Hydraflo™‘s are the only very large pumps that can be quickly picked up and moved around and then quickly installed. David Eller developed and patented the Hydraflo™. Today only two other companies make a similar pump and only in sizes below 24″. The propeller or impeller is driven by a hydraulic motor that is connected to a diesel engine or electric motor drive unit by flexible hydraulic hoses. That gives enormous flexibility in placement of the units and makes them quick and easy to install. Our 30 inch units are capable of 38,000 gallons per minute at a 10 foot head and the 42 inch units can pump 70,000 gallons per minute at a similar head.
