite JWPAS5F-2A4 pump assem. 1 1/2".What pump would you recommend? Also I would like to go up to 240 volt. Thanks, Robert

A  Answered on 8/24/2016 by InyoPools Product Specialist Scott W.

If you want a 220V pump it'll have to be an inground pool pump. Which isn't a problem, you just have to be able to plumb it properly. If you wanted a recommendation though I would go with part number P6RA6E205L for your current system.

?     Asked on 8/14/2016by Pauline Duffy

Is this 115 volts?

A  Answered on 9/30/2016 by InyoPools Product Specialist Joe S.

Yes this pump is a 115 Volts

What can I purchase to replace my Sta-Rite pump #JWPA5EL-2A2 ??

A  Answered on 6/4/2016 by InyoPools Product Specialist Lennox H.

Hi Herbie, The Sta-Rite Dynamo Pump 1 HP w/ STD Cord - 340197SR is the correct Dynamo pump that will replace the JWPA5EL-2A2.

?     Asked on 3/26/2016by rich

would this pump be a good replacement for a Pentair 1 1/2 Challenger Pump ? I am using it to pump out ground water under my inground pool , when we have flooding rain.

A  Answered on 3/26/2016 by InyoPools Product Specialist Lennox H.

Hi Rich, This pump would not be a good replacement for a Pentair Challenger pump. You will need a in-ground pool pump not an above ground pool pump to accomplish that task. We do have the Pentair Challenger Pumps available.

I have received your dynamo pump 1 hp part no.340197 the only problem is that the outlet on the impeller housing is to small I need an adapter to make it larger so that the original hose can be screwed on to it. any suggestions the original hose is larger than the dynamo outlet

A  Answered on 3/2/2016 by InyoPools Product Specialist Hector F.

You should be able to use a saddle clamp to clamp the hose to a smaller diameter pvc pipe that can insert into the hose itself.

I'm trying to replace a Sta Rite ABG4E-2A4 above ground pump and this pump seems like a good replacement. Is that so?

A  Answered on 7/11/2015 by InyoPools Product Specialist Hector F.

Yes this model is a good replacement. Keep in mind that if you have specific hose union connections that they may not work and you may need to use standard male threaded nipples to clamp standard above ground hoses to them.

?     Asked on 7/11/2015by Breton Enloe

will this pump allow you to turn the discharge to the side?

A  Answered on 7/12/2015 by InyoPools Product Specialist Patrick P.

Yes you can remove the screws on the pump housing to rotate the discharge port making it side discharge.
