Hydraulic ram pumps and Sling Pumps

Paddle Wheel PumpA second pump that uses the energy of a flowing stream is the Paddle Wheel orPaddle Pump. A frame that contains the rotating drive paddles and the pumpfloats in the stream and is anchored to the shore, as shown in Figure 7, below.The depth the paddles are immersed into the stream can be adjusted. This pumpmay operate in less water depth than the Sling Pump, but would need paddles andstream width sufficient to pump the same amount of water. The paddle pump sizemay be built to pump larger volumes than the Sling Pump but like it, specificoperating conditions are required:► a depth of water sufficient to submerge the paddles• this will vary with the depth adjustment of the paddles► a water velocity sufficient to rotate the paddles• this flow may be a “lazy” flow as the paddles can be wide to capture alarge portion of stream flow for pumping energyFigure 7 Paddle Pump from Little RiverLittle River Paddle Pump. Little River Company is developing a paddlepump which has two pumps that are driven with the shaft of the rotating paddles.Outputs of 20 litres (5 USgpm) and 6m (20 ft) lifts are reported.
