Ornel Floodlifter Mechanical and Hydraulic Design

All pumps in the range are pure “"Axial-Flow" and the design based on Mr Hugh Nelsons original design theory and experimental results. Testing of the design has proved the effectiveness of the “"air-foil” shaped blade sections in minimizing cavitation. The low pressure zone is spread over the whole of the lower surface of each impeller blade, not concentrated near the leading edge. This means that the turbines can operate at above-average speeds and flow rates without cavitating.

The basic unit of all pumps in the range is the "Stage” consisting of one axial-flow impeller followed by one "'stator", or "bowl'. The stator blading is also of air-foil-shaped section and performs the important function of converting rotational velocity energy to pressure energy. The Total Head per stage under normal conditions of shallow submergence, within cavitation limits, is a maximum of 12 meters (40 ft.) for the No. 4 impeller and 6 meters (20 ft. ) for the No. 8 impeller. Any number of stages can be assembled together to obtain the required Total Head.

Ornel Turbine Standardization

The range of pumps consists of a series of sizes: 6", 8” 12", 16", 24", 36" (48” and 64"). In each size, a range of standardized impellers is used, all interchangeable, from the No. 3 having a low blade angle to the No. 8 with a high angle, giving high flow rate.

By selecting any number of stages and any impeller type a particular Total Head and Flow Rate can be obtained at best efficiency and to suit a particular shaft speed. This means that all pumps can be directly-driven by standard electric motors and diesel engines.
