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.

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

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

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.

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.

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.

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.
