Pump as turbine

[1][2] Unlike other conventional machines which require being manufactured according to the client’s specifications, pumps are a very common piece of equipment widely available in different sizes and functionality anywhere around the globe.

During this time, established collaborations with several research institutes helped develop an in-depth understanding of the phenomena associated with PAT utilization.

[9] The name is derived from the radial path followed by the fluid in the rotor: from the centre to the periphery when running as a pump and in the opposite direction when flow is reversed.

Finally, mixed flow pumps/PATs stand in between the applicability range of radial and axial units and have an impeller shaped in a similar way as a Francis turbine.

[10] Another special pump/PAT design is that of submersible units, which can possibly be fitted inside a pipe connected to draft tube exploiting small head differences in flowing rivers.
