Dynamo® Pumps excellence in hydraulic engineering provide that elusive combination of high efficiency, quiet operation, and longevity. These two-speed pumps carry different advantages to each of their two speeds. Switch between high and low speeds with the flick of a switch!

  • Run on low speed for energy efficient operation
  • Run on high speed when you need to backwash some filters (not AquaBead or AlphaONE filters, these backwash easily on low speed) or when you want to really make your waterfall roar, exercise your koi or add extra oxygen to the pond.
