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.

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?

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

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.

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.

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.

Does this have the ON/OFF switch?

A  Answered on 3/16/2016 by InyoPools Product Specialist Lennox H.

HI, This pump does not come with an On/Off switch, you will need to order model # 340290.
