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.

My model number is B661. I ask a question earlier to see it I could use this to replace my old pump.

A  Answered on 9/13/2016 by InyoPools Product Specialist Scott W.

That is the model number from your motor. If you would like to attach a picture of your complete pump, not just the motor, I will be able to identify it for you and be able to recommend a suitable pump for you.

Can I use this pump in the replace of my old one. Part no. 7-165198-06 Volts. 208-230/115?

A  Answered on 9/13/2016 by InyoPools Product Specialist Scott W.

I'm not able to gauge a replacement pump by the part number from the motor. I would need to know what model your pump is to recommend a suitable replacement pump for you.
