Gear Pump for Hydroelectric Power Generation

A gear pump unit for hydroelectric power generation, comprising:

• a gear pump comprising:
• a case comprising a fluid inlet and an outlet;
• a first rotor in the case, the first rotor comprising a first plurality of radially spaced teeth, wherein the first plurality of radially spaced teeth wrap around the first rotor helically in a clockwise direction;
• a second rotor in the case, the second rotor comprising a second plurality of radially spaced teeth, wherein the second plurality of radially spaced teeth wrap around the second rotor helically in a counter-clockwise direction, and wherein the first plurality of teeth mesh with the second plurality of teeth;
• and
• a shaft operatively connected to the first rotor and to the second rotor;
• a generator operatively connected to the shaft;
• and
• a control module operatively connected to the gear pump and configured to selectively rotate the first rotor in a first direction and to selectively rotate the second rotor in a second direction, the control mechanism further configured to selectively reverse the rotation direction of the first rotor and to selectively reverse the rotation direction of the second rotor.
