Quiet, efficient and super-reliable performance

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.

  1. I’ve had this pump for about 6 years and have changed the seal on the pump 3 times ( I think from putting chlorine tabs straight in skimmer basket) The problem I have had is the plugs in the bottom of the pump blew out because of the plastic threads on the plug other than that the pump is very reliable
