The Hydraflo™ is a patented, submersible pump that uses the power of hydraulics to drive the impeller via flexible hoses. This replaces a fixed motor, a long, rigid shaft and the supporting structure common to most pumps that can move very large quantities of water. The unique design allows the pump to be set up in hours – not months- eliminates most of the civil works necessary for installation – saving a lot of time and money, allows the pump to be portable and provides variable speed control.
