Dynamo External Pump Models
These are versatile and workhorse pumps. Excellence in hydraulic engineering and providing that elusive combination of high efficiency, quiet operation and longevity. Run on low speed for energy efficient operation. Run on high speed when you need to backwash some filters (excluding AquaBead or AlphaONE as these filters backwash easily on low speed) or when you want to make your waterfall roar, exercise your koi or simply add oxygen to the pond. Go from low to high with the flick of a switch and back again! Available in 3 sizes. Price includes cord and basket assembly. 1.5" openings, 1.5" x 2" unions available. One year warranty.
